Outcome Measures

Primary Outcomes (4)

• Passive range of motion

  Passive range of motion (PROM) testing includes shoulder internal rotation, external rotation, and horizontal adduction. For shoulder internal and external rotation, the subject lies supine on a treatment table with the shoulder abducted to 90° and the elbow flexed to 90°. One examiner stabilizes the humeral head while passively moving the arm, and another examiner measures the range using a goniometer. For shoulder horizontal adduction, the subject lies supine with the shoulder flexed to 90°, the elbow flexed to 90°, and the shoulder internally rotated. One examiner stabilizes the scapula while passively moving the arm, and another examiner measures the range using a goniometer. (unit of measure : degree)

  Pre-intervention and post intervention (immediate effect)

• Active range of motion

  Active range of motion (AROM) testing includes shoulder internal rotation, external rotation, and horizontal adduction. For shoulder internal and external rotation, the subject lies supine on a treatment table with the shoulder abducted to 90° and the elbow flexed to 90°. One examiner stabilizes the humeral head while the subject actively performs the movement, and another examiner measures the range using a goniometer. For shoulder horizontal adduction, the subject lies supine with the shoulder flexed to 90°, the elbow flexed to 90°, and the shoulder internally rotated. One examiner stabilizes the scapula while the subject actively performs the movement, and another examiner measures the range using a goniometer. (unit of measure : degree)

  Pre-intervention and post intervention (immediate effect)

• Muscle stiffness

  The stiffness of the posterior shoulder muscles is assessed using a myotonometer (Myoton-Pro, Myoton AS, Tallinn, Estonia) to measure the infraspinatus and posterior deltoid. During the test, the subject exposes the shoulder area and lies in a prone position. A towel is placed under the front of the shoulder to ensure relaxation. For the infraspinatus, the measurement is taken two finger-widths below the midpoint of the scapular spine. For the posterior deltoid, the measurement is taken two finger-widths from the inferior edge of the acromion. Each muscle is tested five times, and the average value is recorded. (unit of measure : Newton metre)

  Pre-intervention and post intervention (immediate effect)

• Power performance

  Shoulder internal and external rotation strength is assessed with the subject lying supine on a treatment table, with the shoulder abducted to 90° and the elbow flexed to 90°. The subject is instructed to perform a maximal isometric contraction of internal or external rotation for 3 seconds at the highest speed and force possible. One examiner stabilizes the humeral head, while a handheld dynamometer (Kinvent, Montpellier, France) attached to a handle is used for measurement. The test is performed three times, with a 30-second rest between trials, and the average value is recorded. (unit of measure : kilogram and Kilogram Per Second)

  Pre-intervention and post intervention (immediate effect)

  Pre-intervention and post intervention (immediate effect)

• Functional performance - closed kinetic chain upper extremity stability test (CKCUEST)
