Usual gait speed (meters/second) by age and gender among individuals with sickle cell disease The figure displays the fastest of 2 usual gait speed trials stratified by age decade. The mean gait speed for all participants was 1.12 m/s (95% CI 1.06, 1.18). The majority of participants (63%) had a gait speed slower than 1.2 m/s (the speed necessary to safely cross the street at an intersection). Twenty-five percent had a gait speed slower than 1 m/s
