Effects of Occupational Therapy Intervention on Motor Function, Muscle Strength, and Pain in Adults With Hand...

Area of Science:

• Rehabilitation Medicine
• Occupational Therapy
• Hand Surgery

Background:

• Hand injuries significantly impair motor function, strength, and participation in daily activities.
• Occupational therapy is a common intervention, but its effectiveness requires rigorous evaluation.

Purpose of the Study:

• To systematically evaluate and synthesize evidence on the effectiveness of occupational therapy interventions for improving motor function, muscle strength, and pain in adults with hand injuries.

Main Methods:

• A comprehensive search of seven electronic databases was conducted through May 2025.
• Systematic review and meta-analysis following PRISMA guidelines, including quality assessment of 8 included studies.

Main Results:

• Occupational therapy interventions demonstrated significant improvements in motor function (Hedges' g = 1.53), muscle strength (Hedges' g = 0.40), and pain reduction (Hedges' g = 1.51).
• Effect sizes were large and statistically significant across all measured outcomes.

Conclusions:

• Occupational therapy is an effective intervention for improving motor function, muscle strength, and pain management in adults with hand injuries.
• These findings support occupational therapy's integral role in functional recovery and enhancing independence post-hand injury.
