Developed as part of a project by researchers at Chalmers University of Technology in Sweden and prosthetic company Integrum AB, this artificial joint is helping restore basic function for forearm amputees. The current range of prosthetics utilizes a motorized wrist rotator that performs decently. However, because of the designs of the prosthetics, users cannot activate the wrist and hand at the same time, and the options lack sensory feedback.
This is where this new artificial joint comes in. The new prosthetic utilizes osseointegration, which connects a prosthesis directly to a skeleton. The use of this type of implant serves as an interface between the new artificial joint which means the prosthetic can move more naturally and allows users to have intuitive control and sensory feedback.
