Action Observation Therapy in Patients Undetgoing Surgery for Shoulder Instability

Study Overview
=================
Brief Summary
-----------------
The study will aim at investigating the effects of action observation therapy (action observation plus motor imagery) in patients with shoulder instability undergoing capsulo-plastic surgery. Forty subjects scheduled for capsulo-plastic surgery will be randomized into an AOT or Control group. AOT group will undergo action observation followed by motor imagery of upper limb motor tasks for 4 weeks after surgery, whereas Control group will perform no intervention. In addition, both groups will undergo postoperative usual care including immobilization with a brace and passive upper limb mobilization. All participants will be assessed for shoulder pain, function, range of motion, fear of movement and quality of life the day before surgery, at training end and 3 months after training end.

| Changes in shoulder function | Disability Arm Shoulder Hand - DASH | At baseline, after 4 weeks of training and at 3 month after the training end | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |

| Changes in shoulder range of motion | Flexion, abduction, inernal and external rotation range of motion assessed using a goniometer | At baseline, after 4 weeks of training and at 3 month after the training end | 
| Changes in fear of movement | Tampa scale of kinesiophobia | At baseline, after 4 weeks of training and at 3 month after the training end | 
| Changes in quality of life | Short Form - 36 items | At baseline, after 4 weeks of training and at 3 month after the training end |
