Mean (SD) for each group for the measures taken from ten walks (two each at self-selected very slow, slow, preferred, fast and very fast speeds). Note the stride length – cadence relationship (SLCrel) measures excluded walks with cadence >150steps/min and two outlying PD participants’ data was excluded

SLCrel stride length versus cadence relationship, nSL normalized stride length, cad=cadence, PSP progressive supranuclear palsy, PD Parkinson’s disease, HOA healthy older adult.
