Speed-dependent temporospatial gait variability and long-range correlations in cerebellar ataxia

Highlights ► We examine magnitude and structure of gait variability in cerebellar ataxia patients. ► Pathological alterations in gait variability are dependent on the walking speed. ► Increased levels of gait variability mostly occur at slow and fast walking speeds. ► Preferred walking speed is asso...

Description
Summary:Highlights ► We examine magnitude and structure of gait variability in cerebellar ataxia patients. ► Pathological alterations in gait variability are dependent on the walking speed. ► Increased levels of gait variability mostly occur at slow and fast walking speeds. ► Preferred walking speed is associated with minimal levels of gait variability.
