Motor Evoked Potentials after Supraspinal Stimulation in Pre- and Postoperative Evaluations of Patients with Cervical Radiculopathy

Figure 3

MUAP recordings from the basic EMG on the abductor pollicis brevis muscle in (a) a healthy volunteer from the control group, and in (b) a patient with cervical radiculopathy. Part (a) of the figure shows the MUAP with correct parameters for amplitude, duration, and area, and part (b) of the figure shows the MUAP with increased values of the parameters for amplitude, duration and area.
