Figure 1.

Two panels showing electromyography data. The left panel displays two nerve conduction waveforms on a blue grid, one basal and one post-exercise, with diference in amplitude of the potential. The right panel is a black and white line graph of overlapping motor unit action potentials for the abductor digiti minimi muscle, the first one depicting 3Hz repetitive nerve stimulation and the second one depicting post-exercise facilitation.

Example of the second neurophysiological study. Values of NCS and RNS. Baseline and post- exercise motor nerve conduction study of the ulnar nerve recorded from the right abductor digiti minimi muscle, with a 112% increment of the compound muscle action potential after brief maximal voluntary contraction. Decremental response after 3HZ low-frequency repetitive nerve stimulation and posterior increment following brief maximal voluntary contraction.
