WebMotor NCSs demonstrate normal amplitudes, distal latencies, and conduction velocities in myasthenia gravis. In LEMS, the amplitudes of the compound muscle action potentials (CMAPs) usually are low. After the muscle is exercised for 10 to 15 seconds, the CMAP amplitude typically is 200% higher than the baseline value in patients with LEMS. Web26 de mai. de 2016 · For both latencies and conduction velocities, gender and age were found to have small but significant effects, and these subgroups are shown in Table 4.
