Evaluation of the interaction between human and power assist orthosis

We have developed a powered assistive orthosis, for paraplegic persons. The orthosis has four actuators on the thighs and the knees. The actuators are controlled by the corresponding Central Pattern Generators. It could change the walking orbit on variation of wearer and environment, so that this orthosis could assist wearer smoothly. In order to design more effective orthosis, we consider here to introduce another degree-of-freedom of controlled actuator to this powered orthosis. We consider here to introduce evaluation of the interaction between human and power assist orthosis.
