Simplified standing function and sensory evaluation system for fall prevention

This paper proposes a simplified standing function and sensory evaluation system based on virtual light touch contact. This involves on/off control to implement random changes from a virtual partition. Such a set-up allows medical staff to quantitatively judge standing function from somatosensory stimulation changes. Experiments were implemented to determine posture controllability among subjects based on external stimulation in consideration of contact with the virtual partition, with outcomes indicating the method's suitability for clarification of how standing function and age are related, and this allow evaluation of fall risk among subjects judged to be at low risk in physical testing via comparison of sensory system evaluations using wavelet analysis.
