Hamstring MuscleNCT04932707
Stretching Exercises on Hamstring Flexibility.
A study testing sub-occipital muscle inhibition technique and Neurodynamic mobilization in people with Hamstring Muscle and Flexibility, run by Cairo University at 1 site in Egypt.
Trial summary
The hamstrings muscles are examples of muscle groups that have a tendency to shorten. Limited flexibility has been shown to predispose a person to several musculoskeletal overuse injuries and significantly affect a person's function. Read more about this study

About this study
Official title: Effect of Adding Suboccipital Muscle Release Versus Neurodynamic Mobilization to Passive Hamstring Stretch in Subjects With Short Hamstring Syndrome.
The hamstrings muscles are examples of muscle groups that have a tendency to shorten.
Limited flexibility has been shown to predispose a person to several musculoskeletal overuse injuries and significantly affect a person's function.
Read the detailed description
The objective of this study will be to compare the effect of three different methods of stretching techniques on the flexibility of hamstring muscle in subjects with short hamstring syndrome.
HYPOTHESES:
There will be no difference between sub-occipital muscle inhibition technique, neuro-dynamic slump stretch, or passive hamstring stretch on hamstring flexibility in subjects with short hamstring syndrome.
RESEARCH QUESTION:
Is there is any difference between suboccipital muscle inhibition technique, neurodynamic slump stretch, or passive hamstring stretch on hamstring flexibility in patients with short hamstring syndrome?
- Conditions
- Hamstring Muscle, Flexibility
- Being tested
- sub-occipital muscle inhibition technique, Neurodynamic mobilization, control (passive stretch exercises)
- Keywords

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
sub-occipital muscle inhibition techniqueOther
this technique will be conducted from a supine lying position. The therapist stretches the suboccipital, placing the hands beneath the patient's head applying pressure up and backward, pressure was maintained till tissue relaxation occurred flexes the head of the patient to get the chin to the manibiurim sternm.
Neurodynamic mobilizationOther
Patient in a comfortable short sitting position at the edge of the bed with the trunk in an military straight position then ask the patient to slump; flex her neck and street the knee joint in complete extension the at the end of the procedure do active dorsiflexion at the tested foot.
control (passive stretch exercises)Other
The patient in a comfortable supine lying position, the patient was asked to flex his hip joint with complete knee extension and ankle in neutral position. The therapist stretches the hamstring of the dominant side

Questions about this trial
What is this clinical trial studying?
A study testing sub-occipital muscle inhibition technique and Neurodynamic mobilization in people with Hamstring Muscle and Flexibility, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 23 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. 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?
knee extension angle test (time frame: Immediately after the procedure). The study lists 2 primary outcomes in all. 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2024.
