SUMMARY

A study has been made of the isometric twitches of hypothenar and calf muscles in man. The twitch contraction time for hypothenar muscles ranged between 55 and 78 ms, while for the calf muscles it ranged between 90 and 125 ms. According to their speed of contractions the hypothenar muscles were considered belonging to the so called intermedious group while the calf muscles integrate the slow group. It has been also demonstrated that these techniques can successfully be applied to the investigation of several neuromuscular disorders.


RESUMEN

Se realizo un estúdio de la contracción isométrica de los músculos de Ia eminencia hipotenar y pantorrilla en el hombre. Los tiempos de contracción para los músculos de la eminencia hipotenar variaron entre 55 y 78 ms, en tanto que los correspondientes a la pantorrilla lo hicieron entre los 90 y 125 ms. En base a estos tiempos los primeros fueron classificados dentro del grupo de músculos intermedios, en tanto que los últimos lo fueron en el lento. Se resalta la importancia de estas técnicas en el estúdio de Ia patologia neurológica periférica.
