title: [Quantitative assessment, sex traits and types of chronograms of the Achilles reflex].
abstract: The time of Achille's reflex was measured with the aid of an independent electronic device tirocron in 104 normal natives of the Zambian Republic. In males the time of the reflex was significantly shorter (299.8+/-4.6 msec for the right and 303.4+/-4.9 msec for the left foot) than in mussles (326.1+/-5.6 and 329.9+/-5.9 respectively). Difference in the time of the reflex on the right and left foot in males and females was not noted. The "warmup phenomenon" was more frequently seen in females with the same frequency on the right and left feet. Three types of chronograms of Achille's reflex were depicted: stable, relatively stable and disseminated. The stable type prevaled on the right foot as compared to the left one and in males as compared to females. The disseminated type was more frequently seen in females on the left side. In determing the time of Achille's reflex it is necessary to use the arithmetical mean not less than 15--20 measurements.
