Rotator cuff dysfunction is typically caused by a combination of factors, including repetitive movements, overuse, and injury. Doing activities that involve repeating the same motions with your arm, like throwing a ball or lifting weights overhead, can strain the rotator cuff muscles and tendons over time. This repetitive strain can lead to inflammation and damage, causing dysfunction.
Overusing your shoulder joint by doing repetitive actions, such as lifting heavy objects or reaching overhead frequently, can also contribute to rotator cuff dysfunction. The constant stress placed on the rotator cuff can weaken the muscles and tendons, leading to dysfunction and pain.
In some cases, rotator cuff dysfunction can be caused by sudden injuries or trauma to the shoulder. Falling or lifting something heavy incorrectly can result in tears or strains in the rotator cuff. These sudden injuries can cause immediate pain and dysfunction in the shoulder.
