Electrophysiological findings	MT N (75)	NMT N (75)	P-value
Superficial peroneal nerve SNAP (amplitude µv)	3.2 ± 5.7	5.9 ± 6.9	< 0.05
Superficial peroneal nerve sensory conduction velocity (m/s)	31.1 ± 7.1	35.0 ± 8.5	< 0.05
Sural nerve SNAP (amplitude µv)	3.3 ± 6.1	6.1 ± 7.5	< 0.05
Sural nerve sensory conduction velocity (m/s)	32.9 ± 9.1	36.1 ± 7.7	< 0.05
