抄録

Robotics technology nowadays provides tools that can help us overcome several incapacities, as instance, power assisting devices for hemiplegics. In this paper we analyze the difference on the walking of a semi-paralyzed left leg hemiplegic patient with and without assistance provided by a walking assistive device developed at our laboratory. In order to analyze the effects of the assistance, we use electromyography sensors placed on both legs to measure the muscle activation, along with pressure sensors on the feet soles and bending sensors place on the hips and knees joints. Our results show an increase on the walking frequency, as well as, an increment on the muscle activity on the semi-paralyzed leg, against a decrease of muscular activity of the healthy leg. Pressure and bending sensors also show an increase in the legs movement. This results show the beneficial effects of using the assistive device.
