The most common overuse injuries are wrist and elbow pain such as carpal tunnel syndrome and tennis or golfers elbow (lateral epicondylitis and medial epicondylitis). This is often related to long periods sitting at a computer and using the mouse and keyboard. Tension in the neck and shoulders may also contribute to arm symptoms. There are a number of adaptive devices that can be useful if you have an overuse injury, such as an upright mouse, wrist rests, tennis elbow supports, ergonomic keyboards, and adjustable height desks. Some of these are more useful than others, and an assessment with a physiotherapist can help to decide which are worth purchasing for your condition. Manual therapy and dry needling / acupuncture are very useful in treating overuse injuries in conjunction with rest breaks and strengthening esercises. If you have epicondylitis, extracorporeal shock wave therapy is very liekly to help your pain. There is very little evidence that poor posture causes these issues, but it is thought that if you have poor postural habits and you have developed pain, altering your posture may help to unload the already overworked tissues and help you recover.
