A Scatter plots with regression lines showing the relationship between average daily walking distance and 10 Meter Walk Test (10MWT) speed at baseline, midterm and final visits. B Scatter plots with regression lines illustrating the relationship between the baseline Functional Independence Measure (FIM) total score and average daily walking distance, stratified by walking speed category (slow: <0.6 m/s, fast: ≥0.6 m/s). C Scatter plots with regression lines illustrating the relationship between the baseline Functional Independence Measure (FIM) motor subscore and average daily walking distance, stratified by walking speed category (slow: <0.6 m/s, fast: ≥0.6 m/s)
