Study population: Athletes from sports organizations involved in competitive events with pain and disability in the shoulder region

Brief 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.

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.

Eligibility criteria: Inclusion Criteria:

* subjects who can perform at least 150 degrees of arm elevation

Exclusion Criteria:

* subjects rating pain ≥8/10
* score 5 on any of the items of the DASH
* pain elicited by provocation maneuvers of the neighboring regions (e.g., cervical spine).

Primary outcomes:
measure: Side-to-side differences in the unilateral seated shot put test (normalized distance thrown, in centimeters)
timeFrame: Through study completion, an average of 1 year
measure: Side-to-side differences in the upper quarter Y balance test (normalized maximal distance reached in each direction, in centimeters)
timeFrame: Through study completion, an average of 1 year
measure: Disabilities of the Arm, Shoulder and Hand (sports module)
timeFrame: Through study completion, an average of 1 year
Secondary outcomes:
measure: Side-to-side differences in 3-dimensional scapular angular displacement (in degrees)
timeFrame: Through study completion, an average of 1 year
measure: Side-to-side differences in 3-dimensional humerus angular displacement (in degrees)
timeFrame: Through study completion, an average of 1 year
measure: Side-to-side differences in 3-dimensional thoracic angular displacement (in degrees)
timeFrame: Through study completion, an average of 1 year
measure: Visual Numeric Rating Scale score (0-10)
timeFrame: Through study completion, an average of 1 year
measure: Side-to-side differences in the upper quarter Y balance test (total excursion, in centimeters)
timeFrame: Through study completion, an average of 1 year
measure: Side-to-side differences in the upper quarter Y balance test (overall performance score, in centimeters)
timeFrame: Through study completion, an average of 1 year]
