Efficacy of Interferential Laser Therapy in Shoulder Pain

Phase 2

Completed

• Conditions: Shoulder Musculoskeletal Disorders

• Registration Number: NCT00694538
• Lead Sponsor: Hospital Universitario Ramon y Cajal

Brief Summary

The purpose of this study is to determine the advantages of the interferential laser therapy in shoulder pain reduction compared with the conventional low level laser therapy modality.

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. Patients diagnosed of shoulder pain from different musculoskeletal disorders will received conventional or interferential laser therapy. This is a comparative, randomized and double - blind clinical study. Two identical equipments of near infrared laser therapy will be used. Number of sessions: 15. Frequency of the sessions: daily. Irradiation technique: manual, contact and punctual.Pain will be evaluated by visual analog scale (VAS) at rest and during analytical shoulder movements (abduction, adduction, internal rotation, external rotation, flexion, extension) and by means of a pain and disability index (SPADI). Evaluations will take place at pre and post treatment.
