Comparisons of robotic ankle prosthesis and conventional prosthesis in below knee amputee

A Robotic Prosthesis for an Amputee Drummer

The design and evaluation of a robotic prosthesis for a drummer with a transradial amputation is presented. The principal objective of the prosthesis is to simulate the role fingers play in drumming. This primarily includes controlling the manner in which the drum stick rebounds after initial impact. This is achieved using a DC motor driven by a variable impedance control framework in a shared ...

Ankle-knee prosthesis with active ankle and energy transfer: Development of the CYBERLEGs Alpha-Prosthesis

This paper presents the development of the CYBERLEGs Alpha-Prototype prosthesis, a new transfemoral prosthesis incorporating a new variable stiffness ankle actuator based on the MACCEPA architecture, a passive knee with two locking mechanisms, and an energy transfer mechanism that harvests negative work from the knee and delivers it to the ankle to assist pushoff. The CYBERLEGs Alpha-Prosthesis...

Simplified, low cost below-knee prosthesis.

Problems are encountered in using standard prostheses in developing countries, especially when the prostheses need repair and the amputees cannot come back to the workshop. Very simple, low cost and durable prostheses can solve this problem. The solution described has worked well with villagers in some rural areas of Thailand, where the inexpensive prosthesis permits walking bare-foot and throu...

Prosthesis-free solution for below-knee amputations.

The Ilizarov fixator can be used as a bone regenerator to correct limb-length discrepancies in patients who require limb lengthening.A 17-year-old man presented with 12 cm of left lower-limb shortening and amputation at the left mid-forefoot region, which was the result of severe burns of the left lower limb at 2 years of age. The burns damaged the distal femoral, proximal, and distal tibial ph...
