Shoulder Proprioception Following Open and Arthroscopic Instability Repair

Sheba Medical Center45 enrolled

Overview

Shoulder dislocations are common and may result in functionally disabling instability. Disruption of the shoulder capsuloligamentous complex during shoulder dislocation is related to poor proprioceptive and stabilizing capabilities of the joint. It has been demonstrated that surgical restoration of the normal glenohumeral capsular tensioning improves the proprioceptive capability of the shoulder and plays an important roll in restoring shoulder stability. Several studies compared the proprioceptive capabilities of the shoulder between different surgical procedures, however only few have used the "dynamic unrestricted 3-dimensional arm movement model" that has been shown to be more appropriate for assessment of glenohumeral proprioception. To our knowledge, no previous study has compared proprioception measures of the glenohumeral joint following arthroscopic versus open repair for anterior shoulder instability, using the 3-dimensional unrestricted arm movement model.

OBSERVATIONAL

Enrollment

Conditions

Shoulder Proprioception Open Capsular Shift Arthroscopic Bankart Repair Unrestricted Arm Movement

Interventions

The subjects will carry out three dimensional unrestricted arm movements. The subjects' movements will be recorded by optoelectronic infrared cameras and software. Assessment of smoothness parameters of subjects' movements will allow discriminating between subjects with intact or impaired proprioception.
