Online Reinforcement Learning Control for the Personalization of a Robotic Knee Prosthesis
Robotic prostheses deliver greater function than passive prostheses, but we face the challenge of tuning a large number of control parameters in order to personalize the device for individual amputee users.

Formation of buckling resistance in a transfemoral prosthesis
Introduction. The principles of construction of the knee joint in the transfemoral prosthesis are considered. The design of the knee joint in the transfemoral prosthesis with an original mechanism for ensuring buckling resistance in the prosthesis is ...

The use of the constrained prosthesis in the difficult primary knee arthroplasty [PDF]
Background: The constrained knee prosthesis has the basic indication in revision arthroplasty, but the latest literature reveals that it takes place also in primary total knee arthroplasty in cases of knee osteoarthritis associated with major ...

An investigation into a locking mechanism designed for a gear-based knee joint prosthesis
Background: The knee-locking mechanism in an above-knee prosthesis is crucially important to protect the prosthesis user from sudden falling down due to unexpected disturbance while standing upright.

Robotic Knee Tracking Control to Mimic the Intact Human Knee Profile Based on Actor-critic Reinforcement Learning [PDF]
We address a state-of-the-art reinforcement learning (RL) control approach to automatically configure robotic prosthesis impedance parameters to enable end-to-end, continuous locomotion intended for transfemoral amputee subjects. Specifically, our actor-critic based RL provides tracking control of a robotic knee prosthesis to mimic the intact knee ...

Virtual Testing Method of Human Knee Prosthesis
In the human knee joint, a degenerative wear of the joint can be formed, the common treatment of this disease is the total knee prosthesis geometry replacement and prosthesis implanting, the aim of our research is the study of the human knee joint with ...

Modeling and Control of Knee-Ankle-Toe Active Transfemoral Prosthesis
The main joints of lower limb are hip, knee, ankle, and toe. Because of accidents or diseases, some people have to amputate. Wearing prosthesis can help them return to normal life.
