Why does rotator cuff tear cause shoulder stiffness?

You may find reaching behind your back, putting on a shirt, or lifting the arm more difficult. Reduced use can make the shoulder feel increasingly restricted. Stiffness can also occur with other shoulder problems, so it does not by itself establish that a tear is present.

Keep the shoulder moving gently within a tolerable range and avoid forcing a sharp or escalating pain. A physiotherapist can select exercises that maintain mobility while respecting the injury. An assessment can also check whether weakness, pain, or another joint issue is limiting movement.

Book an evaluation when stiffness continues, interferes with dressing or sleep, or began after a fall or forceful movement. Get urgent care for a deformed shoulder, a numb or unusually cold arm, or sudden loss of active movement.

Ask which movements are safe, whether supervised mobility work is suitable, and whether your restriction needs imaging or another evaluation.
