Resumo
Quantitative analysis of normal values of motor unit action potentials duration and amplitude of muscles tireoaritenoideus (TA), cricotireoideus (CT), cricoaritenoideus lateralis (CAL), and cricoaritenoideus posterioris (CAP) was performed in 14 adult normal Brazilian volunteers. The recordings were obtained by percutaneously inserted concentric needle electrode. Different motor unit action potentials were manually selected in each muscle for quantitative computerized analysis of duration and amplitude. The mean values for duration and amplitude were respectively 3.8 ms and 413 μV for TA, 4.9 ms and 585 μV for CT, 4.1 ms and 388 μV for CAL and 4.5 ms and 475 μV in CAP. There were no similar reports of normal values of motor unit action potentials in Brazilian subjects.
