Shoulder impingement often results from repetitive activities. Weightlifters, tennis players, painters, and construction workers are particularly at risk. However, everyday tasks like driving, reading, working, and cooking can also contribute, as the postures we adopt during these activities can reduce the subacromial space in the shoulder.
The Shoulder
The shoulder consists of three bones connected by muscles and tendons known as the rotator cuff. When the shoulder is raised, the space between the acromion and the rotator cuff narrows, leading to friction that can cause impingement. This condition can make it painful to lift your arm overhead or put on a coat, and if left untreated, it may result in a rotator cuff tear. Maintaining good posture is crucial in preventing shoulder impingement.
How Good Posture Prevents Shoulder Impingement
Proper posture ensures the shoulder blade remains aligned, promoting a healthy scapulohumeral rhythm. It also keeps the muscles around the upper back, shoulders, and chest flexible, preventing the tightening of the trapezius muscle. Poor posture can lead to muscle imbalances that may cause injury or pain over time.
Tips for Maintaining Good Posture
Achieving good posture while sitting, standing, and sleeping is essential for optimal body function and the prevention of shoulder impingement. Here are some guidelines:
