Efficacy of the Interferential Laser Therapy in Pain Reduction in Carpal Tunnel Syndrome

Phase 2

Completed

• Conditions: Carpal Tunnel Syndrome; Neuropathic Pain

• Registration Number: NCT01093209
• Lead Sponsor: Hospital Universitario Ramon y Cajal

Brief Summary

The purpose of this study is to determine the efficacy of the interferential laser therapy in the wrist and hand pain and disability reduction and force improvement in the carpal tunnel syndrome. Subjects are patients diagnosed of carpal tunnel syndrome who have been prescribed laser therapy. Settings: Ramon y Cajal Hospital. Department of Rehabilitation. Physical therapy unit. Electrotherapy section. Occupational Therapy. Department of Neurology.

Detailed Description

The spatiotemporal superposition of two independent and opposite beams of laser generates a constructive interference pattern that increases the therapeutic effects in the irradiated tissue. Patient suffering pain from diagnosed carpal tunnel syndrome will receive conventional or interferential laser therapy. This is a comparative randomized and double blind clinical study. Two identical lasers in near infrared range will be used. Frequency of sessions: daily. Irradiated technique: manual, contact and punctual. Pain will be evaluated by visual analog scale at rest and during analytical wrist movement. Disability will be evaluated by the DASH and BOSTON questionnaire. Evaluation will take place at pre and post-treatment times.
