Pitt+Me EMG Recording for Control of Artificial Limbs - Forearm/Wrist Amputation


STUDY BASICS

Do you have an amputation at the forearm or wrist that occurred at least one year ago? Are you between 18-70 years old? If so, you may be able to take part in a research study to help better understand arm movement in order to develop new artificial limb technologies for people with amputations. Compensation provided.


STUDY PURPOSE

The loss of an upper limb can sometimes make it difficult to function and perform daily life activities. Many people with amputations have artificial limbs, but controlling these types of devices is not always easy and people often stop using them.

The purpose of this study is to use electromyography (EMG), which measures the electrical activity of muscles, and other measures, to better understand arm movement in people with and without upper limb amputations. Researchers hope their findings will help in the development of an artificial limb with better quality, speed, and range of motion.


COULD THIS STUDY BE RIGHT FOR YOU?

•    Ages 18-70
•    Have an amputation of at least one forearm or wrist
•    At least 1 year post-amputation
•    Not pregnant


WHAT PARTICIPANTS CAN EXPECT

Participation involves at least 1 in-person visit lasting 8 hours. Study procedures include completing questionnaires and having electromyography (EMG) electrodes placed on and under the skin of your arm. With the EMG electrodes in place, you will be asked to watch videos of various arm movements, interact with a robot, imagine performing a series of arm movements such as reaching, grasping, and moving objects, and have some movements measured with non-invasive motion tracking equipment. Some participants will be asked to return for a second in-person visit that will last 8 hours.

MEET THE RESEARCHER


Robert Gaunt

Robert Gaunt, PhD, is an assistant professor in the Department of Physical Medicine and Rehabilitation at the University of Pittsburgh. Dr. Gaunt received his PhD in Biomedical Engineering at the University of Alberta in 2008 and his postdoctoral training at the University of Pittsburgh. He maintains a secondary appointment with the Department of Bioengineering. Dr. Gaunt’s primary research interests are in the area of sensorimotor control and developing advanced neural interfaces with the brain and peripheral nerves for sensory restoration and motor control. He also works on developing methods to improve bladder function using electrical stimulation of the spinal cord and peripheral nerves. The goal of this work is to understand how humans normally accomplish complex sensorimotor tasks, test these principles using neuroprosthetic technologies, and ultimately leverage this knowledge to develop devices to restore and improve function.
