Relations Between 6 Minute Walking Distance and 10 Meter Walking Speed in Patients With Multiple Sclerosis and Stroke

Dalgas U, Severinsen K, Overgaard K. Relations between 6 minute walking distance and 10 meter walking speed in patients with multiple sclerosis and stroke.ObjectiveTo investigate the relationship between a short walking test and a long walking test in patients with walking disability due to multiple sclerosis (MS) or stroke.DesignCross-sectional observational study.SettingUniversity hospital and sport science department.ParticipantsPatients with MS (n=38), patients with stroke (n=48), and healthy subjects (n=46). Patients were participants in other clinical trials.InterventionsNot applicable.Main Outcome MeasureWalking speed in a 10m walk test and a 6 minute walk test was compared.ResultsDespite differences in absolute walking speed between long and short tests, strong correlations were found between both the tests in patients with MS (r=.95) and in patients with stroke (r=.94), whereas a more moderate correlation was found in healthy controls (r=.69–.70).ConclusionsOur findings show that walking speeds of a short walking test and a long walking test are strongly correlated in both patients with MS and patients with stroke, whereas correlations in healthy subjects are weaker.
