Table 3: Change in Spatiotemporal parameters. Changes in spatiotemporal parameters pre and post intervention in responders versus non-responders are represented here. Note how all parameters change appropriately in responders (increased velocity, increased stride and step length with reduction in percent time of double support), and move in the opposite direction in non-responders except for a slight increase in velocity.
