Optimization reduces knee-joint forces during walking and squatting: Validating the inverse dynamics approach for full body movements on instrumented knee prostheses [PDF]

open access: yesarXiv, 2021
Due to the redundancy of our motor system, movements can be performed in many ways. While multiple motor control strategies can all lead to the desired behavior, they result in different joint and muscle forces. This creates opportunities to explore this redundancy, e.g., for pain avoidance or reducing the risk of further injury.

Joint Action is a Framework for Understanding Partnerships Between Humans and Upper Limb Prostheses [PDF]

open access: yesarXiv, 2022
Recent advances in upper limb prostheses have led to significant improvements in the number of movements provided by the robotic limb. However, the method for controlling multiple degrees of freedom via user-generated signals remains challenging. To address this issue, various machine learning controllers have been developed to better predict movement ...

Intelligent ankle–foot prosthesis based on human structure and motion bionics

open access: yesJournal of NeuroEngineering and Rehabilitation
The ankle–foot prosthesis aims to compensate for the missing motor functions by fitting the motion characteristics of the human ankle, which contributes to enabling the lower-limb amputees to take care of themselves and improve mobility in daily life. To

Retractable Prosthesis for Transfemoral Amputees Using Series Elastic Actuators and Force Control [PDF]

open access: yesarXiv, 2015
We present a highly functional and cost-effective prosthesis for transfemoral amputees that uses series elastic actuators. These actuators allow for accurate force control, low impedance and large dynamic range. The design involves one active joint at the knee and a passive joint at the ankle.
