Shoulder PainNCT02852746
Physical/Self-perceived Performance and 3D Shoulder Kinematics of Volleyball Attackers With/Without Shoulder Complaints and Scapular Dyskinesis
An observational study of Shoulder Pain, run by Universidade do Porto at 3 sites in Portugal.
Trial summary
The study aims to compare the performance and the 3D shoulder kinematics of volleyball attackers with and without scapular dyskinesis and shoulder symptoms in two physical performance measures of the upper extremity, and correlate their outcomes with a self-reported measure of function of the upper extremity.

About this study
The study aims to compare the performance and the 3D shoulder kinematics of volleyball attackers with and without scapular dyskinesis and shoulder symptoms in two physical performance measures of the upper extremity, and correlate their outcomes with a self-reported measure of function of the upper extremity.
Read the detailed description
Volleyball attackers with clinically identified scapular dyskinesis and with/without shoulder symptoms will be compared with respect to performance outcomes and scapular kinematics.
Performance will be assessed by means of the unilateral seated shot put test (USSPT), the upper quarter Y balance test (UQYBT), and Disabilities of the Arm, Shoulder and Hand, sports module (DASH). Pain measurements after completing physical performance measures will be assessed and rated. Relationships between physical (USSPT, UQYBT) and self-perceived (DASH) measures of performance, and with impairment-based measures (clinical measures and 3D shoulder kinematics) will be assessed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Performance measures of the upper extremityBehavioural
Athletes will perform the unilateral seated shot put test (USSPT) and the upper quarter Y balance test (UQYBT) bilaterally.
| Study group | Role | What they receive |
|---|---|---|
| Asympt. athletes / scapular dyskinesis | Asymptomatic volleyball attackers involved in competitive events ≥ 2 years and with clinical evidence of scapula dyskinesis Receives: Behavioral: Performance measures of the upper extremity | |
| Symptom. athletes / scapular dyskinesis | Symptomatic volleyball attackers involved in competitive events ≥ 2 years and with clinical evidence of scapula dyskinesis Receives: Behavioral: Performance measures of the upper extremity |
What is being measured
The primary outcome is the main question the study is designed to answer.
Side-to-side differences in the unilateral seated shot put test (normalized distance thrown, in centimeters)
The unilateral seated shot put test consists of pushing (not throwing) at shoulder height a ~3kg medicine ball as far and forward as possible while keeping the axial skeleton in contact with a wall, knees bent at a right angle, feet flat on the floor, and the non-testing arm resting on the lap.
Measured: Through study completion, an average of 1 year
Side-to-side differences in the upper quarter Y balance test (normalized maximal distance reached in each direction, in centimeters)
The upper quarter Y balance test is performed through the assistance of a testing device (Y-Balance Test Kit), with the subject stabilizing his/her body weight with the upper extremity being tested while performing maximal reaching efforts with the free hand in three directions: medial, superolateral, and inferolateral.
Measured: Through study completion, an average of 1 year
Disabilities of the Arm, Shoulder and Hand (sports module)
A self-reported measure of upper extremity functioning
Measured: Through study completion, an average of 1 year
Secondary outcomes (6)
Side-to-side differences in 3-dimensional scapular angular displacement (in degrees)
The angular displacement of the scapula in the 3 planes of orientation: lateral/medial (upward/downward) rotation, protraction/retraction (internal/external rotation), anterior/posterior tilting.
Measured: Through study completion, an average of 1 year
Side-to-side differences in 3-dimensional humerus angular displacement (in degrees)
The angular displacement of the humerus in the 3 planes of orientation: plane of elevation, elevation/depression, axial rotation.
Measured: Through study completion, an average of 1 year
Side-to-side differences in 3-dimensional thoracic angular displacement (in degrees)
The angular displacement of the thorax in the 3 planes of orientation: flexion/extension, lateral rotation (inclination), axial rotation.
Measured: Through study completion, an average of 1 year
Visual Numeric Rating Scale score (0-10)
A 11-point scale to rate pain intensity
Measured: Through study completion, an average of 1 year
Side-to-side differences in the upper quarter Y balance test (total excursion, in centimeters)
total excursion = sum of the 3 normalized reach distances, in centimeters
Measured: Through study completion, an average of 1 year
Side-to-side differences in the upper quarter Y balance test (overall performance score, in centimeters)
overall performance or composite score = average score of the 3 normalized reach distances, in centimeters.
Measured: Through study completion, an average of 1 year]

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 1 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: status not confirmed, as of the sponsor's last update on 6 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites 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?
Results are not available in the source record.
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?
Side-to-side differences in the unilateral seated shot put test (normalized distance thrown, in centimeters) (time frame: Through study completion, an average of 1 year). 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 6 Jan 2021.
