Abstract
The purpose of this placebo-controlled study was to investigate the therapeutic effects of 830nm diode laser for treating transverse carpal ligament (TCL) in carpal tunnel syndrome (CTS). Methods: Twenty-eight cases of mild-to-moderate carpal tunnel syndrome were randomly divided into two groups. The cases in the laser group received actual laser treatment (10Hz, 60mW, 9.7J/cm^2, 830nm) while the placebo group received sham laser treatment (without laser output). Both groups were treated five times per week for two weeks and were reexamined after two weeks. In each patient, the therapeutic effects were measured by nerve conduction study (NCS), visual analogue scale, and physical examination (Phalen sign and Tinel' sign). Results: After the two-week treatment, both mild and moderate CTS groups had significantly reduced pain scores (p＜0.05). However, only the mild CTS group retained the change two weeks after the treatment. In NCS and physical examination, only subjects with mild CTS in laser group revealed statistically significant improvement after the two-week treatment (p＜0.05).Conclusions: Low-level laser applied on TCL improves pain and neurological symptoms in mild CTS patients.
