It is very common for people with arthritis to have stiff joints. This is secondary to the cycle that occurs when they avoid movement because it is painful. By not moving the arthritic joint, the pain and stiffness actually get worse making it more difficult to get around.
People with arthritis often benefit from physical therapy, because we encourage increased movement of the joint by working out the stiffness and then focus to help build strength around the joint. The strengthening helps prevent further damage from occurring.
