A rotator cuff tear is a common injury that affects the shoulder, specifically the group of muscles and tendons that stabilize the joint. It can cause pain, weakness, and limited mobility, impacting daily activities and range of motion.

Subacromial pain syndrome, also known as shoulder impingement syndrome, is a common condition that causes pain and discomfort in the shoulder. It occurs when the structures in the subacromial space, including the tendons of the rotator cuff, become irritated or compressed.
