Abstract

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.
