Longitudinal change in spatiotemporal gait symmetry after discharge from inpatient stroke rehabilitation

Purpose: To describe the change in spatiotemporal gait asymmetry after discharge from stroke rehabilitation and examine the relationship with change in other clinical outcome measures.Methods: Secondary analysis of a prospective cohort study was conducted. Swing time and step length symmetry, balance, mobility, gait speed, and motor impairment were assessed at discharge and 6 months later. Participants (n = 61) were classified by shift in symmetry status (Asymmetric-to-Symmetric, Symmetric-to-Asymmetric, No Shift) and magnitude of difference scores (Improved, Worse, No Difference). Correlations between change in spatiotemporal symmetry and the other clinical measures of physical status were calculated.Results: At discharge, 61% (37/61) and 36% (22/61) of participants were asymmetric in swing time and step length, respectively. Of this subgroup, 43% (16/37) and 50% (11/22) shifted to symmetric gait by follow-up. In contrast, only six individuals significantly improved in swing and/or step symmetry ...
