Purpose: This study aimed to evaluate the effects of Low-Level Laser Therapy (LLLT) and Multi-Wave Locked System (MLS) Laser Therapy on clinical and functional parameters in Carpal Tunnel Syndrome. Methods: In the study, 60 patients with mild-moderate carpal tunnel syndrome were evaluated retrospectively in 3 groups. Group I; LLLT, Group II; MLS Laser therapy, Group III; It consisted of patients who did not receive any laser application and were given splints, a home exercise program and patient education. Visual Analogue Scale (VAS), Hand Grip Strength measurement and BOSTON Carpal Tunnel Questionnaire measurements were evaluated from the patients' files at baseline, 4th week and 12th week. Results: Statistically significant improvements were observed in all parameters in Group I and Group II at 4 weeks and 12 weeks compared to baseline. Group III showed no significant differences in grip strength measurements and the BOSTON Functional Status Scale at 4 weeks compared to baseline. The changes between baseline and 4 weeks were statistically significantly better in Group I and Group II compared to Group III for all parameters. No significant difference was found between Group I and Group II in VAS and grip strength improvements, but the improvement in Boston Symptom Severity Scale was significantly more prominent in Group II than in Group I. Conclusion: Both LLLT and MLS Laser Therapy can be considered as conservative treatment options along with splinting and exercise to control the symptoms of Carpal Tunnel Syndrome. MLS Laser Therapy may be superior to LLLT in reducing symptom severity.
