Enhancing hand movement control for amputees using nerve signals

Official title: Improving hand kinematic predictions from implanted EMG in humans and monkeys

Funded at University of Michigan at Ann Arbor · NIH-10979725 · Data updated 2026-11-12

This study is working on a new way to help people with upper limb amputations control prosthetic hands more naturally by using signals from their nerves, making it easier for them to move their fingers and wrists just like they would with real hands.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals with upper limb amputations who are seeking improved control over their prosthetic devices.

Less likely to help

Patients with lower limb amputations or those who do not use prosthetic devices may not benefit from this research.

What this research studies

This research focuses on improving the control of prosthetic hands for individuals with upper limb amputations by utilizing electrical signals from nerves. The team has developed a method called the Regenerative Peripheral Nerve Interface (RPNI), which allows for better signal acquisition from nerve fascicles. By employing advanced deep learning techniques, the project aims to enable continuous and simultaneous control of finger and wrist movements in both humans and monkeys. This innovative approach seeks to restore more natural hand functions for amputees, enhancing their ability to perform daily activities.

Why it matters

Potential benefit: If successful, this research could significantly improve the functionality and usability of prosthetic hands for amputees, leading to greater independence in daily life.

How similar studies have gone: Previous research has shown promise in using similar deep learning techniques for brain-machine interfaces, indicating potential success for this novel approach.
