H-reflex recorded by multi-pad EMG electrodes

Abstract

We recorded H-reflex using 4 × 4 multi-pad EMG electrodes on muscle Soleus from 4 healthy subjects. The results indicate that the new proposed method of recording H-reflex provides more information than standard bipolar or unipolar EMG recording, since it enables spatial and temporal parameters assessment. We have developed an algorithm which can automatically select the H-reflex with maximum peak to peak amplitude. We also examined the H-reflex propagation by the use of EMG topography map based on the latency.
