Human Gait Analysis Metric for Gait Retraining

Figure 2

As the wearer takes a step, the device pushes the foot backward during stance. This exaggeration of the asymmetry results in a more symmetric gait pattern once the shoe is removed. In addition, the shoe works to strengthen the paretic leg by slightly destabilizing the nonparetic leg, which encourages the wearer to use their paretic leg more. A flexible height- and weight-matched platform worn on the opposite foot equalizes the added height and weight of the device.
