COMPARISON OF EFFICACY OF OZONE INJECTION AND DRY NEEDLING IN MYOFASCIAL PAIN SYNDROME INVOLVING TRAPEZIUS; A RANDOMISED CONTROL TRIAL

Abstract

Background: Myofascial pain syndrome (MPS) is a common musculoskeletal disorder 
characterized by presences of multiple myofascial trigger points (MTrPs). In this study, we aim 
to evaluate and compare the efficacy and safety of ozone in MPS with those of the widely used 
dry needling. Methods: This randomised controlled trial was conducted from 16/12/2019 to 
15/12/2020, involving 42 patients with confirmed diagnosis of MPS. They were randomised 
into two groups using simple randomization by sealed envelope method. One group received 
dry-needling (DN) (n= 21) and the other received ozone-injection (OI) (n=21). Both 
interventions were performed once per week for three weeks. The patients were examined 4 
weeks after the last injection.
