Figure 4From: How useful is satellite positioning system (GPS) to track gait parameters? A reviewTimes series of gait parameters for a walking man (preferred speed). The gait parameters were measured in a male volunteer stride by stride (1 stride = 2 steps) over ~32 min. by using the high accuracy GPS method. The intra-individual (stride to stride) variability is expressed as both Standard Deviation (SD) and Coefficient of Variation (CV = SD/mean × 100). Total distance, number of strides and duration are indicated below.Back to article page
