[Comparison of the blink-reflex obtained using needle electrodes and surface electrodes (author's transl)]

The electrically released Blink-Reflex was registered on four channels simultaneously using needle- and surface-electrodes. 17 healthy volunteers were examined. The latencies of the R1-, R2- and R2'-components are comparable using both recording technics. The amplitudes of the reflex components however show great variation using as well needle- and surface electrodes. The amplitudes didn't turn out to be more stable using surface electrodes. For the clinical use this result implies that both recording technics produce comparable latencies and therefore can be used alternatively according to the special necessities of examination.
