  • Abstract In recent centuries, the average life expectancy has significantly increased. Our society is thus becoming an aging society. Therefore, the nursing problem for elder people has received a lot of attention. When people get older, their muscle strength, focus ability, and physical strength inevitable decline. As a result, the risk of falling increases significantly with aging. Since falling is an independent risk factor of death for elder people, preventing falling by evaluating the balance ability has becoming an important issue.
    To toward this goal, dynamic posturography evaluates postural stability by disrupting a stable stance and measuring the postural response to such external perturbations. In contrast, static posturography measures the postural steadiness of the human body without any external excitation.
    To goal of this work is to investigate the possible correlations between the static and dynamic posturography features. Extracted from the EMG signals measured from 12 different locations, the dynamic posturography features employed in this study include IEMG and latency-time. Based on the measurements of a force platform, the employed static posturography features include conventional COP features and features developed in this work.
    By disrupting the stable stance of 11 tests subject from both forward and backward directions, the experimental results find outs that correlations between the static and dynamic posturography features are direction and muscle dependent.
    A possible application of these results is try to predict the performances of dynamic posturography by using the results obtained from static posturography since the latter is much simpler to perform than the former.
