Abstract
The purpose of this study is to investigate the effects of sex and age and their interactions in premotor-time (PMT) of ankle muscle. Forty-eight elderly subjects (aged 65-90 years) and thirty young subjects (aged 19-27 years) participated in this study. Subject were instructed to perform maximal, voluntary, isometric, bilateral contraction of ankle muscle in reaction to auditory stimulus to determine PMT. As analysis variables, PMT, intrasubject variability of PMT and asymmetry of PMT between dominant and nondominant legs were used. As statistical analysis, two-way ANOVA was performed to assess the main effects of age group and sex and also their interactions. All variables showed significant age effects (p<0.01). However, no sex effect and interaction existed in all variables in both dominant and nondomiant legs. Theses results suggest that the PMT of ankle muscle is related to the age-related deterioration in postural control, however, not related to the sex-difference of fall incidence in the elderly population.
