Time-integrated propulsive and braking impulses do not depend on walking speed.

ABSTRACT:

Background

Enhancing propulsion during walking is often a focus in physical therapy for those with impaired gait. However, there is no consensus in the literature for assessing braking and propulsion. Both are typically measured from the anterior-posterior ground reaction force (AP-GRF). While normalization of AP-GRF force by bodyweight is commonly done in the analysis, different methods for AP-GRF time axis normalization are used.

Research question

Does walking speed affect propulsion and/or braking, and how do different methods for calculating propulsion and braking impact the conclusion, in both healthy adults and those with lower limb impairment?

Methods

We investigated three different analysis methods for assessing propulsion. 1. BW-TimeIntegration: Bodyweight (B
