A comparison of the effects of static stretching and the fascial distortion model (FDM) on hamstring flexibility

Abstract

BACKGROUND: Hamstring flexibility plays a significant role in physiotherapy. Various stretching studies have been conducted to increase hamstring flexibility, but the effects of the Fascial Distortion Model (FDM) on hamstring flexibility have not yet been investigated. Moreover, no studies have compared the effects of FDM and static stretching. OBJECTIVES: To investigate the effects of the FDM on hamstring flexibility compared with static stretching. METHODS: Thirthy healthy adults were divided into two groups: static stretching and FDM groups. Static stretching was performed to hamstring in the supine position. The FDM was performed using trigger band techniques that followed the hamstring in a longitudinal direction. Hamstring flexibility was measured using the active knee extension angle (KEA), passive straight leg raising (SLR), sit-and-reach (SR), and finger-floor distance (FFD) tests. A paired t-test and an independent t-test were performed to compare the hamstring flexibility measurements. RESULTS: Both groups showed significant differences (p< 0.05) in KEA, SLR, SR, and FFD before and after. However, no significant difference (p> 0.05) was found between the two groups. CONCLUSIONS: There was no difference in the effects of FDM and static stretching on hamstring flexibility.
