a + b: Left and right swing time values for all the strides of the two minute walk are shown for a healthy adult (figure 1a) and a patient (figure 1 b). Mean values of the right leg swing times were 0.47 seconds and 0.43 seconds for the control and stroke patient, respectively. The corresponding values for the left leg (paretic leg of the stroke patient) were 0.45 seconds and 0.64 seconds, respectively Healthy adult: mean number of steps/minute: 103; mean gait speed: 1.28 m/s. Stroke patient: mean number of steps/minute: 78.5; mean gait speed: 0.65 m/s. Both healthy adult and stroke patient had a number of steps/minute and gait speed in the bottom range of their groups (Table 2).
