What Factors Are Associated With Prognosis of Rotator Cuff Disorder After Subacromial Hyaluronic Acid Injection

Study Overview
=================
Brief Summary
-----------------
To evaluate the correlations between structure of supraspinatus tendon (impingement, tendinopathy or partial tear, as well as full thickness tear) on ultrasonography and its response to subacromial hyaluronic acid injection in rotator cuff disease patients

Detailed Description
-----------------
Objective: To evaluate the correlations between structure of supraspinatus tendon (impingement, tendinopathy or partial tear, as well as full thickness tear) on ultrasonography and its response to subacromial hyaluronic acid injection in rotator cuff disease patients and also investigate the factors associated with clinically important improvement after subdeltoid hyaluronic acid for rotator cuff disorder. Design: Prospective, longitudinal comparison study. Participants: Patients with rotator cuff disease Intervention: Three subacromial injection with hyaluronic acid with 2 week-interval. Main Outcome Measures: Visual analog scale (VAS) of the shoulder pain, Constant score, SPADI score, and angles of active shoulder range of motion (flexion, abduction, external rotation, and internal rotation) at pre-treatment, post-treatment at week 4 and post-treatment at week 12.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| constant shoulder score | the total constant score ranges from 0 to 100 points, with higher scores indicative of better function. The score is divided into four sections: pain, activity of daily living, ROM and the total constant score ranges from 0 to 100 points, with higher scores indicative of better function. The score is divided into four sections: pain, activity of daily living, ROM and strength | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| pain intensity measured by visual analog scale | pain intensity was measured by visual analog scale. the total score ranges from 0 to 10 points, with higher scores indicative of more painful | 0, 6, 12 weeks | 
| Shoulder Pain And disability index | The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that consists of two dimensions, one for pain and the other for functional activities. The pain dimension consists of five questions regarding the severity of an individual's pain. Functional activities are assessed with eight questions designed to measure the degree of difficulty an individual has with various activities of daily living that require upper-extremity use. The SPADI takes 5 to 10 minutes for a patient to complete and is the only reliable and valid region-specific measure for the shoulder. | 0, 6, 12 weeks | 
| glenohumeral joint range of motion | Shoulder flexion, abduction, external rotation and internal rotation were measured with goniometer with patient in supine position | 0, 6, 12 weeks |
