Transient Paresthesia in Stair-Climbers' Feet.

In brief The authors surveyed frequent users stair-climbing machines at seven health clubs to determine if neurologic foot symptoms were present. Of 212 respondents, 39% reported that they experienced numbness or tingling in their feet while using stair-climbing machines. The mild-to-moderate forefoot symptoms generally disappeared as exercise continued or when the session ended. Compression of the interdigital nerves from persistent and prolonged weight bearing possibly causes this transient paresthesia. If patients seek medical care for these symptoms, ruling out other foot neuropathies is important. Patients may be able to alleviate symptoms by slightly altering their workout technique.
