Ulnar nerve at the elbow – normative nerve conduction study

Table 4 Shows descriptive statistics for the parameters of motor and sensory conduction of the NM, recorded from APB for motor conduction and from digit II for sensory conduction

Median nerve conduction parameters	Mean [SD]	Reference range (95% tolerance interval)
DML wrist 8 cm [ms]	3.54 [0.34]	2.82-4.26
MNCV forearm [m/s]	57.1 [4.6]	47.6-66.7
A-CMAP wrist [mV]	10.0 [3.0]	3.7-16.6
A-CMAP elbow [mV]	9.7 [3.0]	3.4-16.0
SNCV [m/s]	55.8 [4.7]	45.9-65.6
Amp-SNAP [μV]	25,7 [4, 11]	8.0.-51.7

In the last column, reference ranges defined with 2.5^th and 97.5^th percentile are given for each parameter.
