High-intensity laser therapy markedly improves pain, shoulder function, and abduction range of motion in subacromial impingement syndrome, outperforming conventional therapy.
A recent study has unveiled the prominent benefits of high-intensity laser therapy (HILT) for rehabilitation of subacromial impingement syndrome (SIS)-affected patients. This comprehensive research, encompassing 6 high-quality trials with 284 participants, portrayed HILT as a superior alternative to conventional therapies for alleviating pain and boosting shoulder function.
The goal of this systematic review and meta-analysis was to determine HILT's effectiveness in SIS by identifying, critically appraising, and synthesizing evidence from clinical trials. A comprehensive search of PubMed, Embase, and Scopus (up to March 1, 2024) identified clinical trials comparing HILT with conventional therapy. Two reviewers selected the pertinent studies, extracted data, and examined quality via the Physiotherapy Evidence Database scale.
HILT markedly eased pain both immediately after the intervention (standardized mean difference [SMD] = -1.01, 95% confidence interval [CI] = -1.85 to -0.17) and 3 months later (SMD = -0.51, 95% CI = -0.90 to -0.13). Those treated with HILT experienced better shoulder and arm function, with improvements sustained at 3 months (SMD = 0.45, 95% CI = 0.06 to 0.84). HILT also enhanced shoulder abduction range of motion (SMD = 3.26, 95% CI = 0.49 to 6.03), a critical outcome for SIS recovery.
While no vital differences were noted in shoulder flexion or external rotation range of motion, HILT’s impact on pain and function positions it as a leading choice for SIS. Integrating this innovative therapy into standard practice could boost patient outcomes and set novel benchmarks for musculoskeletal care. Rehabilitation professionals and policymakers are encouraged to recognize HILT as an emerging technology with the potential to achieve superior outcomes compared to conventional standards of care.
