The Perception of Vertical Visual Perturbation While Walking    Abstract:      By using the information our eyes collect from our surroundings, we can better stabilize  ourselves and keep in control of both standing and walking. Many studies have been done to  test the effects of horizontal and lateral visual motion, but no studies have been done of  vertical visual movement. In this study, we observed the effect that random vertical movement  of a subject’s surroundings has on the subject while walking on a treadmill, expecting that  perhaps a small but measurable response would be produced. The subjects were presented  with two different amplitude signals, while walking at 5 kilometers per hour, and their body  kinematics were measured. Frequency response functions were calculated, and the gains and  phases demonstrate interesting results – there is evidence of down‐weighting, the “ignoring” of  high amplitude perturbations that has been documented in other studies, and there are  noteworthy patterns in the gains across the frequencies studied. While reactions were stronger  in the lower frequencies in the Anterior‐Posterior direction, they were stronger in the higher  frequencies in the Medial‐Lateral direction. This is hypothesized to be because higher frequency  perturbations are also shorter period perturbations, and so they affect the subject in the span  of a single gait cycle. Phase plots show us other interesting patterns, for example an upward  movement of the vertical field leads to a forward movement of the body, which would indicate  how the body perceives these perturbations. These results together provide a compelling  argument that vertical visual feedback is in fact highly important in the maintenance of stability  of the body. The findings can be used in future studies that compare the responses of healthy  subjects to the responses of pathological walkers, which could lead to the discovery of the  causes of several types of walking disorders and corresponding treatments to help the suffering  individuals recover.


Nonequilibrium Statistical Operator-IJMPB05 94%

Perturbation of one subsystem may produce a nonequilibrium state which is then relaxed to an equilibrium state due to the interaction between particles or with a thermal bath.
