Shoulder instability/weakness is a common condition regularly seen by physiotherapists at Farrell Physiotherapy. Your shoulder is a ball and socket joint and is held in place by the surrounding structures including muscles.

What is shoulder instability/weakness?

Shoulder instability happens when the structures surrounding the shoulder joint are weak and therefore do not hold the shoulder in place correctly. If the joint is too loose it may slide partially out of place and this is called shoulder subluxation. If the shoulder joint comes completely out of place this is called dislocation.

What causes shoulder instability/weakness?

Shoulder instability often occurs after a trauma which may partially or fully dislocate the shoulder such as a fall on an outstretched hand or a direct blow to the shoulder and frequently occurs in sports such as rugby.

Shoulder instability can also come on gradually due to repeated stresses to the shoulder joint related to repetitive end range shoulder movements such as swimming or throwing.

Rarely, shoulder instability is caused by a general ligament laxity in the body- commonly referred to as ‘double jointed’.

What are the symptoms of shoulder instability/weakness?

The symptoms over shoulder instability vary from person to person. Some people may experience little or no symptoms and in atraumatic shoulder instability the early symptoms may include the shoulder subluxing or shoulder pain/ache during certain activities.

Post-traumatic shoulder instability is usually reported with a specific and painful incident and often the shoulder will have dislocated or subluxed.

People with shoulder instability often feel a clunking, clicking or popping sensation in their shoulder following certain movements.

How is shoulder instability/weakness diagnosed?

Your physiotherapist can carry out a full shoulder examination to determine whether you have shoulder instability and can rule out other causes of your shoulder problem. Other investigations such as an X-ray or CT scan may also assist in diagnosis and see if any other structures are involved.
