About this study
Official title: The Acute Effects of Different Hamstring Muscle Stretching Techniques on Reducing Muscle Resistance to Movement by Ultrasound Elastography
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Static stretchingBehavioural
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.
Mulligan TSLR techniqueBehavioural
Mulligan TSLR will be applied by a physiotherapist in 3 repetitions with the patient in the supine position.
| Study group | Role | What they receive |
|---|---|---|
| Static stretching | Experimental | Static stretching will be administered to the hamstring muscles in the first group. Receives: Behavioral: Static stretching |
| Mulligan TSLR technique | Experimental | The Mulligan TSLR technique will be administered on the same muscle in the second group. Receives: Behavioral: Mulligan TSLR technique |
What is being measured
The primary outcome is the main question the study is designed to answer.
The evaluation of muscle flexibility
The evaluation of muscle flexibility will be made using the ultrasound elastography method by a radiologist.
Measured: Five minutes after the application

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The evaluation of muscle flexibility (time frame: Five minutes after the application). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04440878, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Dec 2020; AzTrials last refreshed its copy on 31 Oct 2026.
