Instrumented Dynamic Platform for Observing Human Postural Sway: A Preliminary Study

Abstract

This paper presents a novel design of a dynamic instrumented platform for observing the human postural sway. The body sway parameters were recorded using a force platform that was constructed with FSRs, and was fitted snugly on the surface of the dynamic platform. There are two conditions being studied in this paper, subjects are required to try and achieve a 'standing quiet' stance, with their feet in a comfortable position, with their eyes open (EO) and followed by an eye close (EC). The position of the center of pressure was then recorded as a function of time. The discussion and experimental findings of the recorded data will be discussed further in the paper. The sample size of the subjects was set to be 8, with the age of the subject specifically set to be between 25 and 27 -with the average age of 25, to avoid any influence that age might have on affecting the subject's postural sway.
