Purpose and goal

Currently, leg prostheses operate independently from the patient´s neuromuscular system. This separation between the biological and mechatronic control systems results in limited functionality, as well as poor physiological adaptation to the artificial limb. We aim to provide, for the first time, natural neuromuscular control and sensory feedback for robotic leg prostheses. In this project, we aim to clinically verify a novel implant technology to achieve this goal.

Expected results and effects

Ever since the invention of implantable devices, a reliable and long-term stable communication with the outside of the body has been a challenge. In prosthetic limbs, it has prevented the utilization of neuromuscular interfaces for intuitive neural control. In this project, we aim to resolve this long-standing problem with a clinically viable product that will open a new market of high-end solutions for leg prostheses. The successful implementation of this project will considerably boost Integrum’s products, and will place our consortium as the world leader in limb replacement.

Planned approach and implementation

This is a collaborative project between Chalmers University of Technology (CTH), Sahlgrenska University Hospital (SUH), and Integrum AB. The three partners have a shown successful collaboration in the past with the development and implementation of an analogous technology for upper limbs. The Biomechatronics and Neurorehabilitation Laboratory, Department of Electrical Engineering, CTH, coordinates this project and bi-weekly meetings will be held between the partners to ensure that the project is executed according to plan.
