About this study
The goal of this study is to explore the intervention effect of home-based neurodynamic slider program on hamstring flexibility. Fifty physically active male subjects will be randomly assigned to either performing a neurodynamic sliding technique (3x20 reps) or a static stretching protocol (3x30") on a daily basis for a 6-week period. Hamstring flexibility will be assessed by means of the Straight Leg Raise at baseline, immediately after the intervention and after 4 weeks follow up.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NeurodynamicsOther
Subjects in the neurodynamic group performed the 'Seated Straight Leg Slider' (SSLS) (Fig.1). To execute this sliding technique, subjects assumed a seated slump position (thoracic and lumbar flexion) which they needed to maintain throughout the exercise. This SSLS consisted of alternating movements towards knee extension and ankle dorsiflexion (increase of neural tension) combined with cervical extension (decrease of neural tension) on one hand, and knee flexion and ankle plantar flexion (decrease neural tension) combined with cervical flexion (increase of neural tension) on the other. During this 6-week period, each subject in this neurodynamic slider group was instructed to perform 3 sets of 20 repetitions on a daily basis for 6 weeks.
Static stretchOther
Subjects in the control group were instructed to perform a standard standing static stretch with the heel of the dominant leg taking support on a chair. Then they had to move the pelvis into anteversion, simultaneously inducing a forward lean of the trunk, until the clear sensation of hamstring stretch was perceived at the posterior aspect of the thigh. Again, the execution of the exercise was thoroughly explained and evaluated by the researchers and subjects sent home with a comprehensive instruction guide and supporting pictures. Each subject was instructed to do 3 repetitions of 30 second static stretches on a daily basis during the 6-week intervention.

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 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.
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?
Hamstring flexibility (time frame: at Baseline). The study lists 3 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 15 Dec 2022.
