Telemedicine for Patients with Musculoskeletal Pain Lacks High-Quality Evidence on Delivery Modes and Effectiveness: An Umbrella Review

Abstract

Background: Musculoskeletal (MSK) pain is the leading cause of disability worldwide. Telemedicine is of growing importance, yet impacts on treatment efficacy remain unclear. Objective: This umbrella review (CRD42022298047) examined the effectiveness of telemedicine interventions on pain intensity, disability, psychological function, quality of life, self-efficacy, and adverse events in MSK pain. Methods: PubMed, SPORTDiscus, Cochrane Library, EMBASE, and CINAHL were searched from inception to August 9, 2022, for systematic reviews with meta-analysis, including telemedicine-delivered exercise, education, and psychological interventions, in randomized controlled trials (RCTs). AMSTAR-2 was implemented. Standardized mean differences (SMDs; negative favors telemedicine) were extracted as effect estimates. Results: Of 1,135 records, 20 reviews (RCTs: n = 97, participants: n = 15,872) were included. Pain intensity SMDs were −0.66 to 0.10 for mixed pain (estimates: n = 16), −0.64 to −0.01 for low-back pain (n = 9), −0.31 to −0.15 for osteoarthritis (n = 7), −0.29 for knee pain (n = 1), −0.66 to −0.58 for fibromyalgia (n = 2), −0.16 for back pain (n = 1), and −0.09 for rheumatic disorders (n = 1). Disability SMDs were −0.50 to 0.10 for mixed pain (n = 14), −0.39 to 0.00 for low-back pain (n = 8), −0.41 to −0.04 for osteoarthritis (n = 7), −0.22 for knee pain (n = 1), and −0.56 for fibromyalgia (n = 1). Methodological quality was “critically low” for 17 reviews. Effectiveness tended to favor telemedicine for all secondary outcomes. Conclusions: Primary RCTs are required that compare telemedicine interventions with in-person delivery of the intervention (noninferiority trials), consider safety, assess videoconferencing, and combine different treatment approaches.
