Key Takeaway
Systematic review of 46 studies (3,400+ adults) confirms progressive muscle relaxation effectively reduces stress, anxiety, and depression, with enhanced effects when combined with other interventions
Summary
This systematic review synthesized 46 publications from 16 countries covering more than 3,402 adults. Results show PMR is effective in reducing stress, anxiety, and depression. When combined with other interventions, the combined techniques exhibited enhanced efficacy. The review followed PRISMA guidelines and used JBI Critical Appraisal Tools.
Methods
Systematic review searching Scopus, Web of Science, PubMed, PsycINFO, and Cochrane from earliest evidence to March 2023. Included 46 publications from 16 countries with 3,402+ adult participants. Quality assessed using JBI Critical Appraisal Tools. PRISMA guidelines followed.
Key Results
PMR effectively reduces stress, anxiety, and depression across diverse adult populations. Combined PMR with other interventions (e.g., guided imagery, deep breathing) showed enhanced efficacy. Benefits observed in both healthy and clinical populations.

Limitations
Heterogeneity in study designs and outcome measures. Variable PMR protocols across studies. Many studies lacked long-term follow-up. Some studies had small sample sizes. Difficulty in blinding behavioral interventions.
