Frequency Domain Characteristics Of Ground Reaction Forces During Walking Of Young And Elderly Females, Nicholas Stergiou, Giannis Giakas, Jennifer E. Byrne, Valerie Pomeroy

Objective. To examine the frequency domain characteristics of the ground reaction forces of young and elderly females during free walking.

Design. Independent t-tests were used to examine the frequency content of all three components of the ground reaction force.

Background. Frequency domain analysis has the potential to assist in identifying changes in gait that may be masked in the time domain. No research has been done to identify changes in gait due to age-related impairments in the frequency domain.

Methods. Ten young and ten elderly females walked at a prescribed speed while ground reaction forces were collected via a ...

This study investigated intralimb coordination during walking in Young and Elderly women using the theoretical model of dynamical systems. Twenty females, ten Young (M age = 24.6 yrs, SD = 3.2 yrs), and ten Elderly (M age = 73.7 yrs, SD = 4.9 yrs), were videotaped during free speed gait and gait perturbed by an ankle weight. Two parameters, one describing the phasing relationship between segments (mean absolute relative phase) and the other the variability of this relationship (deviation in phase), were calculated from the kinematics. Two-way ANOVA (age and weight) with repeated measures on weight indicated that during the ...
