The Acute Effects of Different Stretching Techniques

Not Applicable

Completed

• Conditions: Muscle Stretching Exercises; Hamstring Muscles
• Interventions: Behavioral: Static stretching; Behavioral: Mulligan TSLR technique

• Registration Number: NCT04440878
• Lead Sponsor: Yuksek Ihtisas University

Brief Summary

The flexibility of the hamstring muscles is very important and many stretching methods are applied on the hamstring muscles for reducing muscle resistance on movement. The objective of this study was to investigate the acute effects of static stretching and the Mulligan traction straight leg raise (TSLR) technique administered to the hamstring muscles on reducing its resistance to movement by using ultrasound elastography in healthy individuals.

Detailed Description

The study will be included 22 healthy male volunteers. Static stretching will be administered to the hamstring muscles in the first group and the Mulligan TSLR technique will be administered on the same muscle in the second group. Active knee extension angles of the individuals will be evaluated by a digital goniometer and muscle elasticity will be assessed by ultrasound elastography.

Acute effects of Mulligan TSLR on reducing muscle resistance to movement will be evaluated by ultrasound elastography for the first time in this study. In our study, it was planned to examine the acute effects of static stretching and Mulligan TSLR techniques on reducing muscle resistance to movement by ultrasound elastography in healthy individuals with hamstring shortness.
