During his 30 years of military service, retired U.S. Army Reserve Major and physical therapist Jeff Frankart treated injured U.S. and NATO service members, including serving as Chief of Chronic Pain Physical Therapy at Landstuhl Regional Medical Center in Germany. Facing thousands of service members who needed to regain function efficiently, Jeff developed a progressive, movement-based rehabilitation approach that required minimal equipment and could be adapted for individuals and groups.
After retiring from military service and relocating to Florida, Jeff encountered a different population—but another urgent problem.
In the clinic, he began seeing older adults struggling with declining balance and mobility, neurological conditions, and falls. The challenge was no longer returning soldiers to duty. It was helping people maintain the physical capabilities needed to remain safe, mobile, and independent as they aged. His Jupiter, Florida, practice subsequently expanded its work in balance, movement, and neurological rehabilitation.
Jeff recognized that many people needed more than conventional strengthening. They needed a way to progressively challenge the nervous system, retrain functional movement and balance reactions, and practice at a level appropriate to their abilities.
That need became the foundation for Mobility-X.
Today, Mobility-X carries those principles forward through Neuroplastic Functional Integration (NFI) - a progressive treatment approach that develops reflexes, balance, mobility, and safety while meeting people where they are, from a rolling walker to two canes, one cane, and ultimately no assistive device.
What began as a solution to a clinical problem has grown into a broader mission:
"Give rehabilitation professionals a system to train movement differently and provide people with the tools to preserve their independence for life."
Mobility-X is the home of the Neuroplastic Functional Integration (NFI) system, providing rehabilitation professionals with education and training to learn, understand, and apply the NFI approach in clinical practice. Through professional courses, hands-on training, clinical resources, and practical exercise progressions, Mobility-X helps clinicians translate NFI principles into individualized interventions for balance and functional mobility.
Mobility-X also extends NFI beyond the clinic. Through its patient platform, individuals can access structured at-home balance programs featuring NFI-based exercises, enabling them to continue practicing purposeful movement and balance activities in an accessible home environment.
ONE PLATFORM. TWO PATHWAYS.
OUR VISION
To enable people as they age and those living with neurological conditions to actively develop and preserve the reflexes, balance, and mobility needed for safe, lifelong independence.
OUR MISSION
To translate the science of neuroplasticity into functional movement training for rehabilitation specialists and people as they age, and to preserve lifelong independence for people living with neurological conditions by enhancing reflexes, balance, mobility, and safety.
