Figure 3From: Neurophysiological study to assess the severity of each site through the motor neuron fiber in entrapment neuropathy The relationship between MDL and CMAP amplitude of the APB muscle. Relationship between MDL and CMAP amplitude measured in the median nerve of 143 symptomatic hands is shown. The MDL demonstrated a strong (r = 0.58, p < 0.0001) relationship with the CMAP amplitude.Back to article page
