Our shoulders are one of the most versatile and incredible joints in the human body. The shoulder is a “ball and socket joint” and allows for the most range of motion and mobility of any joint in the body. The shoulder requires that at least 12 muscles work together at any given time along with the scapula and humerus of the arm in order to allow for optimal shoulder motion and function. Because of the large range of motion our shoulders allow, it is often times not as stable as our other joints and can frequently become injured. Right now we are specifically looking at how we can improve our shoulder mobility and stability, in order to ensure optimal shoulder performance.
The Apley’s Scratch Test and the Seated Shoulder Flexion Test are two self examination screens you can perform on yourself to determine if you have adequate mobility at the shoulder.
