Sample Book Insights: #1 The incidence of shoulder dysfunction is caused by many variables. Some may result from falls, while others may come from overuse. Shoulder problems can affect the weekend athlete, the office worker hunched over a computer, and the home owner who paints a bedroom wall. #2 The shoulder is a complex joint, and pain can be referred from the neck or other areas of the body, creating different degrees of shoulder problems. The percentage of people experiencing shoulder problems depends on the definition of shoulder pain used. #3 The shoulder is a complex joint that can rock a baby to sleep, hurl a baseball at 90 mph, and generate a 100-mph serve in tennis. However, it is also the most difficult and complicated joint in the body to rehabilitate. #4 The shoulder is made up of four bones: the clavicle, the scapula, the acromion, and the sternum. The joint between the humerus and the scapula is known as the GH joint.
