    Review Meta AnalysisThe 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 AnalysisEfficacy 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.
