Joint dislocation occurs when a joint separates or dislocates abnormally disrupting the normal alignment of a joint. Joints may also sublux and this occurs when the joint begins to dislocate but has not yet lost contact on two sides of the joint. Dislocations occur commonly in the shoulder and finger joints. Physical Therapy can help identify tight and weakened muscles around the joint and design exercises to help promote balance and teach joint protection strategies and proper posture.
