Description of walking in the Ekso: The users are progressed through a series of steps to participate in over ground ambulation. The first method, called FirstStep. This is when the trainer triggers the step by using a controller while verbally cueing the participant that the device is taking a step. The second method, called ActiveStep is when the user to initiates the stepping action by pressing a button on a pair of instrumented crutches for each step. The last method, called ProStep, is when the user shifts their weight lateral and forward onto the front foot, until sensors indicate when an appropriate shift has been performed. The stepping pattern can be adjusted to change the step time and step length. The trajectory of the foot allows for foot clearance similar to a marching pattern. The device has the ability for provide some abduction and plantar/dorsi flexion positioning. This device has the ability to alter the stepping, which would allow the user to take faster or slower steps with a longer or shorter stride length, thus permitting a walking velocity of 0.10 to 0.45 m/s. Stopping is achieved by holding a stationary position and by not activating sensors. The Ekso allows for varying robot-assist levels that can be decrease or increased bilaterally. The robot assistance can operate will full or variable assist, dependent on the level of function of the individual.
