The present study compares the effects of different types of movement on median nerve somatosensory evoked potentials (SEPs) recorded from frontal, central and parietal electrodes. Test conditions included tactile exploratory movements, repetitive active and passive thumb movements and isometric contraction. All these conditions modified the SEPs in a similar manner. Parietal N20, P25, and N60, central P22 and N32, and frontal N25, N30 and P40 deflections were diminished, while later centro… CONTINUE READING
