The effects of swing assistance in a microprocessor-controlled transfemoral prosthesis on walking at varying speeds and grades

Wearable Technologies, 2023
This article proposes, describes, and tests a swing-assist walking controller for a stance-controlled, swing-assisted knee prosthesis that aims to combine benefits of passive swing mechanics (e.g., quiet operation, biomimetic function, and low power ...

Interactions Between Transfemoral Amputees and a Powered Knee Prosthesis During Load Carriage

Scientific Reports, 2017
Machines and humans become mechanically coupled when lower limb amputees walk with powered prostheses, but these two control systems differ in adaptability. We know little about how they interact when faced with real-world physical demands (e.g. carrying

Comparison of the Imaging and Clinical Outcomes among the Measured Resection, Gap Balancing, and Hybrid Techniques in Primary Total Knee Arthroplasty

Orthopaedic Surgery, Volume 15, Issue 1, Page 93-102, January 2023., 2023
Hybrid technique had yielded improvements in restoring the mechanical alignment of lower limbs and realizing the optimal position of femoral and tibial components, which was not statistically different from MR and GB techniques, but superior to GP technique in maintaining the original height of joint line, which was similar to MR technique.

Invariant Neuromorphic Representations of Tactile Stimuli Improve Robustness of a Real‐Time Texture Classification System

Advanced Intelligent Systems, EarlyView.
This work presents a method to create neuron‐like (neuromorphic) spiking representations of texture that are invariant to the scanning speed and contact force applied in the tactile sensing process. In offline and real‐time experiments, these representations improve classification accuracy, computational efficiency, and the ability to identify textures

Asymmetry of Posterior Condyles in Resection Plane and Axial Curvature for Total Knee Arthroplasty

Orthopaedic Surgery, Volume 14, Issue 12, Page 3340-3348, December 2022., 2022
Asymmetry of the Posterior Condyles for TKA A prosthetic overhang at the lateral posterior condyle's posterolateral aspect could arise while using the TKA prosthesis with posterior condyles of symmetrical shape because of the asymmetry in resection bone plane.

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

arXiv, 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.
