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. Web1 de mai. de 2002 · The clearly identified F -waves were recorded and automatically analyzed by the program for: the minimal F -wave latency ( F min), maximal F -wave latency (the longest) ( F max), and the maximal-minimal latency difference (FΔ) to assess the degree of scatter among the repeated F -waves ( F -chronodispersion).
