Science

Some of the
research we use.

ROMRx is opinionated software, and those opinions draw on published work in range of motion, injury risk, training response, and athletic performance. Below is a sample of the research behind ROMRx. It is not a complete bibliography, and it is not proof of any particular result.

Range of Motion Research

Not medical advice. ROMRx is a fitness and mobility tool, not medical diagnosis or treatment.
