Tibial nerve F-waves recorded from the abductor hallucis.
The purpose of this study was to develop a large database of normal values for the tibial nerve F-wave. A total of 159 asymptomatic subjects without risk factors for neuropathy were recruited and had ten tibial F-waves performed on each leg. Data were collected for the shortest F-wave (Fmin), the mean F-wave (Fmean), and the range of F-waves (Frange). Age, gender, and height were associated with differences in the results. The mean Fmin was 50.8 +/- 5.3 ms. Mean Fmean was 53.0 +/- 5.6 ms and mean Frange was 4.5 +/- 2.4 ms. The mean side-to-side difference for Fmin was 0.6 +/- 2.3 ms and the mean side-to-side difference for Fmean was 0.4 +/- 2.5 ms.
