Joint degeneration in the shoulder is not uncommon, but less than weight bearing joints such as the hip and knee. Osteoarthritis in the main ball and socket joint or the acromioclavicular joint typically produces resting pain and stifness with a reduction in joint range of movement. Whilst injection therapy can help relieve inflammation and therefore a degree of pain, it is important to maintain the joints range of movement and muscle strength.
The exercises listed are designed to be performed on a regular basis; little and often being the preferred option. Remember not to over work the shoulder joint. Unfortunately you can can not re-generate your shoulder but with appropriate exercises you can help maintain movement and strength and therefore get the best outcome, despite wear and tear being present.
