Although the Graston Technique is widely used, the specific impact of application speed on parameters such as muscle stiffness, muscle oxygenation, pressure pain threshold, and pain intensity remains under-investigated. By utilizing a crossover design with a 1-week washout period, this study allows for a precise within-subject comparison of the two speeds.
