Evaluation of peripheral sensory nerve function
±
The conduction velocity of the median nerve SNAPs was significantly slower in patients with MD than in controls on either side (left side: control: 53.7 ± 4.9 m/s; MD: 50.9 ± 5.0 m/s; p = 0.0001; right side: control: 53.6 ± 5.1 m/s; MD: 50.8 ± 5.1 m/s; p = 0.0002), despite adjustments for multiple comparisons via Bonferroni correction. There were no significant differences in the amplitude of the median nerve compound SNAPs between the controls and patients with MD on either side (left side: control: 21.5 ± 13.8 µV; MD: 23.5 ± 18.1 µV; p = 0.7886; right side: control: 17.8 ± 12.4 µV; MD: 18.4 ± 13.6 µV; p = 0.9517).
