Frozen Shoulder is a common cause of shoulder pain, particularly within middle-aged patients. Indeed, in Chinese medicine, Frozen Shoulder is known as ’50-year-old shoulder syndrome’. It is also known as ‘Adhesive Capsulitis’ meaning a ‘Sticky Capsule’ and more recently is coined a ‘Contracted Frozen Shoulder’. It is slightly more common among females than males and is more likely to occur following an injury to the shoulder and is more commonly seen in patients with certain medical conditions such as diabetes. Often there is no cause or explanation for why a Frozen Shoulder occurs.
Typically, Frozen Shoulder often starts slowly, with quite severe pain, often in the upper arm, which then develops into pain with severe stiffness and loss of range of motion at the shoulder region. Patients more often complain that they are having difficulty sleeping due to the pain. The loss of movement most often associated with a frozen shoulder affects the ability for patients to externally rotate their shoulder (turn their shoulder outwards) and therefore patients see a severe restriction of certain movements such as washing their hair or reaching their arm into their coat sleeve.
