From: Gait patterns during overground and virtual omnidirectional treadmill walking
Average step length for each forward walk trial is plotted versus average gait speed for the trial, with the corresponding linear mixed model (LMM) overlaid for each condition. The LMM includes fixed effects of condition and velocity, as well as random intercepts and slopes by condition for participant ID. Each point represents the average step length for a single forward walk trial. The distribution of the step length data, as well as the LMM fit, are representative of all spatiotemporal outcomes and models
