Sampling rate influences the regularity analysis of temporal domain measures of walking more than spatial domain measures.

ABSTRACT:

Background

The spatiotemporal dynamics of stepping can provide useful information about walking performance. Most often, the identification of gait motion is performed using 3-D cinematography. The sampling rate of motion capture systems may influence the accuracy of these measures albeit in varying degrees for measures within the spatial versus temporal domain.

Research question

What are the effects of sampling frequency on common analysis methods of measures within the spatial and temporal domain?

Methods

Specifically, mean, variability (i.e. standard deviation), and regularity (i.e. sample entropy) of step length (i.e. spatial domain) and step time (i.e. temporal domain) measures were assessed following ten minutes of preferred-speed treadmill walking in eleven you
