Efficacy of Dry Needling Treatment in Myofascial Pain Syndrome

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to investigate the short and long-term effects of dry-needling of participants with trigger points in the upper trapezius muscle. 64 participants who diagnosed with myofascial pain syndrome will be included in the study. All participants will have trigger points in the upper trapezius muscles. They are randomised into two groups: dry needling (n=32) and exercise group (n=32). Ultrasonographic evaluation of trigger points (diameter, circumference and area), pain intensity and neck disability will be evaluated as primary outcome. Active cervical range of motion will be evaluated as secondary outcome.

Detailed Description

Objective: The aim of this study is to investigate the short and long-term effects of dry-needling of participants with trigger points in the upper trapezius muscle. Methods: 64 participants who diagnosed with myofascial pain syndrome will be included in the study. All participants will have trigger points in the upper trapezius muscles. They are randomised into two groups: dry needling (n=32) and exercise group (n=32). Ultrasonographic evaluation of trigger points (diameter, circumference and area), pain intensity and neck disability will be evaluated as primary outcome. Active cervical range of motion will be evaluated as secondary outcome. All treatments will be applied by an investigator and a different blinded investigator will evaluated all participants. Numerical Rating Scale will be used for evaluating pain intensity and Neck Disability Index will be used for evaluating neck disability. Dry-needling treatment will be applied once a week for three weeks. Servical stretching exercises are given to all participants. (20 repetitions in one session and 2 sessions in a day, three days a week.) All participants will be evaluated before treatment, after treatment (at 3rd week) and at 3 month follow-ups.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Dry needling is a technique in which a fine needle is used to penetrate the skin, subcutaneous tissues and muscles to mechanically disrupt tissue without the use of anesthesia. Treatment is often used to treat myofascial trigger points.
Masking: Double
