Objectives: To evaluate the therapeutical effects of Multiwave Locked System (MLS^®) laser and the combined therapy of microwave diathermy and interference current, in patients with glenohumeral joint peritendinitis.
Design: This was a prospective, randomised, parallel, single center trial.
Setting: Outpatient Hospital Clinic PARTICIPANTS: A sample of 76 patients with glenohumeral joint peritendinitis.
Methods: The patients were randomized into 2 groups in a 1:1 ratio: a group was treated with MLS^® Laser Therapy (group A) and a group with microwave diathermy and interferential current therapy (group B). The primary outcome was the reduction of pain according to Shoulder Pain and Disability Index (SPADI). Secondary outcomes were improvements of shoulder’s movement (goniometry) and the reduction of pain, through the visual analogue scale (VAS). An intragroup and an intergroup analysis were performed.
Results: Both treatments demonstrated statistically significant intragroup differences. The intergroup analysis showed a greater improvement of MLS^® Laser Therapy in terms of pain reduction at the end of the treatment and at the midterm follow-up visit.
Conclusion: Both therapies have been demonstrated to be effective and safe. The application of MLS^® laser treatment presented more effective and durable therapeutic effects.
