Improvement of hand grip strength is a crucial part of hand burn rehabilitation as it is one of the main reflectors of hand function, which in turn reflects general muscle strength. Purpose: To assess the effect of using a Light Emitting Diode (LED) prior to hand grip strengthening exercises. Methodology: Sixty male participants with hand burns were enrolled and randomized into two groups equal in number. Group (A) was exposed to LED for 20 minutes prior to performing hand strengthening exercises in addition to the traditional physical therapy treatment. Group (B) only received traditional physical therapy. Treatment sessions were conducted every other day for a study duration of six weeks. A Standard goniometer and hand grip dynamometer were used to measure Total active motion (TAM) and hand grip strength (HGS) respectively. Results: Both groups showed significant improvements in the measured outcomes. However, there was a significant difference in the mean values of HGS in group (A) compared to that of group (B). Conclusion: LED is a safe and effective modality for improving hand grip strength in 2nd-degree burn victims when applied before hand exercise.
