Progressive Muscle Relaxation (PMR) Research

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.

This systematic review and meta-analysis assessed the efficacy of progressive muscle relaxation (PMR) training on cancer-related fatigue (CRF) and quality of life (QoL) in patients with cancer. The authors conducted a comprehensive search of PubMed, Embase, Cochrane Library, Web of Science, CINAHL, and other databases for randomized controlled trials.

Seventeen RCTs involving 1,564 cancer patients were included. The pooled analysis demonstrated that PMR significantly reduced cancer-related fatigue (SMD -0.87, 95% CI: -1.17 to -0.57, p < 0.001) and improved quality of life (SMD 0.53, 95% CI: 0.26 to 0.80, p < 0.001) compared to control groups. Subgroup analyses revealed that PMR was effective across different cancer types and treatment phases.

The findings provide strong evidence that PMR is a beneficial complementary therapy for managing fatigue and improving quality of life in cancer patients. The authors recommend incorporating PMR into routine cancer care as a low-cost, non-invasive intervention that patients can practice independently.

This systematic review and meta-analysis evaluated the effects of progressive muscle relaxation (PMR) exercises on sleep quality, anxiety, and depression in patients with COVID-19. The authors searched major databases including PubMed, Cochrane Library, Web of Science, and Scopus for randomized controlled trials examining PMR in COVID-19 patients.

Nine RCTs with a total of 626 participants were included. The meta-analysis found that PMR significantly improved sleep quality (SMD -1.43, 95% CI: -2.37 to -0.49) and reduced anxiety levels (SMD -2.56, 95% CI: -4.21 to -0.91) compared to control groups. However, the effect on depression did not reach statistical significance.

The findings suggest that PMR is a safe, accessible, and effective non-pharmacological intervention for managing the psychological burden of COVID-19, particularly for sleep disturbances and anxiety. The authors recommend integrating PMR into standard care protocols for hospitalized COVID-19 patients.

This systematic review and meta-analysis of 12 RCTs (1,147 cancer patients) examined PMR effects on health-related outcomes. Using Cochrane Risk of Bias 2.0 and GRADE, the study found significant effects on anxiety reduction (SMD = -1.32), pain relief (SMD = -1.02), and quality of life improvement (SMD = 1.65).

This systematic review and meta-analysis examined the efficacy of relaxation therapy, primarily progressive muscle relaxation, as a nursing intervention for post-operative pain relief in patients undergoing abdominal surgery. The authors searched PubMed, Embase, Cochrane Library, and Web of Science for randomized controlled trials.

Eleven RCTs were included in the analysis. The pooled results showed that relaxation therapy significantly reduced post-operative pain intensity as measured by the Visual Analog Scale (WMD -1.27, 95% CI: -1.94 to -0.60, p < 0.001). The intervention also significantly reduced anxiety levels and decreased analgesic consumption compared to standard care. Subgroup analysis indicated that progressive muscle relaxation was the most commonly studied and effective technique.

The findings support the integration of relaxation therapy, particularly PMR, into post-operative nursing care for abdominal surgery patients. As a non-pharmacological, cost-free intervention with no side effects, it provides a valuable complement to standard pain management protocols and can reduce reliance on opioid analgesics.

This systematic review and meta-analysis examined 10 years of research on relaxation training for anxiety. The analysis included 27 studies with various relaxation techniques, with progressive muscle relaxation being the most commonly studied.

Results showed consistent and significant anxiety reduction with relaxation training, with medium to large effect sizes. PMR was effective across different anxiety presentations and populations.

This review examines the evidence for progressive muscle relaxation (PMR) in treating anxiety disorders and explores potential mechanisms of action.

The authors find consistent evidence that PMR reduces anxiety symptoms across multiple disorders including generalized anxiety disorder, panic disorder, and phobias. However, the traditional explanation - that reducing muscle tension reduces anxiety - is challenged by evidence showing cognitive and attentional mechanisms may be equally important.

The review suggests PMR works through multiple pathways including decreased physiological arousal, increased sense of control, and distraction from anxious thoughts.
