The pain of RSI. The central issue.

In this paper RSI (repetition strain injury) is used to refer to those diffuse neck and arm pain syndromes that appear to be directly related to occupational factors; for example, occupational overuse syndrome (OOS) and occupational cervicobrachial disorder (OCD). The author examines the clinical evidence that suggests the involvement of neural tissues in the pathogenesis of these conditions. He also speculates on the possible underlying pathophysiological mechanisms that may explain their development and persistence.
