Stiffness Analysis of Above Knee Prosthesis

International Journal of Intelligent Systems and Applications in Engineering, 2019
While a healthy human walks, his or her legs mutually perform good repeatability with high accuracy. This provides an esthetical movement and balance. People with above knee prosthesis want to perform walking as esthetical as a healthy human. Therefore, to achieve a healthy walking, the above knee prosthesis must provide a good stiffness performance ...

Biomechanic and Energetic Effects of a Quasi-Passive Artificial Gastrocnemius on Transtibial Amputee Gait

Journal of Robotics, 2018
State-of-the-art transtibial prostheses provide only ankle joint actuation and thus do not provide the biarticular function of the amputated gastrocnemius muscle.

A systematic review of the evidence for single stage and two stage revision of infected knee replacement [PDF]

, 2013
BACKGROUND: Periprosthetic infection about the knee is a devastating complication that may affect between 1% and 5% of knee replacement. With over 79 000 knee replacements being implanted each year in the UK, periprosthetic infection (PJI) is set to ...

Continuous-Phase Control of a Powered Knee–Ankle Prosthesis: Amputee Experiments Across Speeds and Inclines

IEEE Transactions on robotics, 2018
Control systems for powered prosthetic legs typically divide the gait cycle into several periods with distinct controllers, resulting in dozens of control parameters that must be tuned across users and activities.

Responsive Polyelectrolyte Brushes in Applications: Functions, Stimuli, and Design Considerations

Advanced Materials, EarlyView.
With advances in the synthesis of polyelectrolyte brushes, these coatings of surface‐grafted chains find uses in an increasing number of applications. This review summarizes three core aspects of these brushes: how they introduce functionality to surfaces; how external stimuli influence their properties; and what practical considerations should be ...

Study on Gait Efficiency and Energy Cost of Below Knee Amputees After Therapeutic Practices [PDF]

, 2011
An earlier research advocated that a below knee amputee (BK) with conventional trans-tibial prosthesis attains higher gait efficiency at lower energy cost with therapeutic practices of proper time and co-ordination in compare to normal subjects of ...
