Concussion Balance Testing, Simplified

Leveraging the sensors in your device

Sway’s balance tests leverage the sensors already built into mobile devices. During testing, athletes hold the device securely while performing a series of balance stances. The mobile sensors capture subtle movements, and Sway’s algorithm analyzes these to generate a balance score. This method eliminates the need for additional equipment, making the process both convenient and reliable.
