Electrophysiological assessment
The neurological assessment SEPs were recorded from the bilateral MN and TN using a Neurowerk EMG two-channel device by the methods described by Muzyka and Estephan [The latencies of several components for the MN (N13, N20, P25) and TN (N35, P40, N50) were evaluated, together with central nerve conduction in the MN (P25–N13) and TN (N50–N35). Furthermore, the amplitudes of N20/P25 in the MN and N35/P40 in TN were measured. A detailed description of the SEP measurement process and the measured TN/MN components of the primary somatosensory complex can be found (online data 2)
