This article helps to determine the incidence of distal ulnar nerve compression in cyclists, or tingling and loss of sensation in the lower-arms and hands.
Twenty-five road or mountain bike riders responded to a questionnaire and were then physically examined and interviewed before and after a 600-km bicycle ride. A total of 24% of the hands (eight cyclists) tested experienced a combination of motor and sensory symptoms.
