Effect of Hamstring Stretching on Cervical Flexor Muscle Endurance
A study testing Proprioceptive neuromuscular facilitation in people with Healthy, run by Abant Izzet Baysal University at 1 site in Turkey (Türkiye).
Trial summary
The superficial posterior line is one of the eight main fascial lines defined on the body. One of the important muscle groups on this line is the hamstring muscle group. Studies have shown that various stretching methods applied to the hamstring muscle group affect the cervical region both in terms of range of motion… Read more about this study

About this study
Official title: Acute Effect of Hamstring Stretching Performed With Proprioceptive Neuromuscular Facilitation Technique on the Endurance of Neck Deep Flexor Muscles in Healthy Women
The superficial posterior line is one of the eight main fascial lines defined on the body. One of the important muscle groups on this line is the hamstring muscle group. Studies have shown that various stretching methods applied to the hamstring muscle group affect the cervical region both in terms of range of motion and posture. As a result of this study, it was shown that deep neck flexor endurance increased in women who applied the PNF hold-relax method.

The superficial posterior line is one of the eight main fascial lines defined on the body. One of the important muscle groups on this line is the hamstring muscle group. Studies have shown that various stretching methods applied to the hamstring muscle group affect the cervical region both in terms of range of motion and posture. Our aim in our study is to examine the effect of the proprioceptive neuromuscular stretching (PNF) method applied to the hamstring muscle group on the endura of the deep neck flexors based on these data.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Proprioceptive neuromuscular facilitationOther
The reason for choosing the proprioceptive neuromuscular facilitation technique is that it increases the hip flexion angle more than static stretching. Participants first lay down on the stretcher in a supine position. Then, the participant's lower extremity was lifted straight until the physiotherapist felt resistance. After reaching this position, the participant was asked to try to extend his lower extremity straight with half of his strength. After 10 seconds, the participant was given time to relax and after the participant relaxed, the lower extremity was brought to the new range of motion. This process was applied 3 times.
| Study group | Role | What they receive |
|---|---|---|
| PNF Group | Experimental | In this group participant's hamstring muscles stretched with PNF Receives: Other: Proprioceptive neuromuscular facilitation |
| Control Group | No intervention | No application was made to this group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Deep Neck Flexor Before and After
Deep neck flexor endurance changes before and after PNF hamstring stretch
Measured: Two times in one day (before intervention, immediately after intervention)

Where is the study taking place?
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?
Deep Neck Flexor Before and After (time frame: Two times in one day (before intervention, immediately after intervention)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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?
