Can an Array of Micro-electrodes Implanted in a Human Nerve Record Neural Signals and Provide Feedback?

Can an Array of Micro-electrodes Implanted in a Human Nerve Record Neural Signals and Provide Sensory Feedback Useful for Controlling a Prosthetic Device?

Sponsor

University of Utah

Enrollment

3 participants

Start Date

Dec 21, 2020

Study Type

INTERVENTIONAL

Conditions

Amputation

Summary

The investigators will investigate the device feasibility of human peripheral nerves and muscles recording and stimulation using percutaneous Utah Slanted Electrode Arrays (pUSEAs) implanted into residual peripheral arm nerves and EMG electrodes implanted in the residual muscles of patients with limb amputations in order to determine the ability of the HAPTIX (Hand Proprioception and Touch Interfaces) System to control an upper-extremity prosthesis, and to provide a sense of cutaneous touch and muscle proprioceptive feedback to the amputee.

Eligibility

Min Age: 18 YearsMax Age: 65 Years

Plain Language Summary

Simplified for easier understanding

This study is testing whether tiny electrodes implanted in a nerve of someone who has had an arm amputation can detect nerve signals and provide sensory feedback. The goal is to help people with upper limb amputations feel sensations through a prosthetic arm, making it more natural to use. You may be eligible if: - You are between 18 and 65 years old - You have had a traumatic or elective amputation of one or both arms at or below the elbow You may NOT be eligible if: - You are currently incarcerated - You are pregnant - You are unable to give informed consent - You have a psychiatric condition that would affect study participation - You have medical conditions that significantly increase the risk of general anesthesia Talk to your doctor to see if this trial is right for you.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.
