What is an outcome of abnormal scapular positioning during shoulder movements?

Abnormal scapular positioning during shoulder movements can lead to an increased risk of impingement. This occurs because the scapula plays a crucial role in shoulder mechanics. Proper positioning of the scapula allows for optimal alignment and movement of the humerus during shoulder activities. When the scapula is not positioned correctly, it can result in the humerus colliding with surrounding structures, such as the acromion, leading to impingement of the shoulder tendons and bursa.

Impingement syndrome often manifests as pain, restricted movement, and can significantly impact an individual's ability to perform everyday tasks. Maintaining proper scapular mechanics is essential for shoulder health, as it directly influences the biomechanical function and efficiency of the shoulder joint during movements.

In contrast, improved shoulder stability, increased range of motion, and better muscle coordination typically result from correct scapular positioning and mechanics. Thus, the connection between abnormal scapular positioning and the increased risk of impingement is a vital concept in shoulder rehabilitation and post-operative management.
