The MyoPro Motion-G is the first powered orthosis to enable both elbow flexion/extension and grasping function. The innovative elbow-wrist-hand orthosis is based on decades of work in myoelectric orthotics and prosthetics, including building on myoelectric research conducted by the VA Medical Center, West Roxbury, Mass. in 1990.

The Motion-G is the latest innovation in the company’s MyoPro line, which enables people to initiate and control movement of a partially paralyzed arm using their own muscle signals.

“The Motion-G now makes it possible for people with upper extremity paresis to grasp and release, opening up new possibilities to manage daily tasks and live more independently,” said Myomo CEO Paul R. Gudonis.

Sensors built into the custom device detect EMG signals in the bicep/tricep and forearm. The signals are amplified when a user initiates movement, driving small motors that help flex and extend their elbow and open and close their thumb and fingers for 3-jaw chuck grasp capability. The device also enables users to articulate their wrist manually.

A clinical study underway shows promising early results, according to Dr. Stephen Page, principal investigator for the study. The study will measure the approximate changes in subjects’ ability to successfully perform functional tasks with the device.

“We expect that this study will demonstrate that wearing the Motion-G significantly improves the ability to perform valued daily activities, and that the amount of active movement that people are able to attain during these activities increases as a result of wearing the device,” Page said.

About Myomo, Inc.

Myomo, Inc., is a medical device company specializing in myoelectric orthotics for people with neurological disorders. The Company’s products help to restore function in individuals with neuromuscular conditions such as brachial plexus injury, traumatic brain injury, spinal cord injury, multiple sclerosis, ALS, and stroke.

The Company’s myoelectric orthoses have been clinically shown to help restore the ability to complete functional tasks by enabling individuals to self-initiate and control movement of their partially paralyzed limbs by using their own muscle signals.

The Myomo technology was originally developed at Massachusetts Institute of Technology in collaboration with medical experts affiliated with Harvard Medical School. Myomo, Inc. is a privately held company headquartered in Cambridge, MA.
