Studies have shown locomotor adaptation of the ankle to assistive torques, but the ability of the knee to adapt to assistive forces has not yet been explored. Understanding how humans modulate knee joint kinematics during gait could be valuable for designing assistive devices for stroke patients. In this study we examined how healthy subjects adapt to knee flexion torque assistance during gait. We...
Ankle-foot orthoses (AFOs) are orthotic devices supporting movements of ankles for disabled people for example hemiplegia, peroneal nerve palsy, etc. In our research, we have developed the intelligently controllable AFO (I-AFO) which can control its ankle torque by using compact magneto-rheological fluid (MRF) brakes. In this paper, we describe the gait-control tests with I-AFO for a patient of the...
In this paper, we present the results of walking experiments with a below-knee amputee fitted with a biologically-inspired prosthesis. The design of the prosthesis is described together with the characteristics and working principle of its actuators. First experimental results with an amputee are presented that demonstrate the encouraging performance of the prosthesis in restoring ankle torque to...
