Comparative Analysis of Dry Needling Techniques for Orofacial Myofascial Pain

In brief

This study aims to compare the clinical effectiveness and individual comfort of three distinct dry needling techniques (dynamic, static, and hybrid) for managing orofacial myofascial pain. Myofascial pain is a highly prevalent manifestation of temporomandibular disorders (TMD), characterized by painful trigger points in the masticatory muscles, such as the masseter and temporalis, which cause pain, muscle tenderness, and jaw movement limitations. While dry needling is widely recognized as an effective minimally invasive therapy to deactivate these trigger points, there is still a lack of consensus in scientific literature regarding the standardization of application protocols. To address this gap, this randomized, triple-blind, parallel-group clinical trial will enroll 45 individuals diagnosed with myofascial pain according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Participants will be randomly allocated into three equal groups (15 individuals per group): Group 1 will receive dynamic dry needling (fanning technique); Group 2 will receive static dry needling (needle kept in situ for 10 minutes); and Group 3 will receive a hybrid approach (combining an initial static period followed by dynamic manipulation). The primary outcome will evaluate changes in self-reported pain intensity using a Visual Analog Scale (VAS) from baseline to 7 days post-intervention. Secondary outcomes will assess changes in pressure pain thresholds (PPT) via digital algometry, mandibular range of motion via digital caliper measurements, and the subjective perception of comfort and acceptability of each technique. Evaluations will be conducted at baseline, immediately post-intervention, at 7 days, and at 15 days of follow-up. The findings are expected to contribute to the standardization of more effective and comfortable clinical protocols for managing orofacial pain.
