NCT04440878

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.

Outcome Measures

Primary Outcomes (1)

  • The evaluation of muscle flexibility

    The evaluation of muscle flexibility will be made using the ultrasound elastography method by a radiologist.

    Five minutes after the application

Secondary Outcomes (1)

  • Range of motion (ROM)

    Five minutes after the application

Study Arms (2)

Static stretching

EXPERIMENTAL

Static stretching will be administered to the hamstring muscles in the first group.

Behavioral: Static stretching

Mulligan TSLR technique

EXPERIMENTAL

The Mulligan TSLR technique will be administered on the same muscle in the second group.

Behavioral: Mulligan TSLR technique

Interventions

Static stretchingBEHAVIORAL

Static stretching exercise will be performed under the supervision of a physiotherapist as 30 seconds of stretching and 15 seconds of rest with 10 repetitions, and the individuals will be asked to participate in the exercise actively.

Static stretching
Mulligan TSLR techniqueBEHAVIORAL

Mulligan TSLR will be applied by a physiotherapist in 3 repetitions with the patient in the supine position.
