	Abstract

We used a global positioning satellite technology odometer to determine the maximum objective walking distance capacity (MOWD) of patients with multiple sclerosis (MS). The MOWD correlated with Expanded Disability Status Scale (EDSS) score (r ²=0.41; P<0.0001), the MSWS-12 scale (r ²=0.46; P<0.0001), time to walk 10 m (r ²=0.51; P<0.02) and walking speed (r ²=0.75; P<0.001). Limitation of walking capacities was measurable up to 4550 m, strikingly above the 500-m limit of the EDSS. This objective odometer is a promising tool for evaluation and follow-up of patients with MS.
