Efficacy of Activator Trigger Point and Shock Wave Therapy on Pain and Function in Active Upper Trapezius Trigger Points: A Randomized Controlled Study

Starting soon · Not applicable

Conditions studied: Cervical

In brief

This study will be conducted as a randomized controlled trial to evaluate the efficacy of trigger point activator and extracorporeal shock wave therapy in patients with active myofascial trigger points in the upper fibers of the trapezius muscle. Participants who meet the inclusion criteria will be recruited and informed consent will be obtained prior to participation. The subjects will then be randomly allocated into two equal groups. Group A: will receive treatment using the trigger point activator applied to the active trigger points of the upper trapezius muscle. Group B: will receive extracorporeal shock wave therapy applied to the same region. The treatment will be applied according to standardized therapeutic parameters for a predetermined number of sessions over the study period. Outcome measures will be assessed before the beginning of the treatment program and after completion of the intervention period. Pain intensity and pressure pain threshold will be assessed using an algometer. Functional disability related to the neck will be evaluated using the Neck Disability Index (NDI). All collected data will be recorded and statistically analyzed to determine the effectiveness of both treatment modalities in reducing pain and improving functional outcomes.
