Review Meta Analysis
The prevalence, characteristics and impact of chronic pain in people with muscular dystrophies: A systematic review and meta-analysis.
Chronic pain is a frequent, yet under-recognized and under-assessed problem in people with muscular dystrophies (MDs). Knowledge of the prevalence and characteristics of chronic pain, and its impact on function and quality of life is limited and lacks systematic exploration. This article aims to systematically review and synthesize existing literature that addresses chronic pain prevalence, characteristics and impact in people with different types of MDs. ⋯ The protocol for this review has been published on PROSPERO (CRD42020168096). PERSPECTIVES: This is the first systematic review and meta-analysis exploring the prevalence, and nature and impact of chronic pain in people with MDs. The present study demonstrates how common chronic pain is across various MD populations and highlights the need for better recognition and understanding of the nature and impact of pain from health professionals.

Review Meta Analysis
Efficacy of online-based Acceptance and Commitment Therapy for chronic pain: A systematic review and meta-analysis.
Acceptance and Commitment Therapy (ACT) has been widely tested for chronic pain, with demonstrated efficacy. Nevertheless, although there is meta-analytical evidence on the efficacy of face-to-face ACT, no reviews have been performed on online ACT in this population. The aim of this meta-analysis is to determine the efficacy of online ACT for adults with chronic pain, when compared with controls. ⋯ PERSPECTIVE: This is the first meta-analytical review on the efficacy of online ACT for people with chronic pain. It comprises 5 RCTs that compared online ACT with active and/or inactive controls. Online ACT was more efficacious than controls regarding pain interference, pain intensity, depression, anxiety, mindfulness, and psychological flexibility.

Randomized Controlled Trial
The Effect of Literacy-Adapted Psychosocial Treatments on Biomedical and Biopsychosocial Pain Conceptualization.
This is a secondary data analysis of a subgroup of participants who received the Learning About My Pain (LAMP) intervention (clinicaltrials.gov identifier NCT01967342). We examined the effects of LAMP on pre-to-post changes in biomedical and biopsychosocial pain conceptualization and whether those changes in pain conceptualization were associated with physical and psychological functioning. Participants were randomized into three conditions: Cognitive Behavioral Therapy (CBT), Pain Psychoeducation (EDU), or Usual Medical Care (UC). ⋯ Overall, results of this study suggest the need for targeting specific pain beliefs that influence pain-related outcomes. PERSPECTIVE: This article presents the potential benefits of providing literacy-adapted psychosocial treatments to expand pain conceptualization beyond a biomedical-only understanding and toward a biopsychosocial conceptualization of the experience of pain. Furthermore, the association of changes in pain conceptualization and pain-related functioning argues for its potential clinical relevance.

Randomized Controlled Trial
Opioid specific effects on central processing of sensation and pain: a randomized, cross-over, placebo-controlled study.
Moderate to severe pain is often treated with opioids, but central mechanisms underlying opioid analgesia are poorly understood. Findings thus far have been contradictory and none could infer opioid specific effects. This placebo-controlled, randomized, 2-way cross-over, double-blinded study aimed to explore opioid specific effects on central processing of external stimuli. ⋯ Due to the strong correlations with pain relief, the changes in EEG signals during cold-pressor test have the potential to serve as biomarkers of opioid analgesia. PERSPECTIVE: This exploratory study presents evidence of opioid specific effects on the pain system at peripheral and central levels. The findings give insights into which measures are the most sensitive for assessing opioid-specific effects.

The Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale ("B-CRPS-BPDS") measures alterations in body perception. We assessed its internal consistency, known group validity, construct validity, and associations with demographic and clinical characteristics. We also evaluated changes in, and baseline predictors of B-CRPS-BPDS scores at follow-up. ⋯ Our results demonstrate the utility of the r-B-CRPS-BPDS for measuring body perception disturbances in CRPS. PERSPECTIVE: This article evaluates the validity of the Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale ("B-CRPS-BPDS") in CRPS, and assesses relationships with demographic and clinical variables. The proposed revised B-CRPS-BPDS appears to be a valid measure of body perception disturbances in CRPS.
