Control of Body Sway Using Tactile Stimuli on the Body Trunk

In this research, we examined a technique in which the production of body sway in a desired direction was considered using a v ibro-tactile stimulator. It is necessary to create body sway in a specific direction t o assist in postural control. Therefore, this study aimed to introduce a device that creates spatio-temporal tactile stimulation patterns by altering the interval times between vibrations. We measured body sway caused by each stimulation using a high-speed camera, stabilometer, and acceleration sensor. We then analyzed the effects of each stimulation on body sway. As a result, this study suggests the optimal time duration and interval of stimulations for a specific direction.
