Psychological treatments for the management of pain after musculoskeletal injury: a systematic review and meta-analysis.

ABSTRACT: Musculoskeletal injury is a leading cause of pain and disability worldwide; 35% to 75% of people experience persistent pain for months and years after injury. Psychological treatments can reduce pain, functional impairment, and psychological distress but are not widely used after injury. This systematic review and meta-analysis (PROSPERO ID: CRD42021236807) aimed to synthesize the literature testing psychological treatments for pain after musculoskeletal injury. We searched EMBASE, MEDLINE, PubMed, PsycINFO, and CENTRAL from inception to May 2022. We extracted participant, treatment, and injury characteristics and primary (eg, pain intensity, functional impairment, depression, anxiety, and PTSD symptoms) and secondary (treatment feasibility and acceptability) outcomes. Twenty-four randomized controlled trials (N = 1966) were included. Immediately posttreatment, people who received psychological treatments (versus any control) reported lower pain intensity (standardized mean differences [SMD] = -0.25, 95% confidence interval [-0.49, -0.02]), functional impairment (SMD = -0.32 [-0.55, -0.09]), and symptoms of depression (SMD = -0.46 [-0.64, -0.29]), anxiety (SMD = -0.34 [-0.65, -0.04]), and PTSD (SMD = -0.43 [-0.70, -0.15]); at 6-month follow-up, only depression symptoms were significantly lower. Included trials varied widely in treatment and injury characteristics. The certainty of evidence was low or very low for most effects and heterogeneity moderate to substantial. Most studies had risk of bias domains judged to be high or unclear. Owing to very low certainty of results, we are unsure whether psychological therapies reduce pain and functional impairment after musculoskeletal injury; they may result in improved depression immediately posttreatment and at follow-up. More research is needed to identify treatments that result in enduring effects.

Delivery of Exposure and Response Prevention Among Veterans with Obsessive-Compulsive Disorder.

Veterans with obsessive-compulsive disorder (OCD) often face barriers to receiving evidence-based treatments such as exposure and response prevention (ERP). Through retrospective review of electronic medical records, this study examined the rates of ERP delivery in a national sample of 554 veterans newly diagnosed with OCD in the Veterans Health Administration between 2016 and 2017. Results indicated that only 4% of veterans (n = 22) received any ERP treatment; and, of those, 16 veterans received "true ERP." Veterans who received any ERP were younger than those who did not. ERP was primarily delivered by psychologists in urban facilities along the East and West coasts of the USA. The findings from this study emphasize the need to train more providers to effectively deliver ERP in addition to providing telehealth services to increase access to care for veterans in rural areas.

Emotion regulation strategies moderate the impact of negative affect induction on alcohol craving in college drinkers: an experimental paradigm.

Objectives: Observational studies suggest emotion regulation (ER) as a potential treatment target for problematic college drinking. The primary aim of this laboratory study was to determine whether trait ER strategies would moderate the impact of negative affect induction on alcohol craving in college drinkers. Methods: Participants were randomly assigned to a neutral (n = 74) or a negative affect induction (n = 76) and reported their craving after the affect inductions. Results: Greater use of drinking to cope and less use of cognitive reappraisal predicted greater alcohol craving after the negative affect induction, but not after the neutral condition. In contrast, emotion suppression did not predict alcohol craving in either condition. Conclusion: Our results highlight the role of ER tendencies-particularly the benefits of cognitive reappraisal-on alcohol craving when experiencing emotional distress. Therefore, ER strategies may be an important target for college drinkers to prevent and reduce problematic drinking.

Presence of PTSD is Associated with Clinical and Functional Impact in Veterans with Depression Treated in Community-Based Clinics.

Providers in non-traditional mental health settings (e.g., primary care, community medical clinics) face challenges involving patients who often present with multiple mental health conditions, but require rapid assessment and treatment. To help address this challenge, this study characterized differences in health symptom severity and mental health treatment perceptions between depressed Veterans with and without posttraumatic stress disorder (PTSD) served in community medical clinics. Relative to depressed Veterans without PTSD (N = 62), depressed Veterans with PTSD (N = 122) endorsed greater depression, suicidal ideation, anxiety, pain, and insomnia symptoms, as well as lower functioning. Veterans with depression and PTSD also reported greater mental health needs, prior utilization of mental health services, and higher perceived importance of mental health treatment. Results highlight the complexity of comorbid mental health conditions frequently seen in community medical care clinics and suggest that patients with comorbid mental health difficulties may present with a complex array of mental health symptoms.

Perceptions of Telehealth Physical Therapy Among Patients with Chronic Low Back Pain.

Background: Coronavirus disease 2019 prompted the rapid adoption of telehealth to provide physical therapy. Patients' perceptions about telehealth physical therapy are mostly unknown. This study describes perceptions of telehealth physical therapy among patients with chronic low back pain (LBP). Methods: This study surveyed participants in an ongoing multisite clinical trial of nonpharmacological LBP treatments. Participants were asked about their willingness to use telehealth for physical therapy and with other providers and completed the PROMIS-29. Results: Surveys were received from 102 participants (mean age = 48.5 [standard deviation; SD = 11.6]). Thirty-six (35.3%) expressed willingness to receive telehealth physical therapy, 22 were neutral (21.6%), and 44 were unwilling (43.1%). The percentage expressing willingness for telehealth physical therapy was lower than it was for family medicine (p < 0.001) or mental health (p < 0.001). Older (p = 0.049) and Black participants (p = 0.01) more likely expressed willingness to use telehealth for physical therapy. Conclusion: Education and familiarity may help patients view telehealth physical therapy more favorably. Clinical Trial Registration (clinicaltrials.gov NCT03859713).

The Relationship Between Neighborhood Deprivation and Perceived Changes for Pain-Related Experiences Among US Patients with Chronic Low Back Pain During the COVID-19 Pandemic.

OBJECTIVE: Disruptions caused by the COVID-19 pandemic could disproportionately affect the health of vulnerable populations, including patients experiencing persistent health conditions (i.e., chronic pain), along with populations living within deprived, lower socioeconomic areas. The current cross-sectional study characterized relationships between neighborhood deprivation and perceived changes in pain-related experiences during the COVID-19 pandemic (early-September to mid-October 2020) for adult patients (N = 97) with nonspecific chronic low back pain. METHODS: We collected self-report perceived experiences from participants enrolled in an ongoing pragmatic randomized trial across medical centers within the Salt Lake City, Utah and Baltimore, Maryland metropolitans. The Area Deprivation Index (composite of 17 US Census deprivation metrics) reflected neighborhood deprivation based on participants' zip codes. RESULTS: Although those living in the neighborhoods with greater deprivation endorsed significantly poorer physical (pain severity, pain interference, physical functioning), mental (depression, anxiety), and social health during the pandemic, there were no significant differences for perceived changes in pain-related experiences (pain severity, pain interference, sleep quality) between levels of neighborhood deprivation since the onset of the pandemic. However, those in neighborhoods with greater deprivation endorsed disproportionately worse perceived changes in pain coping, social support, and mood since the pandemic. CONCLUSIONS: The current findings offer evidence that changes in pain coping during the pandemic may be disproportionately worse for those living in deprived areas. Considering poorer pain coping may contribute to long-term consequences, the current findings suggest the need for further attention and intervention to reduce the negative effect of the pandemic for such vulnerable populations.

Greater mechanical temporal summation of pain in Latinx-Americans and the role of adverse life experiences.

INTRODUCTION: Adverse life experiences disproportionately impact Latinx-Americans and are related to greater chronic pain rates. However, little is known about how adversities interact with central pain mechanisms for the development of later pain among Latinx-Americans. OBJECTIVES: The current study examined the relationship between adverse life experiences (eg, trauma and ethnic discrimination) and correlates (eg, social status) with mechanical temporal summation of pain (a proxy measure of central sensitization) between pain-free U.S. native Latinx (n = 65) and non-Hispanic White (NHW) (n = 51) adults. METHODS: Participants completed self-report adverse life experience and correlational measures regarding childhood and adulthood and a mechanical temporal summation protocol. RESULTS: Relative to NHWs, Latinx-Americans reported experiencing significantly greater trauma, discrimination, and lower social status during childhood and adulthood, along with greater temporal summation. Contrary to hypotheses, recent and lifetime experiences of ethnic discrimination significantly correlated with less temporal summation among Latinx-Americans. Decreases in objective and subjective social status across the lifespan (childhood to present day) correlated with greater temporal summation for Latinx-Americans. However, r-to-z transformation analyses confirmed that significant adversity and social status correlations observed among the Latinx group did not significantly differ from NHW participants. CONCLUSIONS: The present findings highlight the complex association between adverse experiences, adverse experience risk factors, and pain for Latinx-Americans. Given the disproportion of experienced pain and adversity among Latinx-Americans, the current findings suggest that a better understanding of the unique adversities for this sample may help elucidate the mechanisms underlying the relationship between adversities, adversity correlates, and pain risk for Latinx-Americans.

Using an Adjunctive Treatment to Address Psychological Distress in a National Weight Management Program: Results of an Integrated Pilot Study.

INTRODUCTION: Obesity is highly comorbid with psychological symptoms in veterans, particularly post-traumatic stress disorder (PTSD), depression, and anxiety. Obese veterans with comorbid psychological symptoms often display suboptimal weight loss and poor physical functioning when participating in weight management programs. The MOVE! program aims to increase healthy eating and physical activity to promote weight loss in obese veterans. Adequately addressing psychological barriers is necessary to maximize outcomes in MOVE! for veterans with PTSD, depression, and anxiety. We examined the preliminary outcomes of administering the Healthy Emotions and Improving Health BehavioR Outcomes (HERO) intervention. HERO is adjunctive cognitive-behavioral therapy to MOVE! that addresses PTSD, depression, and anxiety symptom barriers to engagement in physical activity. MATERIALS AND METHODS: All recruitment and study procedures were approved by the institutional review board and research and development committees of the Michael E. DeBakey Veterans Affairs Medical Center and Baylor College of Medicine in Houston, Texas. Participants gave written informed consent before enrollment. Thirty-four obese veterans with a diagnosis of PTSD, depression, and/or anxiety who were attending MOVE! were assigned to the 8-session HERO group or the usual care (UC) group. Veterans completed assessments of PTSD, depression and anxiety symptoms, physical activity, physical functioning, and weight at baseline, 8 and 16 weeks post treatment. Changes from baseline to 8- and 16-week follow-up on the self-report and clinician-rated measures were assessed, using independent samples t-tests and analyses of covariance. RESULTS: At 8 weeks post treatment, participants in the HERO group had significantly higher step counts per day than participants in the UC group. Similarly, at 16 weeks post-treatment, participants in the HERO group continued to experience a significant increase in daily steps taken per day, as well as statistically and clinically significantly lower scores on the depression symptom and PTSD symptom severity. Participants in the HERO group also demonstrated significantly higher scores on the physical functioning inventory than participants in the UC group (44.1 ± 12.1 vs. 35.7 ± 10.7, P = 0.04) at 16 weeks post treatment. CONCLUSIONS: Findings of this small trial have important implications pending replication in a more rigorously designed large-scale study. Providing an adjunctive treatment to MOVE! that addresses psychological distress has potential benefits for psychological symptom reduction, engagement in healthy dietary habits, and greater physical activity for individuals who traditionally experience barriers to making positive weight management changes.

Does Pain Affect Preference? The Effect of Tonic Laboratory Pain on Discounting of Delayed Rewards.

Chronic pain patients show elevated risk behavior on decision-making tasks, as well as increased health risk behaviors (eg, smoking, prescription opioid abuse). Determining pain's effect on underlying cognitive processes that are associated with risk behavior is confounded by comorbidities linked with chronic pain, including depression, anxiety, and substance abuse. Therefore, to understand pain's effect on delay discounting, a behavioral process assessing the extent to which outcomes are devalued as a function of their delay, the present study evaluated the effect of laboratory pain on delay discounting in healthy young adults (N = 85). Using a mixed factorial design, pain (topical capsaicin and warmth) as well as active control (warmth) groups completed a delay discounting task before and during exposure to their respective manipulations. Whereas the pain condition had no effect on delay discounting, participants' pain intensity, unpleasantness, and pain-induced negative valence were associated with less discounting of delayed rewards. However, the effects were very small. PERSPECTIVE: The results suggest that experimental pain may not increase delay discounting, rather sensitivity to pain predicts a very small decrease in discounting of delayed rewards. Although the results are limited to healthy volunteers, this experimental approach allows us to examine the relationship between pain and delay discounting in a controlled manner. Better understanding of pain-related decision-making may lead to improved treatment of health risk behaviors for individuals experiencing pain.
