Towards Expedited Impedance Tuning of a Robotic Prosthesis for Personalized Gait Assistance by Reinforcement Learning Control [PDF]
IEEE Transactions on Robotics, 2021, 2020 Personalizing medical devices such as lower limb wearable robots is challenging. While the initial feasibility of automating the process of knee prosthesis control parameter tuning has been demonstrated in a principled way, the next critical issue is to improve tuning efficiency and speed it up for the human user, in clinic settings, while maintaining ...

Formosan Journal of Musculoskeletal Disorders, 2023 Periprosthetic fractures (PPFs) in total knee arthroplasty (TKA) are challenging for orthopedic surgeons. A floating knee injury around TKA, especially with component loosening, attributes more complexities in management for the joint reconstruction ...

Early detection of hip periprosthetic joint infections through CNN on Computed Tomography images [PDF]
, 2023 Early detection of an infection prior to prosthesis removal (e.g., hips, knees or other areas) would provide significant benefits to patients. Currently, the detection task is carried out only retrospectively with a limited number of methods relying on biometric or other medical data.

Cosmetic effect of knee joint in a knee disarticulation prosthesis [PDF]
Journal of Rehabilitation Research and Development, 2014 Despite numerous advantages, knee disarticulations (KDs) are rarely performed because of the anticipated KD prosthesis fitting problems that include the positioning of the knee joint distally from the KD socket. This results in lengthening of the thigh and subsequent shortening of the shank. The objective of this study was to assess the cosmetic effect
