Expressing the severity of carpal tunnel syndrome in reports of nerve conduction studies is a source of longstanding argument amongst neurophysiologists and enormous variation in actuak practice. This situation is confusing to our surgical colleagues and contributes to their widespread belief that nerve conduction studies are meaningless in CTS. I wish to propose that we adopt a uniform way of expressing neurophysiological severity across the UK and will briefly describe my own scheme and why I think it works, leaving adequate time for discussion.
