Strengthening the Serratus Anterior to Prevent Winging
The Serratus Anterior is that forgotten muscle of the scapulothoracic region. It provides a function of stability and dynamic movement required for normal scapulohumeral rhythm.
When weakened through postural dys-use or injury to the long thoracic nerve it can cause a winging of the scapula. This can be noted with pressing the hands with extended positioning of the elbows into a wall at shoulder height.
