Transient carpal tunnel syndrome accompanying rubella infection.

Four children are presented with otherwise uncomplicated rubella infection suffering from transient carpal tunnel syndrome. The diagnosis was confirmed by repeated measurements of sensory conduction velocity and sensory action potential amplitude. The symptoms were only nocturnal. They disappeared rapidly but the neurophysiological changes normalized slowly. The possibility of a carpal tunnel syndrome should be considered in a child with rubella complaining of numbing or tingling fingers during the night.
