For a patient recovering from an anterior dislocation of the glenohumeral joint, which exercise should be focused on for stabilizing this joint?

1. Stretching of scapular stabilizers

2. Active range of motion of the glenohumeral joint

3. Strengthening shoulder internal and external rotation

4. Strengthening shoulder flexion and horizontal adduction

The correct answer is: Strengthening shoulder internal and external rotation

Focusing on strengthening shoulder internal and external rotation is essential for stabilizing the glenohumeral joint after an anterior dislocation. This is because the rotator cuff muscles, which are crucial for joint stability, are responsible for these movements. Strengthening these muscles helps to provide dynamic stability to the joint, reducing the risk of further dislocations. After an anterior dislocation, the ligaments and structures around the shoulder can be weakened or injured. By specifically targeting internal and external rotation, the patient will enhance the support provided by the rotator cuff, which comprises the supraspinatus, infraspinatus, teres minor, and subscapularis muscles. Improving strength in these areas contributes to better functional control over the shoulder, allowing for a more stable range of motion and reducing the chances of recurrence. It's also important because any exercises focused on improving mobility or flexibility, while beneficial for overall shoulder function, do not directly address the stability concerns that are critical in the early stages of recovery from dislocation.
