Entraining human gait with periodic torque from a robot may provide a novel approach to robot-aided walking therapy that is competent to exploit the natural oscillating dynamics of human walking. To test the feasibility of this strategy we applied a periodic ankle torque to neurologically impaired patients (one with stroke and one with multiple sclerosis). As observed in normal human walking, both...
Functional electrical stimulation (FES) is used to assist spinal cord injury patients during walking. However, FES has yet to be shown to have lasting effects on the underlying neurophysiology which lead to long-term rehabilitation. A new approach to FES has been developed by which stimulation is timed to robotically controlled movements in an attempt to promote long-term rehabilitation of walking...
The main objective of this work was to evaluate and compare the effects of Functional Electrical Stimulation (FES) therapy in the walking ability and muscle strength studied by electromyography (EMG) analysis between subacute and chronic stroke patients. Eighteen consecutive hemiplegic patients suffering from foot drop were assigned either to subacute or chronic group. Patients of both groups' were...
