| Research Abstract |
We developed an adjustable attachment for intelligently controllable ankle foot orthosis (i-AFO) and produced the adjustable orthotic device which incorporated MR fluid brakes and sensors. We discovered that the relationship between walking speed and the angular velocity of ankle plantar flexion and also step length were high correlations by the analysis of the normal walk. Using this relationship, we devised a method to estimate walking speed, and built a control model. By using these devices and control model, we evaluated by a normal adult. In clinical evaluations by the handicapped person, walking speed was estimated adequately and could realize the braking torque control of the ankle which accepted estimated walking speed, and his gait was improved.
