(A) Coefficient of variation of inter-step-intervals when waking to a metronomes or music at all experimental tempi in persons with multiple sclerosis (PwMS), divided by patients walking with assistive devices (n = 8) and patients walking without assistive devices (n = 20). Mean and standard errors of mean are shown. (B) Co-efficient of variation of inter-step-intervals plotted against baseline speed (m/s) at all experimental tempi in all participants (healthy controls and PwMS) when walking to both music and metronomes.
