Transradial amputees or below elbow amputated people
Description and Functionality
Elbow region has many muscles that descend towards the wrist, palm and fingers in the form of tendons. People with below elbow amputation have remnant muscle activity that can be tapped using EMG sensors. Based on this principle, a radial prosthesis with higher degrees of freedom (including each finger) and a promising sensory feedback mechanism that mimics the functionality of a real arm has been developed by identification and isolation of tangible electrical impulses for various activities of the hand. A highly efficient sensory feedback mechanism for holding the objects, identifying the shapes and weights along with temperature identification are the important components of the developed prosthetic arm.
State-of-the-art
Low cost, non-invasive, biosensor interface that primarily uses the residual EMG activity to stimulate all the five prosthetic fingers along with the wrist and the palm so it can handle any given scenario like a real arm.
Stage of Development
The prototype is under consideration by Artificial Limb Manufacturing Corporation of India (ALIMCO) for commercialization.
