The shoulder joint is one of the most complicated moving parts of the body and has one of the widest ranges of movement – second only to the thumb. The shoulder is classed as a multiaxial joint as the arm can move in more than two planes: up and down, backward and forward, as well as being able to rotate in a circle at the side of the body. This wide range of movement is stabilised by the collar bone and by a complex system of ligaments and rotator cuff muscles.
Friction is reduced by several sacs (bursae) which contain lubricating synovial fluid. In order to achieve such a wide range of movement, the head of the humerus is larger than the socket into which it fits, and the joint capsule is relatively lax. This makes the shoulder joint inherently unstable.
Shoulder pain is often due to ‘overuse’ and strain which can inflame the tendons of the rotator cuff muscles. Frozen shoulder is also a common cause of pain, stiffness and immobility of the shoulder joint. This is due to inflammation and thickening in the lining of the capsule surrounding the joint (capsulitis). In most cases, no obvious cause is found, but it may come on after a fall, a task involving repetitive movements of the joint (for example, painting a ceiling) or after unaccustomed exercise.
There is growing interest in the use of magnetic therapy as a non-invasive way to reduce pain and improve mobility in musculoskeletal conditions.
“I have used magnetic therapy for over twenty years, and found personal benefit from wearing a Trion:Z bracelet that generates both a magnetic field and negative ions. Although many people like to rubbish the use of these innovative approaches for well-being, I urge you to try it for yourself and form a genuine opinion without jumping to a knee-jerk conclusion.” – Dr Sarah Brewer ,
