Effects of Myofascial Release and Stretching Technique on Range of Motion and Reaction Time

Abstract

[Purpose] Myofascial release is a manual soft tissue technique that is frequently used in physical therapy, but few reports on the effectiveness of myofascial release are available. We compared the effects of myofascial release and stretching on range of motion, muscle stiffness, and reaction time. [Subjects and Methods] Forty healthy individuals were randomly allocated to four groups: myofascial release for quadriceps; myofascial release for hamstrings; stretch for quadriceps; and controls. [Results] Active range of motion was significantly increased in the two myofascial release groups and the stretch group. Passive range of motion was significantly increased by myofascial release in the quadriceps and stretching groups. No significant differences in muscle stiffness were seen between before and after the interventions. However, premotor time was significantly reduced by myofascial release in the quadriceps and hamstrings groups, with significant differences observed in this parameter between both the quadriceps and hamstrings groups and controls after the interventions. Compared to controls, reaction time was significantly lower after the interventions in the quadriceps and hamstrings groups. [Conclusion] Myofascial release improves not only range of motion, but also ease of movement.
