24/7 motion analysis lab in your pocket

OneStep provides real-time, easy-to-understand feedback that puts patients in control of their recovery and equips therapists with the clinical evidence they need to make the right decisions.

Utilizing the smartphone to the max

Until today, the only way to accurately measure a patients' motion was to send them to a full analysis in a motion lab - an endeavor that is extremely costly, inaccessible, and requires hours of analysis time. As an alternative, many providers defer to subjective tools, such as pain questionnaires. While offering some insight, these tools are neither objective nor accurate enough to measure a patient's progress and optimize their recovery. Moreover, neither option allows providers to assess patients' movement in real-life, outside of the clinic or lab.

OneStep introduces a first-of-its-kind technology for delivering lab-level motion analysis from any smartphone - bringing immediate, easy-to-understand, around the clock feedback directly to patients and their providers. With OneStep, physical therapy extends beyond clinic walls as therapists can treat and monitor patients remotely between sessions, leading to better clinical decision making and better outcomes.

Gait is now a vital sign

Gait is a vitally important indicator of and predictor of a person’s musculoskeletal, cardiovascular, cognitive and neurological health. OneStep’s gait analysis is the first to capture gait in a natural setting, and its ease of use contributes to making the OneStep gait database the largest and most comprehensive in the world. This goes beyond physical therapy, providing countless opportunities for research around, and development of, new medical treatments and devices.

A new standard for gait measurement

The OneStep Walk Score was developed to provide feedback directly to patients in a way that boosts their motivation immediately. It is easy to understand and allows patients to learn from every walk they take. The progress updates and quantifiable measurements help them to better understand their impairments, their therapeutic goals, and to feel good about their progress along the way -- which increases patient satisfaction and compliance. OneStep uses the Walk Score in tandem with industry-standard subjective scales (such as the LEFS) to establish a new gold standard for measuring patients progress.

Clinical progress reports delivered on-demand

We designed the OneStep platform with providers in mind. While our technology collects and analyzes the 24/7 gait data, our platform allows providers to easily generate progress reports about any patient, at any time. Available through the app or web. Surgeons and physical therapists utilize our progress reports to view a patient’s recovery trajectory on the whole, to share in discussion with patients, and to make long-term clinical decisions.
