Static Stretching Exercises and Ultrasound Elastography Evaluation

Not Applicable

Completed

• Conditions: Hamstring Muscle; Elastography; Muscle Stretching Exercise
• Interventions: Other: Mulligan bent leg raise technique; Other: Static stretching exercise

• Registration Number: NCT05981027
• Lead Sponsor: Suleyman Demirel University

Brief Summary

The aim of thid study was to compare two methods applied to increase the flexibility of the hamstring muscles and objectively evaluate changes in muscle stiffness using the two-dimensional shear wave ultrasound elastography (2D SWE) method. Thirty asymptomatic young individuals with hamstring shortness were divided into two groups by simple randomization. The Mulligan bent leg raise (BLR) technique was applied to the first group, and passive static stretching exercises to the second group. Hamstring flexibility was evaluated with the sit-and-reach test, and muscle stiffness with the 2D SWE method.

Arm && Interventions

Group	Intervention	Description
Mulligan bent leg raise technique	Mulligan bent leg raise technique	A single session of 3 repetitions of Mulligan bent leg raise was applied to the participants.
Static stretching exercise	Static stretching exercise	A single session of 5 repetitive stretching exercises was performed on the participants.

Primary Outcome Measures

Name	Time	Method
Back-saver sit-and-reach test	Up to 2 months	The difference between the back-saver sit-and-reach test and the classical sit-and-reach test is that the former is applied unilaterally. The test was administered using the sit-and-reach test box. The participants were asked to sit on a flat surface and rest the sole of one of their feet flat on the end of the box while keeping the other leg flat on the floor by flexing the knee and hips to 90° and 45° sequentially. Maintaining this position, they were asked to place one hand on the other with their palms facing down, slide their hands on the measuring board, slowly reach forward, wait for a second or two at the last point reached

Secondary Outcome Measures

Name	Time	Method
Two-dimensional Shear Wave Elastography	Up to 2 months	All 2D SWE examinations were performed by a specialist radiologist using the Philips EPIQ-7 (EPIQ Elite Diagnostic Ultrasound System Release 7.0.5 Philips) device with an 18-4 MHz linear probe. These measurements were made with the patient lying in the prone position, with the knees in full extension, the ankle at the end of the stretcher, and the feet hanging down. The probe was placed longitudinally in the middle 1/3 of the hamstring muscles. The participants were asked to keep their muscles in a relaxed position, and no extra pressure was applied to the probe to avoid tissue compression that could artificially affect the measured tissue stiffness
