Computational Modelling of a Smart and Energy Efficient Prosthetic Foot
A collaboration between Swansea University and Cardiff University
Initial and optimal prosthetic designs.
A prosthetic foot is effectively a dead weight that is not supported by human muscles and nervous system. As a result, transtibial amputees tend to feel that the prosthetic foot is uncomfortably heavy, even when it weighs only one quarter of the corresponding weight of the human leg. This mass imbalance has an influence on the kinematics of gait, and the human desire to maintain symmetric walking gait irrespective of imbalances can result in sub-optimal consumption levels of human energy.
We will validate the model using in vivo measurement of gait, along with functional scores, in collaboration with Cardiff University.
The model will enable the development of improved prosthetics and orthosis.
Swansea University has developed a passive dynamics model for walking with different masses for a prosthetic and an intact foot. The challenge is to extend this model with a predictive dynamics model that is linked with neuromuscular data and retains as many passive elements as possible, to maximise the human energy efficiency.Back
