Introduction
The Association for Treatment of Neuroplastic Symptoms (Symptomatic.me) recommends evidence-based psychological techniques for diagnosis, treatment and relief from persistent pain or illness not caused by organ disease or structural injury. We refer to this form of illness as Neuroplastic Symptoms (NS) because it is generated by nerves in the brain (Neuro) and has the capacity for change (plastic). The symptoms include chronic pain, medically unexplained symptoms, chronic functional syndromes (such as fibromyalgia, irritable bowel syndrome and many others) and somatisation disorders. However, because a wide range of specialties has addressed these issues, the relevant science has been published in a very large number of journals making it a challenge to comprehensively review. Consequently, few clinicians are aware of the quality and quantity of evidence supporting a psychological approach to Neuroplastic Symptoms. The bibliography below compiles the most relevant published research. Each paper is annotated with a description of its key findings. You can search this document using Command-F.

“Reviewed 23 studies (13 RCTs and 10 case series with pre/post assessments) of ISTDP. Of these, 21/23 (91.3%), 11/12 (91.6%), 16/19 (76.2%) and 7/9 (77.8%) reported significant or possible effects on physical symptoms, psychological symptoms, social-occupational function and healthcare utilization respectively. Meta-analysis was possible for 14 studies and revealed significant effects on physical symptoms, psychiatric symptoms and social adjustment which were maintained in long-term follow-up.”

In the largest naturalistic evaluation of ISTDP, the long-term healthcare costs were assessed in 890 consecutively referred cases of which 61% had Somatoform Disorder: ISTDP treated cases had significantly reduced physician and hospital costs at 1-, 2-, and 3-year post treatment follow-up with a mean savings of over $12,000 by 3 year follow-up. A subsample of this population, consisting of 28 patients with psychogenic non-epileptic seizures who received ISTDP, exhibited similar improvements.

In meta-analyses of 17 RCTs, STPP significantly outperformed minimal treatment, treatment as usual, or waiting list controls on somatic symptom measures at all time frames, with small to large magnitude effect sizes. Descriptive reviews of 5 RCTs suggest that STPP performed at least as well as other bona fide psychological therapies. Limitations of this meta-analysis include small samples of studies and possible publication bias.

Intensive short-term dynamic psychotherapy (ISTDP) has been studied for
a broad range of somatic symptom presentations including chronic pain.
Ten studies, including 6 randomized controlled trials, were examined. ISTDP yielded large and persistent treatment effects for both pain and depression within group. When ISTDP was compared to cognitive behavioral therapy methods (CBT) in randomized controlled trials, it yielded superior effects to CBT on pain and depression measures in both
short- and medium-term follow-up. Two studies suggested the method
was cost effective by reducing healthcare costs, medication and disability costs.
Based on these findings ISTDP should be considered for chronic pain treatment guidelines.

doi:10.1001/jamapsychiatry.2021.2669
In this randomized clinical trial, 33 of 50 participants (66%) randomized to 4 weeks of pain reprocessing therapy were pain-free or nearly pain-free at posttreatment, compared with 10 of 51 participants (20%) randomized to placebo and 5 of 50 participants (10%) randomized to usual care, with gains largely maintained through 1-year follow-up. Treatment effects on pain were mediated by reduced beliefs that pain indicates tissue damage, and longitudinal functional magnetic resonance imaging showed reduced prefrontal responses to evoked back pain and increased resting prefrontal somatosensory connectivity in patients randomized to treatment relative to patients randomized to placebo or usual care. Psychological treatment focused on changing beliefs about the causes and threat value of primary chronic back pain may provide substantial and durable pain relief.

RCT of 36 patients with urinary symptoms without organic lesions with follow-up of 4 years. Of the 13 who received intensive short-term dynamic psychotherapy (14 weekly sessions), 10 had complete relief and 3 had significant improvement. Depression, anxiety and hostility also improved. The 23 controls had traditional urologic care and no significant improvement was found.

“This was an initial trial of a newly developed therapy aimed at psychological attribution and emotional awareness and expression. They treated 72 patients and did pre-and post- treatment assessments and a six-month follow-up. Pain was reduced following treatment, and was either maintained or enhanced at the six-month follow-up.”

“Patients with MUPS may best be viewed as having complex adaptive systems in which cognitive and physiological processes interact with each other and with their environment. Cognitive behavioural therapy and antidepressant drugs are both effective treatments, but their effects may be greatest when the patient feels empowered by their doctor to tackle their problem.”

MBSR and CBT were provided to groups for up to two hours weekly for eight weeks. Eighteen weeks after the sessions, clinically meaningful improvement in disability was found in 61% of MBSR and 58% of CBT patients but also in 44% of UC patients. Clinically meaningful improvement in how bothersome the pain felt was found in 44% of MBSR, 45% of CBT but only 27% of UC patients. These are modest benefits. Studies of Pain Reprocessing Therapy and Emotional Awareness and Expression Therapy have documented better outcomes.
14. Clarke, DD (2016). Diagnosis and treatment of medically unexplained symptoms and chronic functional syndromes. Families, Systems, & Health, 34(4), 309-316. The author cites the data that 25-33% of primary care patients have medically unexplained symptoms. He advocates a systematic approach to interviewing based on his experience with 7,000 MUS patients, leading to better outcomes. In so doing doctors can identify psychophysiologic disorders. He lays out ways of talking to patients who may be skeptical about psychological links to their physical symptoms, and also outlines a treatment approach, and the article is illustrated with numerous case vignettes.

Twenty-three adults under the age of 60 years with PASC were enrolled. The median duration of symptoms before joining the study was 267 days. Participants received PSRT during a 13-week (approximately 44-hour) course. Reduction in the median Somatic Symptom Score was 60%, in dyspnea (difficulty breathing) it was 80%, in pain 50%. At baseline, 57% strongly agreed that exercise made their symptoms worse. After 8 weeks only 4% strongly agreed.

During severe illness, the patient had major psychosocial impairment, high life stress, a low visceral pain threshold, and activation of the midcingulate cortex (MCC), prefrontal area 6/44, and the somatosensory cortex, areas associated with pain intensity encoding. When clinically improved, there was resolution in activation of these 3 areas, and this was associated with psychosocial improvement and an increased threshold to rectal distention.

Medically unexplained symptoms (MUS) are among the most common and frustrating in primary care. Our goal was to review published evidence to guide busy general practitioners working with a culturally diverse, challenging patient population coping with MUS. A search of PubMed and PsycINFO from 1985 to the present was conducted using MUS and related terms. The literature was then organised into sub-categories based on its relevance to primary care. We conclude with a description of gaps in the literature based on the literature review and the clinical experience of the authors.

A significantly greater proportion of patients in the CBT group had physical symptoms rated by clinicians as “very much improved” or “much improved” compared with those in the usual care group (60% vs 26%). The intervention’s effect on unexplained physical symptoms was greatest at treatment completion, led to relief of symptoms in more than one-half of the patients, and persisted months after the intervention, although its effectiveness gradually diminished.

For women, psychotherapy was found to be superior to supportive listening. There was a similar trend for men, but this did not reach significance. Following completion of the trial, patients in the control group were offered psychotherapy; 33 accepted and following treatment experienced a marked improvement in their symptoms. At follow-up 1 yr later, those patients who had received psychotherapy remained well, patients who had dropped out of the trial were unwell with severe symptoms.

We found low-quality evidence that mindfulness meditation is associated with a small
decrease in pain compared with all types of controls in 30 RCTs. Pain reduction was 19% for MM but 8% for controls. Statistically significant effects were also found for depression symptoms and quality of life.

Eleven trials were included. Significant, medium to large effect sizes were found for measures of pain acceptance and psychological flexibility. Significant small to medium effect sizes were found for measures of functioning, anxiety, and depression. Measures of pain intensity and quality of life were not significantly different from zero. Generally effect sizes were smaller at follow-up.

A meta-analysis of 22 RCTs showing small reductions in healthcare contacts and medication use with CBT compared with active controls, treatment as usual, and waiting list controls, but not for medical investigations or healthcare costs. Concludes that Cognitive Behavioural Interventions show weak benefits in reducing healthcare use in people with MUS.

A total of 31 controlled trials (29 randomized and 2 nonrandomized) was identified. Twenty-five studies targeted a specific syndrome (e.g. chronic fatigue, irritable bowel, pain) while 6 focused on more general somatization or hypochondriasis. Primary outcome assessment included physical symptoms, psychological distress and functional status in 28, 26 and 19 studies, respectively. Physical symptoms appeared the most responsive: CBT-treated patients improved more than control subjects in 71% of the studies and showed possibly greater improvement (i.e., a trend) in another 11% of the studies. A definite or possible advantage of CBT for reducing psychological distress was demonstrated in only 38% and 8% of studies respectively, and for improving functional status in 47% and 26%.

Forty-one trials were included in the meta-analysis, comprising data from 2290 individuals. Psychological therapies had a medium effect on GI symptom severity (effect size = 0.69) immediately after treatment. On average, individuals who received psychotherapy had a greater reduction in GI symptoms after treatment than 75% of individuals assigned to a control condition. After short-term follow-up (1–6 months) and long-term follow-up (6–12 months), this effect remained significant and medium in magnitude (0.76 and 0.73, respectively).

“This RCT compared Emotional Awareness and Expression Therapy (EAET) with fibromyalgia education and CBT for symptom management. The 230 patients with fibromyalgia were assessed pre-and post-treatment and the EAET group did better overall than the education group, and had some advantages over CBT in terms of pain relief.”

Our integrative treatment involves delivering a progression of interventions, as needed, to achieve pain reduction: tailored pain neuroscience education, cognitive and mindfulness skills to decrease the pain danger alarm mechanism, behavioral engagement in avoided painful and other feared activities, emotional awareness and expression to reverse emotional avoidance and overcome trauma or psychological conflict, and adaptive communication to decrease interpersonal stress.” Meticulously documented with over 100 references.

Emotional awareness (EA) is a key emotional process that is related to the presence and severity of chronic pain (CP). We describe primary and secondary emotions, discuss the distinction between emotional states and emotional regulation/processing, and summarize theory and research highlighting the significance of EA for CP. We describe ways to assess EA and diagnose centrally-mediated CP, for which emotional processes appear most relevant. We review several psychological interventions designed to enhance EA as well as several broader emotional processing treatments developed to address trauma and psychosocial conflicts underlying many patients’ pain. We conclude by offering our perspective on how future integration of emotional processing into pain care could promote recovery from CP.

Numerous retrospective studies link trauma or posttraumatic stress disorder (PTSD) to Chronic Pain (CP) and prospective studies indicate that earlier trauma is a risk factor for later CP. But current models have rarely informed treatment initiatives, leaving key questions unanswered. How does one define trauma in populations with CP? Is it beneficial to treat comorbid trauma in CP? What interventions effectively do so? This topical review addresses these questions.

A meta-analysis of 25 trials found that when compared with the waiting list control conditions cognitive-behavioural treatments were associated with median effect size across domains = 0.5. Comparison with alternative active treatments revealed that CBT produced significantly greater changes for pain experience, cognitive coping and appraisal (positive coping measures), and reduced behavioural expression of pain. Differences on the following domains were not significant: mood/affect (depression and other, non-depression, measures), cognitive coping and appraisal (negative, e.g. catastrophization), and social role functioning.

Uncontrolled trial of 8 sessions of CBT in 18 adolescents. Headache frequency decreased from 15 ± 7.4 headaches per month before CBT to 10 ± 7.4 after CBT (P < .001). After CBT, greater brain activations in frontal regions involved in cognitive regulation of pain were found as was increased connectivity between the amygdala and frontal regions was observed. Associations between brain activation and amygdalar connectivity with a reduction in headache frequency were also observed.

J. Clin. Med. 2020, 9, 3348; doi:10.3390/jcm9103348
An unblinded but controlled trial in 169 fibromyalgia (FM) patients conducted by a single therapist comparing TAU (treatment as usual: FM education, exercise advice) with a group that received 12 weeks of pain neuroscience education (PNE), cognitive behavioral therapy (CBT), mindfulness and exposure to nature while doing yoga, walking, photography and Shinrin Yoku (forest bathing). Subjects averaged 18 years of
FM with significant comorbidity including chronic fatigue (71%), migraine (50%), irritable bowel (38%), and multiple chemical sensitivity (27%). With an effect size (d) greater than 0.8 considered large, at 12 weeks the treatment effect size on pain was 5.6, on kinesiophobia (fear of movement) 2.2, pain catastrophizing 2.0, on anxiety 1.6, depression 1.4, on physical function 1.4, and fatigue 0.9. The FM impact score (physical dysfunction, life impact, symptom intensity) improved by at least 20% in 67% of treated subjects.

We developed a multidimensional treatment plan by integrating several areas of the literature: collaborative/stepped care, cognitive-behavioral treatment, and the provider-patient relationship. The treatment is designed for primary care personnel (physicians, physician assistants, nurse practitioners) and deployed intensively at the outset; visit intervals are progressively increased as stability and improvement occur.

At six months of follow up, the intervention group reported a higher recovery rate (odds ratio 0.40), a lower mean intensity of the physical symptoms, less impairment of sleep (odds ratio 0.38), lower frequency of the symptoms, fewer limitations in social and leisure activities, and
reduced illness behaviour. At 12 months of follow up, the differences between the groups were largely maintained.

for Chronic Back Pain**.** The Journal of Pain, 2023, ISSN 1526-5900,
https://doi.org/10.1016/j.jpain.2023.04.006.
In a recently published randomized controlled trial (Ashar YK, 2021), two-thirds of the patients receiving pain reprocessing therapy (PRT) reported elimination or near-elimination of chronic back pain. A sample of 32 adults with chronic back pain who received PRT completed semi structured posttreatment interviews about their treatment. 3 major themes reflected
participants’ understanding of how PRT led to pain relief: 1) reappraisal to reduce fear of pain, which included guiding participants to relate to pain as a helpful indicator, overcoming pain related fear and avoidance, and reconceptualizing pain as a “sensation;” 2) the link between pain, emotions, and, stress, which included gaining insight into these connections and resolving difficult emotions; and 3) social connections, which included patient-provider alliance, therapist belief in the treatment model, and peer models of recovery from chronic pain.

“Emotional awareness and expression therapy (EAET) is an emotion-focused therapy for patients with a history of trauma or psychosocial adversity who suffer from centralized pain conditions. In this approach, patients are taught to understand that their pain is exacerbated or maintained by unresolved emotional experiences that influence neural pathways involved in pain. Patients are taught to become aware of these unresolved experiences, which include suppressed or avoided trauma, adversity, and conflict, and to adaptively express their emotions related to these experiences. Patients learn that control over pain can be achieved through emotional awareness and expression. Enhancing the patient’s capacity to approach an experience rather than inhibit or avoid important emotions and interpersonal interactions leads to increased engagement in life activities. Research indicates that EAET has a positive impact on pain intensity, pain interference, and depressive symptoms.” (from p 38)

On average, when compared to no treatment or a non‐psychological treatment, CBT probably reduces pain and distress by small or very small amounts. (M Lumley PhD: On a 0-10 scale the average patient’s pain is 0.4 points better immediately after CBT than after treatment as usual. 6 months later this difference is only 0.2). Compared to a non‐ psychological treatment, CBT probably reduces disability at the end of the treatment by a very small amount on average. Compared to a non‐psychological treatment, CBT may make little to no difference to disability six to 12 months after the treatment.

Fifty-three veterans (mean age = 73.5 years, 92.4% male) with chronic musculoskeletal pain. Patients were randomized to EAET or CBT, each delivered as one 90-minute individual session and eight 90-minute group sessions. 42% of EAET patients had >30% pain reduction, one-third had >50%, and 12.5% had >70%. Only one CBT patient achieved at least 30% pain reduction.

In a review of 71 studies, individuals who reported exposure to trauma were 2.7 (95% CI = 2.3 – 3.1) times more likely to have a functional somatic syndrome. The magnitude of the association with PTSD was significantly larger than with sexual or physical abuse. Chronic fatigue syndrome had a larger association with reported trauma than either irritable bowel syndrome or fibromyalgia.

PTSD symptoms in 746 Danish soldiers were measured on five occasions before, during, and after deployment to Afghanistan identifying six trajectories of change in PTSD symptoms. Two resilient trajectories had low levels across all five times, and a new-onset trajectory started low and showed a marked increase of PTSD symptoms. Three temporary-benefit trajectories showed decreases in PTSD symptoms during (or immediately after) deployment, followed by increases after return from deployment. Predeployment emotional problems and predeployment traumas, especially childhood adversities, were predictors for inclusion in the nonresilient trajectories, showing that factors other than immediately preceding stressors are critical for PTSD development, with childhood adversities being central.

The Positive childhood experiences (PCEs) score asked how often or how much as a child they: (1) felt able to talk to their family about feelings; (2) felt their family stood by them during difficult times; (3) enjoyed participating in community traditions; (4) felt a sense of belonging in high school; (5) felt supported by friends; (6) had at least 2 nonparent adults who took genuine interest in them; and (7) felt safe and protected by an adult in their home. Adult Reported Social & Emotional Support (ARSES) is assessed with “How often do you get the social and emotional support you need?” with five choices Always -> Never. PCEs show dose response decreases in Depression/Poor Mental Health (D/PMH) and increases in ARSES after accounting for exposure to ACEs. The adjusted odds of D/PMH were 72% lower for adults reporting 6 to 7 vs 0 to 2 PCEs. Odds were 50% lower for those reporting 3 to 5 vs 0 to 2 PCEs. Associations were similar in magnitude for adults reporting 1, 2 to 3, or 4 to 8 ACEs. The adjusted odds that adults reported “always” on the ARSES variable were 3.5 times greater for adults with 6 to 7 vs 0 to 2 PCEs. The PCE associations with D/PMH remained stable across each ACEs exposure level when controlling for ARSES. The proactive promotion of PCEs for children may reduce risk for adult D/PMH and promote adult relational health. Joint assessment of PCEs and ACEs may better target needs and interventions and enable a focus on building strengths to promote well-being.

Introducing the hypermnesia–hyperarousal model, which focuses on two psychoneurobiological aspects of the physiology of learning. Threat-induced hypermnesia is meant to make sure that an individual will, in future, recognize a particular danger again, in order to avoid it. Threat-induced hyperexcitability and sensitization are supposed to detect a potential hazard as early as possible. The intense hypermnesia of trauma-associated pain experiences thus becomes the basis for memory-related pain, whereas the trauma-induced hyperexcitability forms the basis for hyperalgesia (heightened sensitivity to pain – ed.) and allodynia (central pain sensitization – ed).”

Post-traumatic stress disorder (PTSD) is associated with both (1) ‘ill-defined’ or ‘medically unexplained’ somatic syndromes, e.g. unexplained dizziness, tinnitus and blurry vision, and syndromes that can be classified as somatoform disorders (DSM-IV-TR); and (2) a range of medical conditions, with a preponderance of cardiovascular, respiratory, musculoskeletal, neurological, and gastrointestinal disorders, diabetes, chronic pain, sleep disorders and other immune-mediated disorders in various studies.

Compared with controls, the patients with chronic pelvic pain showed significantly greater prevalence of lifetime major depression, current major depression, lifetime substance abuse, adult sexual dysfunction, and somatization. They were also 3-fold (64% vs 23%) more likely than controls to have been a victim of childhood or adult sexual abuse. There were no significant differences in either the degree or type of pelvic disease between patients with pelvic pain and controls (affecting
about 1/3 of each group).

Among 43 CFS patients, exposure to childhood trauma was associated with a 3- to 8-fold increased risk for CFS across different trauma types compared to 60 non-fatigued controls. There was a graded relationship between the degree of trauma exposure and CFS risk. Childhood trauma was associated with greater CFS symptom severity and with symptoms of depression, anxiety, and posttraumatic stress disorder. The risk for CFS conveyed by
childhood trauma increased with the presence of concurrent psychopathology.

At age 7 yrs data were collected, by parental report, on physically traumatic events (hospitalisation following a road traffic accident, or for surgery); and factors indicating poor social and psychological environment (periods in local authority care, death of a parent; or parental divorce, alcoholism, or financial hardship). Chronic Widespread Pain was assessed at 45 yrs using self-completion questionnaires. 7571 individuals provided pain data at 45 yrs (71.5%). There was no association between childhood surgery and CWP in adulthood. However, children who had been hospitalised following a road traffic accident experienced a significant increase in the risk of future CWP (relative risk 1.5; 1.05–2.1). Children who had resided in institutional care also experienced an increase in the risk of CWP (1.7; 1.3–2.4) as did those who experienced maternal death (2.0; 1.08–3.7) and familial financial hardship (1.6; 1.3–1.9). Further these associations were not explained by adult psychological distress or social class.

“While other studies have shown that early adversity is a risk factor for later chronic pain, no mechanism for this link has been proposed. The authors propose that since survivors of early adversity have difficulty being aware of and expressing distressing emotions, that physical pain can help them to manage these by competing for attention with them. Paying attention to physical pain is reinforced then, as a way to avoid intolerable emotional pain.”

In a sample of U.S. adults, the two insecure attachment styles (i.e. anxious and avoidant) were positively associated with MUCP. These associations remained statistically significant after adjusting for demographic variables and depressive and anxiety disorders. When the two insecure attachment styles were considered together, only avoidant attachment remained significantly associated with MUCP. Odds of past‐year MUCP increased by 27% for each unit increase (on a 4 point scale) in avoidant attachment. [People with avoidant attachment style see themselves as independent and able to "go it alone." They often maintain strict boundaries, can be emotionally
distant, and have a hard time opening up to their partners or making and keeping close friendships.]

ACE severity was elevated in UCPPS (n = 421) participants compared with healthy
controls (n = 414; p < .001), and was most strongly associated with factors associated with complex chronic pain, including more diffuse pain, comorbid functional symptoms/syndromes, and worse perceived physical well-being (all p < .001). Finally, worse physical well-being mediated the relationship between ACE severity and less likelihood of painful symptom improvement (OR = .871, p = .007)) and a greater likelihood of painful symptom worsening (OR = 1.249, p = .003) at 1 year.

Numerous studies indicate that Black Americans have more severe pain, pain-related disability, and other pain-related outcomes (e.g., disturbed sleep) compared to their White counterparts. We propose that racism is an overlooked but preventable source of, or exacerbating factor for, chronic pain and its consequences, and we advance a framework offering innovative pathways for research, treatment, advocacy, and policy.

findings suggest that enhancement of central sensitization may provide a mechanism
underlying the pain hypersensitivity and chronicity linked to childhood adversity.

adversity are more likely to experience widespread pain as adults.”

Her conclusions include this statement: “There is a strong tendency among those who study and treat pain to view pain as a physical phenomenon that is caused by damage to the body. Nonetheless, years of research have shown that there can be tissue damage with no pain (e.g.,
wounded soldiers in battle) as well as severe pain with no tissue damage (e.g., migraines, fibromyalgia). These dissociations illustrate that, from an experiential perspective, the critical component of painful experience may stem from the mental experience of suffering.”

The most predictive individual factors were (1) job task dissatisfaction and (2) distress as reported on Scale 3 of the MMPI. “This data perhaps explains why the focus on purely physical and injury-related factors has met with little success in dealing with what has become the most expensive orthopedic problem.

In an age-, sex-, and risk factor matched group of asymptomatic individuals, disc herniation had a substantially higher prevalence (76%) than previously reported in an unmatched group. Individuals with minor disc herniations (i.e., protrusion, contained discs) are at a very high risk that their magnetic resonance images are not a causal explanation of pain because a high rate of asymptomatic subjects (63%) had comparable morphologic findings. The only highly significant difference between the pain/sciatica group and asymptomatic control group regarding morphologic findings was the criteria of a nerve root compromise. Work perception and psychosocial factors were helpful in discriminating between symptomatic and asymptomatic disc herniations.

“A prospective study of 67 asymptomatic individuals had MRIs in 1989. 31% had an identifiable abnormality in the spine. Seven years later the investigators looked at these subjects to see how they were doing. The findings on magnetic resonance scans were not predictive of the development or duration of low-back pain. Individuals with the longest duration of low-back pain did not have the greatest degree of anatomical abnormality on the original, 1989 scans.”

The FUTUREPAIN study developed a questionnaire, based on the biopsychosocial model, to predict the probability of developing or maintaining moderate-to-severe chronic pain 7–10 years into the future. From an initial set of 82 variables, a machine learning algorithm derived an 18-variable model tested on a new cohort with sensitivity of .88 and specificity of .76 for future pain. The five items on the questionnaire with the largest coefficients (listed from largest to smallest) were Psychological Distress (Kessler K6), Fair Health, Lost Home, Parental Abuse and Current Chronic Pain.

Women (N = 375) who presented to an inner-city emergency department (ED) with complaints of acute pain were followed up for 3 months. One group (early recovery; n = 93) had recovered to virtually no pain by the initial visit, whereas a second group (delayed recovery; n = 120) recovered to no pain only after 1 month. A third group (no recovery; n = 162) still reported elevated pain at 3 months after the ED visit. The no recovery group reported significantly greater PTSD symptoms, anger, sleep disturbance, and lower social support at the initial visit than both the early recovery and delayed recovery groups.

They did a prospective study of 200 subjects over five years. MRIs were done at the beginning on people with no LBP. They then compared these baselines with MRIs taken during episodes of LBP and find no significant
differences. Most new changes represent progressive age changes not associated with acute events.”

A cohort of 6,015 adults with traffic-related whiplash injuries was assessed. After adjusting for the effect of sociodemographic characteristics, post-crash symptoms and pain, prior health status and collision-related factors, those who expected to get better soon recovered over 3 times as quickly (hazard rate ratio = 3.62, 95% confidence interval 2.55–5.13) as those who expected that they would never get better. Patients’ early expectations for recovery are an important prognostic factor in recovery after whiplash injury and are potentially modifiable by clinicians.

The magnitude of limitations was independently associated with years of education, work status, time spent exercising, catastrophic thinking (PCS-4), and symptoms of depression. They accounted for 50% of variability in physical function, with the major contributor being catastrophic thinking. The model for pain intensity included time spent exercising and fear of painful movement. Anatomic site and radiographic severity of arthritis were not associated with either physical function or pain in our patient sample. This study confirms that limitations and pain from osteoarthritis of the hip and knee are more closely related to personal and psychological factors.

Our study clearly proves that a misinterpretation of the patient’s spinal condition’s status through the MRI report leads to a negative impression of their spine. In a second phase, the authors generated both ‘routine’ and ‘clinical’ reporting for MRIs of 20 chronic LBP patients. Terminologies causing anxiety and fear in Routine Reporting, such as degeneration, tears, fissures, nerve compression, etc., were replaced by alternate terminologies in Clinical Reporting. The effect of Clinical Reporting was significant in orthopaedic surgeons, orthopaedic residents, and physiotherapists as for the same MRI, they perceived lesser severity of the disease, prescribed conservative treatment in more patients, and also assessed lower probability of surgery.

Only 2 drivers reported their worst neck pain lasted more than 3 months. 37 drivers reported no chronic neck pain. These data suggest that demolition derby drivers sustain less chronic neck pain after multiple car collision events than might otherwise be expected.

In this study of 170 patients with LBP with severe Disc or Facet Joint degeneration, no association was found between baseline MRI findings and 13-year disability. This highlights the limited prognostic value of a single baseline MRI scan on long-term disability. None of the MRI changes suggesting degeneration were associated with a worse outcome at 13-year follow-up.

This is an editorial commenting on a study in the same issue that showed that substituting rapid MRI neither saved money nor led to improved clinical outcomes. Rather, the data suggested that substituting rapid MRI increases cost in part because it predisposes patients to undergo surgical
intervention. The author makes the point that there has yet to be any evidence that a structural issue causes back pain. Therefore, “Imaging only serves to bolster the notion that back pain is nothing more than the symptom of an underlying disease. This is a social construct that nurtures an enormous treating enterprise far more than it helps the patient.”

doi: 10.1093/pm/pny154
Twenty-five trials (2,000 participants) were included in the review assessing the effect of invasive procedures over sham. Conditions included low back pain (N.7 trials), arthritis (4), angina (4), abdominal pain (3), endometriosis (3), biliary colic (2), and migraine (2). The risk of any adverse event was significantly higher for invasive procedures (12%) than sham procedures (4%). In the two meta-analysis subsets, the standardized mean difference for reduction of low back pain in seven studies (N.445) was 0.18, and for knee pain in three studies (N.496) it was 0.04. The relative contribution of within-group improvement in sham treatments accounted for 87% of the effect compared with active treatment across all conditions. Conclusions: There is little evidence for the specific efficacy beyond sham for invasive procedures in chronic pain. A moderate amount of evidence does not support the use of invasive procedures as compared with sham procedures for patients with chronic back or knee pain. Given their high cost and safety concerns, more rigorous studies are required before invasive procedures are routinely used for patients with chronic pain.

Investigated the effects of brief (eight contact hours, two weeks of home practice) self
compassion training on pain-related brain processing in chronic low back pain (cLBP). Observed reduced clinical pain intensity and disability (P < 0.01) and increased trait self-compassion and interoceptive awareness (all P < 0.05) following training. Evoked pressure pain response in the right temporo-parietal junction (TPJ) was reduced following training, and decreases were associated with reduced clinical pain intensity. Further, increased fMRI responses to pain anticipation were observed in the right dorsolateral prefrontal cortex (dlPFC) and ventral posterior cingulate cortex (vPCC), and these increases were associated with mean post-training changes in Self-Compassion Scale scores and scores from the body listening subscale of the Multidimensional Assessment of Interoceptive Awareness. These findings, though exploratory and lacking comparison with a control condition, suggest that self-compassion training supports regulation of pain through the involvement of self referential (vPCC), salience-processing (TPJ), and emotion regulatory (dlPFC) brain areas.

mechanisms for both chronic regional and widespread pain.”

Results suggest selective impairments in specific cortico-limbic regions associated with two overlapping circuits, the neuromatrix of pain and the emotion regulation system.

During severe illness, the patient had major psychosocial impairment, high life stress, a low visceral pain threshold, and activation of the midcingulate cortex (MCC), prefrontal area 6/44, and the somatosensory cortex, areas associated with pain intensity encoding. When clinically improved, there was resolution in activation of these 3 areas, and this was associated with psychosocial improvement and an increased threshold to rectal distention.

“A neuroimaging study examined the neural correlates of social exclusion and tested the hypothesis that the brain bases of social pain are similar to those of physical pain. Participants were scanned while playing a virtual ball-tossing game in which they were ultimately excluded. Paralleling results from physical pain studies, the anterior cingulate cortex (ACC) was more active during exclusion than during inclusion and correlated positively with self-reported distress. Right ventral prefrontal cortex (RVPFC) was active during exclusion and correlated negatively with self-reported distress. ACC changes mediated the RVPFC-distress correlation, suggesting that RVPFC regulates the distress of social exclusion by disrupting ACC activity.

who study and treat pain to view pain as a physical phenomenon that is caused by damage to the body. Nonetheless, years of research have shown that there can be tissue damage with no pain (e.g., wounded soldiers in battle) as well as severe pain with no tissue damage (e.g., migraines, fibromyalgia). These dissociations illustrate that, from an experiential perspective, the critical component of painful experience may stem from the mental experience of suffering.”

These findings suggest that pain catastrophizing, independent of the influence of depression, is significantly associated with increased activity in brain areas related to anticipation of pain (medial frontal cortex, cerebellum), attention to pain (dorsal ACC, dorsolateral prefrontal cortex), emotional aspects of pain (claustrum, closely connected to amygdala) and motor control. These results support the hypothesis that catastrophizing influences pain perception through altering attention and anticipation, and heightening emotional responses to pain.

Comparing somatoform pain disorder patients with controls, a pain related hypoactive state of the ventromedial prefrontal/orbitofrontal cortex (BA 10/11) and a hyperactive state of the parahippocampal gyrus, amygdala and anterior insula were found in the patient group. Our findings of an altered cerebral processing of experimentally induced pain in patients with somatoform pain disorder support the hypothesis of dysfunctional pain processing, especially in affect regulating regions.
199. Harper, M. (2012). Taming the amygdala: An EEG analysis of exposure therapy for the traumatized. Traumatology, 18(2), 61-74.
Animal and human studies have shown that the emotional aspects of fear memories
mediated in the lateral nucleus of the amygdala can be extinguished by application of low frequency tetanic stimulation or by repetitive sensory stimulation, such as tapping the cheek. Sensory input creates a remarkable increase in the power of the low-frequency portion of the electroencephalogram (EEG) spectrum. Glutamate receptors on synapses that mediate a fear memory in attention during exposure therapy are depotentiated by these powerful waves of neuronal firings, resulting in disruption of the memory network. In this study nearly all sensory inputs applied to the upper body result in wave power sufficiently large to quench fear–memory networks regardless of input location and type and whether the sensory input is applied unilaterally or bilaterally.

This study looked at how activation in the brain shifts when pain evolves from acute to chronic. We observed that brain activity for back pain in the early, acute/subacute back pain group is limited to regions involved in acute pain, whereas in the chronic back pain group, activity is confined to emotion-related circuitry.

fibromyalgia: functional connectivity of the primary somatosensory cortex is altered by sustained pain and is associated with clinical/autonomic dysfunction. Arthritis Rheumatol, 67, 1395-1405.
Our study demonstrates that both somatic and non-somatic dysfunction in Fibromyalgia, including clinical pain, pain catastrophizing, autonomic dysfunction, and amplified temporal summation, are closely linked with the degree to which evoked deep tissue pain alters S1 connectivity to salience/affective pain‐processing regions. Additionally, diminished connectivity between S1 subregions during the rest phase in FM may result from ongoing widespread clinical pain.
202. Kim SM, Hong JS, Min KJ et al. (2019). Brain Functional Connectivity in Patients with Somatic Symptom Disorder. Psychosomatic Medicine, 81, 313-318*.*
Patients with Somatic Symptom Disorder (SSD) had greater functional connectivity on fMRI study within the sensorimotor network (SMN), default mode network (DMN) and salience network than healthy controls. Patients with SSD also had increased functional connectivity between the SMN and DMN, the SMN and salience network, SMN and dorsal attention network (DAN) and salience network and DAN. This suggests that SSD may be associated with alterations of sensory discriminative processing of pain and other somatic symptoms, which is influenced by affective processing.

“A growing body of evidence suggests that empathy for pain is underpinned by neural structures that are also involved in the direct experience of pain. Meta-analysis of 41 studies that had investigated empathy for pain using fMRI was conducted. The results indicate that a core network consisting of bilateral anterior insular cortex and medial/anterior cingulate cortex is associated with empathy for pain. Activation in these areas overlaps with activation during directly experienced pain, and we link their involvement to representing global feeling states and the guidance of adaptive behavior for both self- and other-related experiences.”

Brain: a journal of neurology*, 126(5): 1079-1091 “Activities in the right and left DLPFC loaded on a separate Principal Component and correlated negatively with perceived intensity and unpleasantness. The inter-regional correlation of midbrain and medial thalamic activity was significantly reduced during high left DLPFC activity,
suggesting that its negative correlation with pain affect may result from dampening of the effective connectivity of the midbrain-medial thalamic pathway. In contrast, right DLPFC activity was associated with a weakened relationship of the anterior insula with both pain intensity and affect. We propose that the DLPFC (dorsolateral prefrontal cortex) exerts active control on pain perception by modulating corticosubcortical and corticocortical pathways.”

“We will discuss the new findings demonstrating the fact that steroids and related mediators produce paradoxical effects on pain such as analgesia, hyperalgesia, and even placebo analgesia. In addition, we will examine the physiologic effect of stress, high allostatic load, and idiopathic disease states such as chronic fatigue syndrome, fibromyalgia, irritable bowel syndrome and burnout. The recently observed positive relationship between glutaminergic activity in the insula and clinical pain will be examined in the context of understanding the central role of steroids in chronic pain.”

The high childhood adversity group showed greater temporal summation of second pain sensitization whereas the low-adversity group showed minimal sensitization. The high adversity group also showed blunted cardiac and skin conductance responses. These
findings suggest that enhancement of central sensitization may provide a mechanism
underlying the pain hypersensitivity and chronicity linked to childhood adversity.

Epub 2006 May 30. “Depression-vulnerable college students (with both elevated prior depressive symptoms and low current depressive symptoms) wrote on 3 consecutive days in either an expressive writing or a control condition. As predicted, participants scoring above the median on the suppression scale of the Emotion Regulation Questionnaire (Gross & John, 2003) showed significantly lower depression symptoms at the 6-month assessment when they wrote in the expressive writing versus the control condition.”

Over a 9 week period, participants in the anger-expression group (n=51) experienced greater improvement in control over pain and depressed mood, and marginally greater improvement in pain severity than the control group (n=51). Degree of expressed anger uniquely accounted for intervention effects and meaning-making mediated effects on depressed mood.

We demonstrate how this approach can benefit physiological reactivity, attention, and performance and explore its potential applications.”

Life stress and the avoidance of negative emotions may contribute to chronic pain. The technique of written or spoken emotional disclosure can reverse emotional avoidance and improve health, and 18 randomized studies have tested it among people with chronic pain. The benefits of emotional disclosure for chronic pain are quite modest overall. Studies in rheumatoid arthritis show very limited effects, but two studies in fibromyalgia suggest that disclosure may be beneficial.

“Somatizers rarely accept a referral for mental health treatment, because they do not experience their pain as psychological in origin. Consultation by psychiatrists or other behavioral health practitioners to the primary care doctor and targeted programs for somatizers that are part of a primary care practice have been shown to pay for themselves and reduce overall medical costs.” “Behavioral health services targeted to chronic pain patients reach enough people and make enough difference in reduced utilization of medical services to more than pay for the cost of the behavioral health services.” “Integrated care describes care that has medical and behavioral health components. The patient perceives care as one treatment plan targeted to his or her needs. Because a PCP is directing the plan, most patients experience it as medical. This is necessary for the very high percentage of patients in primary care who have severe behavioral health needs but would not accept care defined as mental health or psychiatric care.”

Recent studies document an increase in Medicare expenditures of:
• 629% for epidural steroid injections;
• 423% for opioids for back pain;
• 307% for lumbar MRI
• 220% for spinal fusion surgery.
The limited studies available suggest that these increases have not been accompanied by population level improvements in patient outcomes or disability rates.

In 2008, according to the Medical Expenditure Panel Survey (MEPS), about 100 million adults in the United States were affected by chronic pain, including joint pain or arthritis. Using the 2008 MEPS, we estimated 1) the portion of total U.S. health care costs attributable to pain; and 2) the annual costs of pain associated with lower worker productivity. We found that the total costs ranged from $560 to $635 billion in 2010 dollars.

A review of 32 studies from 24 countries published from 1990 – 2012. At least one type of somatoform disorder in 26% to 35% of primary care patients. The percentage of patients complaining of at least one medically unexplained symptom ranged from 40% to 49%.

“Sickness absence is a major public health and economic problem. In 2003, 176 million working days were lost; up 10 million on the previous year. Each week 1 million people report sick, 3000 of whom will still be away from work at six months. Until recently the most common causes were musculoskeletal disorders, in particular low back pain. In 1994-5, 194 000 new awards of social security benefits were made for back related incapacities, accounting for more than one in seven such awards. However, since then awards for back conditions have dropped by 42%.
Over the same decade the contribution of psychiatric disorders to sickness absence has increased markedly, and surveys have shown a doubling in the numbers of people reporting stress that was caused or made worse by their work. Mental and behavioural disorders now account for more incapacity benefit claims than musculoskeletal disorders.”

A total of 567 new complaints of chest pain, fatigue, dizziness, headache, edema, back pain, dyspnea, insomnia, abdominal pain, numbness, impotence, weight loss, cough, and constipation were noted, with 38 percent of the patients reporting at least one symptom. Although diagnostic testing was performed in more than two thirds of the cases, an organic etiology was demonstrated in only 16 percent. The cost of discovering an organic diagnosis was high, particularly for certain symptoms, such as headache ($7,778) and back pain ($7,263). Treatment was provided for only 55 percent of the symptoms and was often ineffective. Where outcome was documented, 164 (53 percent) of 307 symptoms improved. Three favorable prognostic factors were an organic etiology (p = 0.006), a symptom duration of less than four months (p = 0.009), and a history of two or fewer symptoms (p = 0.001).

At baseline in 2019, 40% of participants reported no pain, 39% reported nonchronic pain, and 21% reported chronic pain. Most participants reported the same pain status at both their 2019 baseline report and their 2020 follow-up; for example, 62% of those pain free at baseline remained pain free at follow-up, 54% of those with nonchronic pain in 2019 continued to report nonchronic pain in 2020, and 61% of those with chronic pain at baseline also reported chronic pain at follow-up. Among those pain free in 2019, the 1-year cumulative incidence for chronic pain in 2020 was 6.3%, while the 1- year cumulative incidence for HICP was 1.4%. We also observed evidence for both pain progression and pain recovery. Of those reporting nonchronic pain in 2019, 15% had progressed to chronic pain at follow-up; of those reporting chronic pain in 2019, 10% were pain free in 2020.

BMJ Open Quality 2021;10:e001287. doi:10.1136/bmjoq-2020-001287 Of 306 musculo-skeletal (MSK) MRIs requested by 107 clinicians across 29 practices, only 5% appeared clearly indicated and only 16% received appropriate prior therapy. Most had chronic symptoms and half had psychosocial flags. Mental health was addressed in only 12% of chronic sufferers with psychiatric illness, suggesting a solely pathoanatomical approach to MSK care. Only 8% of all patients were appropriately managed without additional referral. 1.3% of scans revealed diagnoses leading to change in treatment. Most imaged patients received pathoanatomical explanations of their symptoms. Only 17% of results appeared correctly interpreted by GPs, with spurious over-perception of surgical targets in 65% who suffered ‘low value’ (ineffective, harmful or wasteful) post-MRI referral cascades due to misdiagnosis and overdiagnosis. Unfettered musculoskeletal MRI use by General Practitioners has reached unacceptable indication creep and disutility. Only 1–2 patients need to be scanned for one to suffer mismanagement. GP-MSK-MRI fuels unnecessary healthcare utilisation, generating nocebic patient beliefs and expectations, whilst appropriate care is delayed and a high burden of psychosocial barriers to recovery appear neglected.

Although almost all the 222 patients (97.7%) had at least 1 spinal anomaly on imaging, the diagnostic approach estimated that 88.3% of patients had primary (Psychophysiologic) pain, 5.0% had secondary pain, and 6.8% had mixed pain. Patients with primary pain were more likely than the other 2 groups of patients (combined as “non-primary pain”) to report certain functional conditions, central sensitization, and features such as sensitivity to light touch, spreading pain, and pain worsening with stress; however, no difference was detected in depression, anxiety, and catastrophizing between those with primary and nonprimary pain.

These data raise the possibility that both increased health anxiety and number of bothersome somatic symptoms predict frequent medical consultations. A more complex model of predicting future health care is needed than has been studied previously.
