Walk ratio (step length/cadence) as a summary index of neuromotor control of gait: Application to multiple sclerosis

Research output: Contribution to journalArticlepeer-review

Abstract

In healthy adults, the step length/cadence ratio [walk ratio (WR) in mm/(steps/min) and normalized for height] is known to be constant around 6.5 mm/(step/min). It is a speed-independent index of the overall neuromotor gait control, in as much as it reflects energy expenditure, balance, between-step variability, and attentional demand. The speed independence of the WR in patients with multiple sclerosis (MS), and its capacity to discriminate (a) across patients with MS and controls and (b) among disability levels in MS were tested. The WR was computed in 30 outpatients with MS [20 women, 10 men; Extended Disability Status Scale (potential range: 0-10, observed median 3.5, range 2.5-5.0)] walking at free speed (range: 0.43-1.67 ms -1), and in 30 healthy controls (20 women, 10 men) at free and slow speed (range: 0.55-1.67 ms -1). The WR was 6.38±0.66 in controls versus 5.36±0.86 in patients with MS (P
