Systematic review and meta-analysis of laser physical agent for pain and disability in rotator cuff tendinopathy: subgroup analysis and meta-regression exploration of randomized control trials

Key Points

• The objective is to review the effectiveness of laser therapy for managing pain and disability in rotator cuff tendinopathy.
• Conducted a systematic review and meta-analysis of randomized control trials.
• Analyzed the effects of high-intensity laser therapy (HILT) and low-level laser therapy (LLLT).
• Included subgroup analyses and meta-regression to explore variability in outcomes.
• HILT significantly reduces pain and disability compared to LLLT, which shows limited effects.
• The findings indicate HILT is more effective as either a standalone treatment or an adjunctive therapy.
• Further research is recommended to explore long-term outcomes and establish standardized laser dosing.
