Overview
Brief Summary
Investigators recent data showed anti-inflammatory effect of Effect of Extracorporeal Shockwave Technology (ESWT). Little studies focused on the effect and pathomechanism of ESWT on shoulder stiffness.
Detailed Description
1. First year:Investigators intend to further delineate the inflammatory mechanism, such as IL-1β, CB1, HSP in the incidence of shoulder stiffness. 2. Second year: Investigators intend to conduct a prospective randomized double-blind study for the clinical effect of ESWT on patients with shoulder stiffness. 3. Third year: Investigators wish to test the biologic effect of ESWT on patients with shoulder stiffness and to elucidate the molecular mechanism for this effect through a randomized comparative study.

Outcomes
Primary Outcomes
the range of motion (ROM) of the shoulder as a measure
Time Frame: 1weeks
Preoperatively, the ROM of the shoulder is measure with the patient in a sitting position. A goniometer is used to measure the angle to which the patient could maximally passively forward flex or abduct the shoulder. External rotation and internal rotation of the shoulders are determined with the patient's arm in a resting position. The investigators assessed shoulder ROM using the SROMD. Normal shoulder ROM without scapular stabilization is considered to be 180° of forward flexion, 180° of abduction, 90° of external rotation, and 90° of internal rotation with the arm at the side. By summation of the measured deficit of ROM, the SROMD is obtained. Patients are defined as having shoulder stiffness if SROMD \>270degrees.
