動作にともなう発声の実態調査とその生理的効果の検討

抄録

The objectives of this research are to implement the examination and the analysis of the utterances that accompany movements, and to elucidate whether these utterances are likely to be applied as movement-support technology. In the first phase of the field survey, we studied changes in the rate of vocal output with changes in the height of a platform to stand on; then, in the second phase of the survey, we investigated the influence exerted by vocal output or the absence thereof on walking ease and Maximum Walking Speed (MWS). In the analytical study, we observed excitation levels of spinal motor cells in healthy adults using H-wave. It is suggested by the results that (1) the rate of vocalization changes, (2) MWS is not improved, (3) the ease of walking is affected, and (4) the level of stimulation of spinal cord motor cells is increased.
