About this study
Official title: Acute Effects of Static Stretching Exercises and the Mulligan Bent Leg Raise Technique on Hamstring Muscle Stiffness: an Ultrasound Elastography Evaluation
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.

- Hamstring Muscle, Muscle Stretching Exercise, Elastography

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mulligan bent leg raise techniqueOther
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.
Static stretching exerciseOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Mulligan bent leg raise technique | Experimental | A single session of 3 repetitions of Mulligan bent leg raise was applied to the participants. Receives: Other: Mulligan bent leg raise technique |
| Static stretching exercise | Experimental | A single session of 5 repetitive stretching exercises was performed on the participants. Receives: Other: Static stretching exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Back-saver sit-and-reach test
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
Measured: Up to 2 months
Secondary outcomes (1)
Two-dimensional Shear Wave Elastography
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
Measured: Up to 2 months
