Therapeutic Effects of Low-Level Laser Combined with LED on Post-operative Hand

Purpose: This study was performed to identify and investigate the therapeutic effects of low-level laser (LLL) combined with a lightemitting diode (LED) on post-operative wound healing and functional recovery after hand orthopedic surgery.Methods: The study subjects were twenty patients who had passed the acute inflammatory phase after hand orthopedic surgery and were assigned equally to an experimental or a control group.Phototherapy was administered three times weekly for two weeks.Changes in wound length, edema, pain, and hand function were measured.Results: Significant differences in wound length, edema, pain, and hand function were observed between the experimental and control groups (p< 0.05).However, no significant intergroup difference was observed (p> 0.05).Nonetheless, a comparison of results showed changes in the experiment group over the two-week study period were significantly greater than in the control group (p< 0.05).Conclusion: These findings show that combined LLL plus LED phototherapy positively influences post-operative hand rehabilitation.
