This technique is often technically challenging and clinicians have difficulty interpreting the information particularly in the short segment needed to assess focal tibial nerve entrapment at the medial ankle as occurs in posterior tarsal tunnel syndrome. The flexor hallucis brevis FHB has been described as an alternative site for recording tibial nerve function in those with posterior tarsal tunnel syndrome. Normative data has not been established for this technique. This pilot study describes the technique in detail. In addition we provide reference values for medial and lateral plantar orthodromic sensory measures and assessed intrarater reliability for all measures. Methods Eighty healthy female participants took part and 39 returned for serial testing at 4 time points. Mean values SD were recorded for nerve conduction measures and coefficient of variation as well as intraclass correlation coefficients ICC were calculated. Results Motor latency amplitude and velocity values for the FHB were msec mV and m s respectively. Sensory latencies amplitudes and velocities respectively were msec pV and m s for the medial plantar nerve and msec pV and msec for the lateral plantar nerve. All values demonstrated significant ICC values P . Conclusion Motor recording from the FHB provides technically clear waveforms that allow for an improved ability to assess tibial nerve function in
