RSI

Referred to various kinds of injuries to muscles, tendons or nerves. These injuries are caused by repetitive movement of a particular part of the body. RSI can also be referred to as upper limb disorder (ULD). This is because the condition often involves the upper part of the body - the forearm, elbow, wrist, hands and neck.

The most common RSI conditions include:

Bursitis: inflammation and swelling of the fluid-filled sac near a joint at the knee, elbow or shoulder.
Carpal tunnel syndrome: pressure on the median nerve passing through the wrist.
Dupuytren's contracture: a thickening of deep tissue which passes from the palm of the hand into the fingers.
Epicondylitis: inflammation of an area where bone and tendon join, e.g. tennis elbow.
Ganglion: a cyst in a tendon sheath, usually occurring on the wrist.
Rotator cuff syndrome: inflammation of muscles and tendons in the shoulder.
Tendonitis: inflammation of a tendon.
Tenosynovitis: inflammation of the inner lining of the tendon sheath that houses the tendons that control the fingers and thumbs.
Trigger finger: inflammation of the tendon sheaths of fingers or thumb accompanied by swelling of the tendon.
Diffuse RSI: nerve damage.

RSI is often caused or aggravated by frequently repeated movements such as a task or leisure activity, e.g. playing golf or tennis regularly. Symptoms usually persist over time if left untreated.
