Clinical Trial on Frozen Shoulder Using Bilateral Shoulder Radiography in Different Position

Study Overview
=================
Brief Summary
-----------------
This study on frozen shoulder addressed the null hypothesis that there is no difference in the motion of scapula against the thoracic wall between affected and non-affected shoulder.

Detailed Description
-----------------
Adult patients with unilateral shoulder pain lasted for more than one month, accompanied by passive and active limitation of range of motion in all directions will be included. Patients with bilateral involvement, history of trauma, history of surgery on the affected shoulder, history of fracture, shoulder osteoarthritis, symptoms less than one month and any signs of rotator cuff tear will be excluded. MR imaging will be done to exclude other pathologies and frank rotator cuff tear.

Primary Purpose: Diagnostic
Intervention Model: Single Group Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: shoulder radiography<br>Bilateral shoulder AP standard plain x-ray in 0 and 90 degrees of arm abduction. Non-affected shoulder is used to be compared with the affected shoulder. | Radiation: Bilateral shoulder anteroposterior radiography<br>* Patient standing with the tube in front and 105 cm far from the shoulder radiating perpendicular to the cassette in the back, both arms hanging aside the trunk in 0 degrees of arm abduction, 0 degrees of rotation and 0 degrees of extension with the thumb facing forward to obtain true bilateral shoulder anteroposterior view. Voltage and exposure time differs regarding each person's body mass. In the same position, the patient only elevates the arm up to 90 degrees of abduction.<br>|
