Occupational disorders: non-specific forearm pain

Work-related upper limb disorder is a non-specific diagnosis for pain in the hand, wrist or, in particular, forearm once more discrete clinical conditions such as epicondylitis, tenosynovitis and carpal tunnel syndrome have been excluded. The pathophysiology of the condition is uncertain, although it is normally held to be related to an ergonomic incident. Ergonomic factors either at work or at home remain important and are discussed. Initial management is based on modification of ergonomics with appropriate periods of rest and job rotation. Treatment, however, remains somewhat unfocused and unsatisfactory. Much can be learnt from the ergonomic study of musicians, where the condition is perhaps at its most refined. Medico-legal aspects and recent thoughts on pathogenesis are also discussed.
