Design and Development of Prosthesis for Ultrashort Knee Stump

In this paper, an abstract is provided for a novel prosthetic suspension system designed, developed, and evaluated for ultrashort knee stumps. Some of the major drawbacks of already available prosthetic solutions are socket slippage, pressure discomfort, and limited range of motion for those who have ultrashort stumps. In this work, a vacuum-assisted suspension system (VAS) significantly increases the comfort, stability, and prosthetic fit. The system uses a loop control system which regulates pressure to a microcontroller and uses machine learning to improve the real-time control for human activity recognition with 95.13% accuracy and 2% error for pressure regulation. This solution offers potentially encouraging advances in prosthetics technology for those with transtibial amputations.
