结局指标
主要结局
Passive range of motion
时间窗: Pre-intervention and post intervention (immediate effect)
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)
Active range of motion
时间窗: Pre-intervention and post intervention (immediate effect)
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)
Muscle stiffness
时间窗: Pre-intervention and post intervention (immediate effect)
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)
Power performance
时间窗: Pre-intervention and post intervention (immediate effect)
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)
次要结局
- Functional performance - Y balance test upper quarter(Pre-intervention and post intervention (immediate effect))
- Functional performance - closed kinetic chain upper extremity stability test (CKCUEST)(Pre-intervention and post intervention (immediate effect))
- Shoulder endurance(Pre-intervention and post intervention (immediate effect))
