Research output: Contribution to journalArticle


The authors investigated the H-reflex at rest and during voluntary contraction on stimulation with different frequencies 0.1-20 cps). The investigations were carried out on normal individuals. In the frequency band 1-10 cps there were a 'resonancy' like increase of the reflex responses with a peak in 5-7 cps frequency band. These results were compared with previous observations of patients with chronic implanted electrodes, with the frequency resonance investigations of patients with spinal cord lesions and with normal alternating movements. According to this study the frequency resonance investigation is a useful technique for the study of central motor lesions.
