Rotator cuff exercises to improve shoulder mobility should begin as soon as pain allows. The aim is to restore full, pain free mobility to the shoulder joint. In some patients mobility could already be good depending on how bad their injury is and therefore less time should be spent on these exercises before moving on. Mobility should be done at least once a day and sometimes 2 or 3 times per days is recommended. If any of the exercises are painful do not do them or stay within the pain free range of movement possible.
