YouTube case series of sporting injuries yields new clinical sign.

A case series of YouTube sporting injuries has identified what could be a useful clinical sign for sports coaches. The ‘fencing response’ (tonic posturing) is an immediate sign and is associated with moderate head injury. It seems to be a separate entity from convulsions, which may also occur, and since it is a clinical sign that is quite easily recognised, it can help direct care after the injury.
