ABSTRACT

AIM: To investigate the effectiveness of dry-needling(DN) together with exercise therapy on pain, ultrasonographic parameters of myofascial trigger points(MTrPs), and upper trapezius(UT) muscles, and neck disability in patients with myofascial pain syndrome.

MATERIAL AND METHODS: This was a single-blind, prospective, randomized, and controlled trial. Participants aged 18-45 years with persistent neck pain for >3 months caused by the active MTrPs in the UT muscles were included. The exercise therapy was performed 3 times/week for 3 months. DN therapy was applied once a week, for a total of three sessions. The pain intensity, ultrasonographic measurements of the thickness of the UT muscle, and diameter of the MTrPs in the UT muscle were the primary outcomes. The secondary outcome was the neck disability.

RESULTS: Seventy participants were randomized into two groups: the dry-needling together with exercise group(DNG, n = 35) and the exercise-only group(EG, n = 35). A total of 8 participants dropped out of the study, and the study was completed with 62 participants(DNG = 33; EG = 29). There was a significant difference in terms of VAS(at night, at rest, and during activity)(p < 0.001) at post-treatment and after 3 months, the thickness of UT muscle(p = 0.004), and diameter of MTrP(p = 0.021) at post-treatment between the groups. No statistical differences were identified in terms of NDI(p = 0.065).

CONCLUSION: This study demonstrated the effects of DN applied together with exercise therapy on reduction of the pain intensity at short(post-treatment) and mid-term(after 3 months), and the ultrasonographic parameters of MTrPs and UT muscles at short-term(post-treatment).
