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.

Conditions

• Hamstring Muscle
• Muscle Stretching Exercise
• Elastography

Interventions

Type	Name	Description
OTHER	Mulligan bent leg raise technique	In this study, while the participant was lying on his back on a high bed, the physiotherapist sat on the lateral side of the leg to be treated, placing the popliteal fossa of the participant's knee on his shoulder. The hip and knee of the leg to be stretched were placed in 90° flexion. Distraction was applied to the lower end of the femur, and the participant was asked to push the physiotherapist's shoulder with his leg and then relax. At this relaxation point, the physiotherapist pushed the flexed knee as far as possible in the direction of the ipsilateral shoulder in a painless range.
OTHER	Static stretching exercise	The participant lay on a stretcher in the supine position with his back straight. The physiotherapist placed the participant's leg on his shoulder with the knee in full extension and supported by the ankle and flexed the hip as much as possible until a tension was felt in the posterior thigh. This position was maintained for 30 seconds.
