Balance testing has never been easier. No bulky forceplatforms, harnesses or guessing at errors. Sway provides the most accurate and validated mobile software for measuring postural stability all from the mobile device you or your athlete already have.
Sway measures stability using the built-in motion sensors of any mobile device or tablet to quantify postural sway. While the device is pressed against the chest, a proprietary motion analysis algorithm calculates stability and provides an easy to understand value on a 100 point scale with 100 being completely stable and 0 being unstable.
Sway has been repeatedly validated against force platform technology, the current gold standard for postural sway assessment. Sway was also better at differentiating between progressively more difficult balance conditions in third party research studies.
Accuracy and consistency are both critical to the value of Sway‘s balance product. Reliability was shown in clinical studies analyzing test-retest variability in independent research studies of 30, 57 and 75 subjects. These results demonstrated strong test-retest reliability after an initial familiarization trial.
The Sway Balance assessment has shown strong agreement (r > 0.83) with the Balance Error Scoring System (BESS) in laboratory settings, however the low inter-rater reliability associated with BESS make it a challenge to implement. Sway is an effective sideline tool due to its objective metrics, simple user interface and the time it takes to complete a test.
Sway Balance is classified as a FDA cleared Class II medical device. Sway Balance is intended for use to assess sway as an indicator of balance. Individual suitability for assessment must be judged on a case by case basis, by a qualified individual including those certified and/or licensed in their state to prescribe and/or use balance devices such as certified athletic trainers and coaches, physical therapists, nurses and physicians.
Sway Balance is a medical device and should only be administered with a full understanding of the testing procedure in a controlled environment on a flat, hard surface to ensure test repeatability. Sway Balance does not identify the presence or absence of clinical diagnoses, and is not intended as a stand-alone or adjunctive diagnostic device.
Sway Balance is contraindicated for balance assessment of hospitalized patients and individuals with compromised balance.
