Abstract

Background: This quantification process is made through electromyography analysis. This technique of analysis is able to provide a general view of the tension decrease in the superior muscle fibers of the trapezius after therapy.

Aims: The focus of the present work is to evaluate the treatment of the cervicobrachialgia by Positional Release Therapy (PRT).

Material and methods: The present work studies six patients, with ages 44 to 63 (1 male and 5 female) who present tension in the trapezius upper portion fibers. All patients were submitted to 10 session of 30 minutes each. The electromyography was collected on the first and tenth day of treatment.

Results: The results demonstrated a progressive decrease of pain in each session. The tension was evaluated by the electromyography analysis, which showed the relations between time of treatment and less pain.

Conclusion: With these results, it was possible to verify quantitatively the efficiency of the PRT in the improvement of life quality.

Keywords: Trapezius upper portion; electromyography; muscle tension; positional release therapy.
