The long-term changes that occur in and around the shoulder joint as a result of everyday wear and tear cannot be totally prevented. But you may be able to prevent some rotator cuff disorders by:

• Keeping the muscles in your shoulders flexible and strong. Daily exercises to maintain strength and flexibility may be the best defense against rotator cuff disorders.
• Keeping good posture at all times. Stand straight and relaxed, without slumping.
• Not lifting objects that are too heavy for you, especially not over your head.
• Not catching falling objects.
• Avoiding sports or other activities where forceful contact or falls are likely or common.
• Not keeping your arms out to the side or raised over your head for long periods of time, such as when painting a ceiling. If you must do these activities, take frequent breaks, ice your shoulder several times a day and at night, and take a nonsteroidal anti-inflammatory drug to relieve any swelling and pain in the tissues that are being pinched. Ask your doctor if it would be helpful to take an anti-inflammatory medicine before activities that may stress your shoulder.
