1.4 THE TWO-DIMENSIONAL SYSTEM: OPTOGAIT 2D
Starting from version 1.7 of the OptoGait software it is possible to use a particular bar configuration
for obtaining a two-dimensional measurement area. To the classic bars (which we will call X) more
bars (Y) can be added to form a rectangle, where new information can be gathered for the gait tests:
Step width: distance between the middle support point of each foot
Walking Base: distance between the innermost foot support points (for superposed steps
this value can be negative)
Walking Points: middle points between the two support feet; their connection defines the
gait progress (Line of Progression); conventionally it is expressed in positive values if there
is a deviation towards left and negative with a rightward deviation
Walking Point Gap: progressive variation of the current walking point with respect to the
previous one
