To make fun and innovation a part of physical therapy, and encourage patient engagement in the rehabilitation experience. We utilize mobile health to deliver innovative, user-friendly devices and mobile applications to supplement physical therapy rehab and improve health outcomes.

mTrigger began as a simple idea: improve the physical therapy experience for patients and therapists. Biofeedback has been a trusted physical therapy modality for decades, but despite its many accolades, its delivery system has been left in the 20th century. After thirty years in the field, PT Russ Paine knew that the time was right to introduce a better way for patients to engage in their rehabilitation. Teaming up with laser therapy specialist and serial entrepreneur, Brian Pryor, they were eager to get the ball rolling.

Cue: University of Delaware’s Office of Economic Innovation & Partnerships (OEIP) Spin In Program. With both founders being proponents of hands-on education, this opportunity to work with an interdisciplinary team of undergraduates was a perfect fit. The project began in the fall of 2014 and accumulated team members and experience during its 18-month incubation. Prototyping of the mTrigger Biofeedback System continued through the spring and summer of 2015, with the development team making technological advances and learning to embrace the entrepreneurial spirit along the way.

mTrigger, LLC, was incorporated in 2015 and has since been working along with its development partners through the commercialization and design refinement processes. mTrigger’s Individual Unit and Clinical Bundle products launched in early 2018, and the team continues to make improvements to fit the needs of the physical therapy market.
