Key takeaways:
 

 Measuring accurate walking speed in in real life:

• is possible & accurate with Syde technology
• is robust: 2-week test-retest 88% agreement
• correlates with gold standard: p-value: 10^-9

Walking speed in real life measures progression of  MS with unique precision :

• measures progression with higher statistical significance (9.10^-4 ) than EDSS (6.10^-2) for progressive patients

• measures smoldering for relapsing MS 

• measures evolution due to relapses
