Cold pack (15 minutes); pulsed ultrasound therapy (1 watt/cm², 3 MHz, 1:2 pulsed mode; 3 minutes); transcutaneous electrical nerve stimulation (60-120 Hz; 20 minutes) and exercises (20 minutes). The exercises included stretching, strengthening and posture exercises.

PNF in the extremity pattern, were instructed to actively move through the PNF flexion-abduction-external rotation diagonal pattern for 10 repetitions with manual facilitation and the treatment was performed within the range in which pain did not occur. Rhythmic stabilization and repeated contractions were applied from the PNF techniques.

PNF in scapula and upper trunk patterns in addition to PNF in the extremity pattern. The scapular pattern application was performed by positioning the affected extremity in a relaxed position above the stable side in the side-lying position. Rhythmic stabilization and repeated contractions were applied from the anterior-elevation position in the direction of posterior-depression. Extension, lateral flexion and rotation to the affected side were performed in the trunk patterns in rhythmic stabilization and repeated contractions.

The lateral scapular slide test (LSST) was applied to evaluate scapular stability. In the first position (LSST 1), both arms are relaxed at the sides with the glenohumeral joint in a neutral position. In the second position (LSST 2), the subject places both hands on the ipsilateral hips with the humerus in medial rotation in 45° of abduction in the coronal plane. In position 3 (LSST 3), the subject actively extends both elbows and places the upper extremities in a position of maximum medial rotation in 90° of abduction in the coronal plane. The inferomedial angle of the scapula is palpated and marked on both the affected and unaffected sides, and the spinous process of the thoracic vertebra in the same horizontal plane (the reference vertebra) is then marked. The measurements from the reference point on the spine to the medial border of the scapula are measured on both sides in all 3 test positions.

The distance was measured from the sternal notch to the tip of the chin with a tape measure.

The subject stood in a relaxed position with their heels against a wall. The posterolateral acromion was marked and the ruler was held square. The measurement was taken from the acromion to the wall behind the subject to determine the amount of forward displacement.

The gravity-dependent inclinometer (BASELINEᴿ Bubble inclinometer-USA) was used to measure kyphosis. In the first measurement, the inclinometer was placed over the region of the 1st and 2nd thoracic spinous processes and in the second, over the region of the 12th thoracic and 1st lumbar spinous processes. The total of the angles in each measurement was recorded.

Patients' pain will be assessed for three different situations: "at rest", "at activity" and "at night" before and after treatment. The patient is asked to mark the severity of pain on the 10 cm horizontal line [left end(0) = no pain, right end(10)= unbearable pain ]. Data is measured with a standard ruler and results are recorded in centimeters (cm).
