Electrophysiologic analysis of motor nerves and sensory nerves in Swl/+ and wild-type mice

Parameters	Units	WT (n = 12)	Swl/+ (n = 13)
MDL	ms	1.4 ± 0.09	1.4 ± 0.08
MPL	ms	1.9 ± 0.10	1.9 ± 0.09
MCV	m/s	30.1 ± 1.32	27.7 ± 1.25
MAmp (D)	mV	27.0 ± 3.95	28.2 ± 3.54
MAmp (P)	mV	24.8 ± 3.75	26.5 ± 3.64
SL	ms	0.5 ± 0.02	0.6 ± 0.03
SAmp	μV	21.3 ± 1.13	14.5 ± 1.30*
SCV	m/s	22.9 ± 0.85	20.9 ± 0.97

In sciatic nerves, distal latencies (MDL), proximal latencies (MPL), motor nerve conduction velocities (MCV), and distal (D) and proximal (P) compound muscle action potential amplitudes (MAmp) are measured. In sural nerves latencies (SL), sensory nerve action potential amplitudes (SAmp) and sensory nerve conduction velocity (SCV) are measured. Tests are performed in 13-week-old Swl/+ mice and age-matched WT mice. No significant difference is detected between two groups, except that the sensory potential amplitude is reduced by 32% in Swl/+ mice.
