Posterior Shoulder TightnessNCT03893994
Effect Of Stretching Programme On Shoulder Performance In Volleyball Players With Posterior Shoulder Tightness
A study testing Stretching exercises in people with Posterior Shoulder Tightness, run by Hacettepe University at 1 site in Turkey (Türkiye).
Trial summary
When the dominant arm is compared with the non-dominant arm in overhead athletes there is a serious internal rotation limitation in the dominant arm. Due to overhead activity, adaptive changes in shoulder joint mobility and flexibility are indicated. Read more about this study

About this study
When the dominant arm is compared with the non-dominant arm in overhead athletes there is a serious internal rotation limitation in the dominant arm. Due to overhead activity, adaptive changes in shoulder joint mobility and flexibility are indicated. Internal rotation limitation is often associated with increased external rotation. One of the reason of this adaptive change is posterior shoulder tightness which is common in overhead athletes as well as in volleyball players. The aim of this study is to determine the effect of stretching program on the range of motion, flexibility of posterior shoulder muscles and functional performance.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Due to overhead activity, adaptive changes in shoulder joint mobility and flexibility are indicated. Internal rotation limitation is often associated with increased external rotation. One of the reason of this adaptive change is posterior shoulder tightness which is common in overhead athletes as well as in volleyball players.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Apr 2020. 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?
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?
Mean change from baseline in shoulder internal ROM measurement with digital inclometery at 6 weeks (time frame: 6 weeks). 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 21 Apr 2020.
