Mainly walking speed correlations (Pearson).

Variable	Walking speed
Disability (EDSS)	−0.740
Balance confidence (ABC scale)	0.703
Walking impact (MSWS-12)	−0.677
Motor imagery (mental chronometry)	0.556
Recurrent falls	0.445
Fatigue (MFIS)	−0.423
Physical activity (IPAQ)	0.315

All correlations are statistically significant (P < .01). EDSS: Expanded Disability Status Scale. ABC scale: Activities-Specific Balance Confidence Scale. MSWS-12: Multiple Sclerosis Walking Scale-12. MFIS: Modified Fatigue Impact Scale. IPAQ: International Physical Activity Questionnaire.
