[Electrically induced cutaneo-muscular reflex from the m. extensor digitorum brevis].
We recorded the cutaneo-muscular reflexes in 90 normal subjects from the extensor digitorum brevis muscle following electrical stimulation at the second toe. In 88 subjects an early and a late EMG response were obtained. The mean latency of the second reflex response was 91.9 +/- 12.1 ms and the mean duration was 27.3 +/- 11.6 ms. However, there was considerable variability of the interindividual amplitudes. Comparison of the age related changes in the latencies of the first and second reflexes yielded results consistent with the transcortical or spino-bulbo-spinal hypothesis.
