Scapula Retraction Exercises in Subacromial Pain Syndrome

Study Overview
=================
Brief Summary
-----------------
Scapula retraction exercises are often recommended as a part of the exercise programs. The primary aim of this study is to investigate the initial effect of the scapula retraction exercises on acromiohumeral distance (AHD) at varying shoulder abduction angles and to compare asymptomatic subjects. The secondary aim of this study is to investigate the effect of scapula retraction exercises on AHD values and symptoms (pain and disability) in patients with SPS.

Detailed Description
-----------------
Subacmial pain syndrome (SPS) is a common cause of shoulder pain and dysfunction in the general population. Exercise interventions is thought as a primary choice in clinical settings. Scapula retraction exercises are commonly recommended as a part of the exercise programs. Applying scapula retraction exercises at varying shoulder abduction angles could restore balance between the scapulothoracic muscles. Since the scapulothoracic muscles dynamically control subacromial space, scapula retraction exercises could further help to maintain AHD during arm elevation. The primary aim of this study is to investigate the initial effect of the scapula retraction exercises on acromiohumeral distance (AHD) at varying shoulder abduction angles and to compare asymptomatic subjects. The secondary aim of this study is to investigate the effect of scapula retraction exercises on AHD values and symptoms (pain and disability) in patients with SPS.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |

| Experimental: Intervention Group<br>exercise program consists of progressive scapula retraction exercises will be applied three times a week total 24 sessions. Home exercise program will also advised two times a day. | Other: Exercise Intervention<br>* Scapula retraction exercises at varying shoulder abduction angles will be applied<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Acromiohumeral Distance (AHD) measurement | Acromiohumeral Distance will be recorded at 0°, 30°, 45°, 60° and 90° of shoulder abduction, and while they are doing scapular retraction with resistive elastic band at each shoulder position. All assessment will be recorded at baseline and at the end of the twelve week rehabilitation sessions | Acromiohumeral distance values will be recorded at baseline and 8-week follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| pain severity | pain severity will be assessed by using 100 millimeters Visual Analogue Scale at rest, at night and during activity. All patients were asked to mark their pain level that corresponds to their pain intensity on the line between 0=no pain and 100=the worst pain imaginable. | pain severity will be recorded at baseline and 8-week follow-up | 
| disability status | disability status will be assessed by using Shoulder Pain and Disability Index (SPADİ). All assessment will be recorded at baseline and at the end of the twelve week treatment sessions. The questionnaire is scored on a 100-point scale, where 0 represents no disabilities and 100 represents extreme disabilities | PADI Score will be recorded at baseline and 8-week follow-up |
