Background: Myofascial trigger points in the upper trapezius are a common source of neck pain and functional limitation. Conventional myofascial release is widely used, but device-assisted techniques may provide deeper and more consistent mechanical effects, potentially improving clinical outcomes. Objective: To compare the short-term effects of device-assisted versus conventional myofascial release on pain, cervical range of motion, pressure pain threshold, disability, muscle stiffness, and patient satisfaction. Methods: In this randomized controlled trial, 66 participants with upper trapezius trigger points were allocated to either conventional manual myofascial release or device-assisted myofascial release for six sessions over three weeks. Outcomes were measured at baseline and postintervention using VAS, goniometry, algometry, MyotonPRO stiffness assessment, and the Neck Disability Index. Between-group differences were analyzed using ANCOVA, correlations using Pearson coefficients, and predictors of pain reduction using multiple linear regression. Results: Device-assisted myofascial release produced significantly greater reductions in pain (−4.2 vs −3.0), larger improvements in cervical ROM (+14–17° vs +8–10°), higher pressure pain threshold (+2.3 vs +1.4 kg/cm²), greater reductions in disability (−24.6% vs −16.2%), and lower muscle stiffness (p < 0.001). Regression analysis identified device-assisted treatment as an independent predictor of pain reduction (β = 1.18, p < 0.001). Conclusion: Device-assisted myofascial release is superior to conventional manual techniques for short-term management of upper trapezius trigger points.
