Physical/Self-perceived Performance and 3D Shoulder Kinematics of Volleyball Attackers With/Without Shoulder Complaints and Scapular Dyskinesis

January 5, 2021 updated by: Nuno Morais, Universidade do Porto
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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Asympt. athletes / scapular dyskinesis
Asymptomatic volleyball attackers involved in competitive events ≥ 2 years and with clinical evidence of scapula dyskinesis
Behavioral: Performance measures of the upper extremity
Athletes will perform the unilateral seated shot put test (USSPT) and the upper quarter Y balance test (UQYBT) bilaterally.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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 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.
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)
Time Frame: Through study completion, an average of 1 year
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.
Through study completion, an average of 1 year
Disabilities of the Arm, Shoulder and Hand (sports module)
Time Frame: Through study completion, an average of 1 year
A self-reported measure of upper extremity functioning
Through study completion, an average of 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Side-to-side differences in 3-dimensional scapular angular displacement (in degrees)
Time Frame: Through study completion, an average of 1 year
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.
Through study completion, an average of 1 year
Side-to-side differences in 3-dimensional humerus angular displacement (in degrees)
Time Frame: Through study completion, an average of 1 year
The angular displacement of the humerus in the 3 planes of orientation: plane of elevation, elevation/depression, axial rotation.
Through study completion, an average of 1 year
Side-to-side differences in 3-dimensional thoracic angular displacement (in degrees)
Time Frame: Through study completion, an average of 1 year
The angular displacement of the thorax in the 3 planes of orientation: flexion/extension, lateral rotation (inclination), axial rotation.
Through study completion, an average of 1 year
Side-to-side differences in the upper quarter Y balance test (total excursion, in centimeters)
Time Frame: Through study completion, an average of 1 year
total excursion = sum of the 3 normalized reach distances, in centimeters
Through study completion, an average of 1 year
Visual Numeric Rating Scale score (0-10)
Time Frame: Through study completion, an average of 1 year
A 11-point scale to rate pain intensity
Through study completion, an average of 1 year
Side-to-side differences in the upper quarter Y balance test (overall performance score, in centimeters)
Time Frame: Through study completion, an average of 1 year]
overall performance or composite score = average score of the 3 normalized reach distances, in centimeters.
Through study completion, an average of 1 year]
