About this study
Official title: Effects of Foam Roller Application Prior to Proprioceptive Neuromuscular Facilitation Stretching on Hamstring Flexibility and Thigh Skin Temperature in Healthy Subjects
There is no study investigating the hamstring flexibility and skin temperature after combined warm-up techniques especially PNF and foam rolling. The main purpose of this study is to investigate the effects of foam roller application prior to proprioceptive neuromuscular facilitation stretching on hamstring flexibility and thigh skin temperature in healthy subjects.Secondly, it is aimed to compare the effects between non-vibration foam rolling and vibration foam rolling on measured parameters.
Read the detailed description
In this study forty-eight subjects will be voluntarily recruited into the study according to inclusion criteria. Participants will be randomly assigned to Vibration Foam Rolling + PNF stretching, Non-Vibration Foam Rolling + PNF stretching, only PNF stretching and control group. Subjects will be evaluated before, immediately after and 30 minutes after intervention. Hamstring flexibility will be evaluated with Active Knee Extension Angle (AKEA) Test and functionally Sit and Reach test. Thigh skin temperature will be evaluated with thermographic imaging.

Non-vibration foam rolling prior to PNF stretchingOther
Prior to PNF stretching, participant will perform unilateral hamstring non-vibration foam rolling.
Vibration foam rolling prior to PNF stretchingOther
Prior to PNF stretching, participant will perform unilateral hamstring vibration foam rolling (48 Hz).

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in hamstring flexibility
Active Knee Extension test in supine position will be performed to measure hamstring flexibility.
Measured: Change from baseline hamstring flexibility at immediately after intervention and 30 minutes after intervention

Posterior thigh skin temperature will be evaluated using thermographic imaging with infrared thermal camera.
Measured: Change from baseline skin temperature at immediately after intervention and 30 minutes after intervention
Change in functional hamstring flexibility
Sit-and-Reach test will be performed to measure functional hamstring flexibility.
Measured: Change from baseline functional hamstring flexibility at immediately after intervention and 30 minutes after intervention

Questions about this trial
What is this clinical trial studying?
A study testing PNF stretching, Non-vibration foam rolling prior to PNF stretching and Vibration foam rolling prior to PNF stretching in people with Healthy, run by Dokuz Eylul University at 1 site in Turkey (Türkiye).
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 5 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: status not confirmed, as of the sponsor's last update on 2 Feb 2021. 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 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sinem Yenil (00904124924, sinemyenil_96@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in hamstring flexibility (time frame: Change from baseline hamstring flexibility at immediately after intervention and 30 minutes after intervention). 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 2 Feb 2021.
