Transforming the treatment of movement disorders with intelligent, wearable robots.
We envision a world where children and adults with movement challenges lead healthy, productive and socially satisfying lives.
50 million people in the US have a physical disability that limits their mobility, negatively impacting their health. Many of these individuals are unable to walk unassisted or go up and down stairs.
The Current Solution
Physical Therapy (PT) is essential for treating movement disorders and there is a strong dose-response relationship between the amount of therapy and improvements in mobility.
Unfortunately, most individuals do not receive enough PT and the delivery of PT can be inefficient, limiting the dose and positive changes in mobility.
There is currently no viable way to provide a sufficient dose of active gait training that will lead to long-term improvements in mobility.

Ground Breaking Results
Taken at the beginning and end of a 3x/week for 4-weeks intervention, these videos show the benefit of using the RA2D in Resist-to-Restore mode. Note the increase in self-selected walking speed and improved posture. The child is not using the RA2D in these videos.

Co-founders Zach Lerner and Ray Browning met in 2011 at Colorado State University. Since that time, Zach and Ray have been focused on understanding and optimizing pediatric mobility. As former elite athletes, they both have a passion for movement and the vision that all individuals have physical experiences that allow them to see and achieve their potential. Over the last several years, Zach has created robotic assistive devices that offer a lightweight, portable and effective way to improve mobility in children with Cerebral Palsy. These devices are the foundation for BiOMOTUM.
Our mission is to improve mobility and rehabilitation outcomes in individuals with movement disorders. We aim to accomplish this mission by leveraging a user-centered design approach, gathering insight from affected individuals and clinicians, to create, produce and distribute intelligent, holistic and engaging wearable systems. Our patent-pending technology is built on a foundation of rigorous clinical research. Our systems are designed to improve neuromuscular function and quality of life across the lifespan. We have a functional device that has proven mobility benefits.
