Optimistic Outlook on Shoulder Rotation Exercise
What do you notice when a patient performs shoulder internal and external rotation exercises?
When a patient is lying supine and performing shoulder internal and external rotation exercises, what is a common observation that you might notice?
Explanation:
When observing a patient performing shoulder internal and external rotation exercises, you may notice that their humerus "sticks up" at the end range of motion. This can be attributed to various factors such as incomplete or incorrect superior rotation of the scapula, or potential inflammation or injury to the supraspinatus muscle tendon. The mechanics of the shoulder and scapula play a crucial role in this observation.
During shoulder internal and external rotation exercises, proper movement of the scapula is essential for optimal shoulder function and range of motion. The "sticking up" of the humerus at the end range can indicate a lack of proper scapular rotation, leading to impingement and friction between the humerus and the acromion.
One possible explanation for this observation is incomplete or incorrect superior rotation of the scapula. The scapula should elevate and rotate upward during shoulder movements to prevent impingement of the rotator cuff tendons. If this rotation is not occurring correctly, the humerus may protrude or "stick up" due to the lack of clearance between the acromion and the greater tubercle of the humerus.
In addition, inflammation or injury to the supraspinatus muscle tendon can also contribute to the humerus "sticking up" during shoulder rotation exercises. Increased friction between the tendon and the acromion can result in discomfort and limited range of motion.
It is important to address any observations of the humerus "sticking up" during shoulder rotation exercises to prevent further injury and ensure proper shoulder mechanics. Seeking medical consultation and possibly incorporating corrective exercises can help improve shoulder function and reduce the risk of complications.
