The Findings

Figure A shows the fraction of stimuli that were detected while standing, walking and jogging by 8 normal subjects with a vibrotactile stimulator placed on their arm. A_fraction.JPG
Figure B shows that the subjects’ response time is also longer when they are active, particularly at lower stimulus amplitudes A_time.JPG
Figure C shows that the fraction of stimuli detected was lowest in late swing and early stance, which are both near the event of heel strike where disturbance accelerations are largest B_fraction.JPG
Figure D shows that the response time is longest when the stimulus is presented in early stance, just after heel strike
