IEEE Transactions on robotics, 2020 Powered prostheses can enable individuals with above-knee amputations to ascend stairs step-over-step. To accomplish this task, available stair ascent controllers impose a predefined joint impedance behavior or follow a preprogramed position trajectory ...

Categorisation of activities of daily living of lower limb amputees during short-term use of a portable kinetic recording system: a preliminary study [PDF]
, 2011 The purpose of this preliminary study was to determine the relevance of the categorisation of the load regime data to assess the functional output and usage of the prosthesis of lower limb amputees.

Design and Control of a New Biomimetic Transfemoral Knee Prosthesis Using an Echo-Control Scheme
Journal of Healthcare Engineering, 2018 Passive knee prostheses require a significant amount of additional metabolic energy to carry out a gait cycle, therefore affecting the natural human walk performance.

Reinforcement Learning Enabled Automatic Impedance Control of a Robotic Knee Prosthesis to Mimic the Intact Knee Motion in a Co-Adapting Environment [PDF]
arXiv, 2021 Automatically configuring a robotic prosthesis to fit its user's needs and physical conditions is a great technical challenge and a roadblock to the adoption of the technology. Previously, we have successfully developed reinforcement learning (RL) solutions toward addressing this issue.

Knee Motion Generation Method for Transfemoral Prosthesis based on Kinematic Synergy and Inertial Motion [PDF]
IEEE Transactions on Neural Systems and Rehabilitation Engineering
( Volume: PP, Issue: 99 ) pg 1, 2017 Previous research has shown that the effective use of inertial motion (i.e., less or no torque input at the knee joint) plays an important role in achieving a smooth gait of transfemoral prostheses in the swing phase. In our previous research, a method for generating a timed knee trajectory close to able-bodied individuals, which leads to sufficient ...

Structural Simulation of a Bone-Prosthesis System of the Knee Joint
Sensors, 2008 In surgical knee replacement, the damaged knee joint is replaced with artificial prostheses. An accurate clinical evaluation must be carried out before applying knee prostheses to ensure optimal outcome from surgical operations and to reduce the ...

Bouncy Knee in a Semi-Automatic Knee Lock Prosthesis [PDF]
Prosthetics & Orthotics International, 1986 The Bouncy Knee concept has previously proved of value when fitted to stabilised knee units of active amputees. The stance phase flex-extend action afforded by a Bouncy Knee increased the symmetry of gait and also gave better tolerance to slopes and uneven ground.

Total Knee Arthroplasty for Chronic Anterior Knee Dislocation
Clinical Medicine Insights: Case Reports, 2018 Background: The occurrence of chronic knee dislocation is rare. To the best of our knowledge, total knee arthroplasty for treatment of chronic anterior knee dislocation has not been reported. Method: This report describes 3 cases of chronic anterior knee
