About this study
Official title: Acute Effects of Static Stretching on the Shoulder Joint Position Sense of Overhead Athletes: a Randomized Crossover Trial
The purpose of the study is to investigate the acute effects of static stretching on the shoulder joint position sense of overhead athletes.
Read the detailed description
A crossover randomized controlled trial will be conducted with 17 overhead athletes (9 males and 8 females). All of them will perform the 3 study conditions in random order: a control (5-minute rest), and static stretching of 30 or 90 seconds of muscles around the shoulder. The shoulder joint position sense will be assessed before and immediately after these conditions, and tested by active repositioning for the range of 110º of flexion, with a video camera. Absolute, relative and variable angular errors will be calculated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Static StretchingOther
- Shoulder extension - shoulder extension with the hand resting on a door;
- Doorway stretch - horizontal abduction with the shoulder in 90º of abduction, the elbow in 90º of flexion and the forearm leaning against a door;
- Shoulder flexion - arms above the head against a wall;
- Cross-body stretch - maximal horizontal adduction of the arm, with the opposite hand holding the stretch;
- Overhead triceps - arm above the head and elbow flexed, with the other hand pulling the elbow;
- Internal Rotation 90° stretch - with the shoulder at 90º of flexion and the elbow at 90º of flexion, the opposite hand and forearm forces the internal rotation.

What is being measured
The primary outcome is the main question the study is designed to answer.
Absolute angular error
The absolute value of the difference between the target range and the achieved range
Measured: Change from Baseline (Before) to Immediately after interventions or control (After)
Relative angular error
The arithmetic difference between the target range and the range achieved
Measured: Change from Baseline (Before) to Immediately after interventions or control (After)
Variable angular error
The standard deviation of the 3 repositionings
Measured: Change from Baseline (Before) to Immediately after interventions or control (After)

Questions about this trial
What is this clinical trial studying?
A study testing Static Stretching in people with Healthy, run by University Fernando Pessoa at 1 site in Portugal.
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 2 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 21 Feb 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 Portugal. 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?
Absolute angular error (time frame: Change from Baseline (Before) to Immediately after interventions or control (After)). 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 21 Feb 2024.
