Portable Balance and Postural Sway Platform  Unprecedented Accuracy Better Data for Better Science  Plug & Play USB Interface OVERVIEW AMTI's AccuSway Optimized™ multi-axis force platform is a portable solution for quantifying human balance and postural sway. The AccuSway’s innovative, patented design is accurate, economical, and easy to use with AMTI's powerful NetForce, Balance Clinic and Balance Trainer software. The plug & play USB interface automatically synchronizes multiple platforms and eliminates external power supplies. AccuSway Optimized attains unprecedented levels of accuracy for measuring Center of Pressure, forces and moments, as well as dramatic reductions in crosstalk. This breakthrough in performance is made possible by AMTI’s unique precision grid calibration technology. This new level of accuracy enables clinicians to make better patient measurements, and enables researchers to perform better science based on more accurate input data. The levels of accuracy achieved with AccuSway Optimized are a quantum leap over previous technologies used in the biomechanics industry. SYSTEM FEATURES Multi-Component Measurement Forces: Fx, Fy, Fz Moments: Mx, My, Mz Digital Output Plug & play USB 2.0 interface automatically synchronizes up to 12 AccuSway Optimized force platforms. High Overload Protection One-piece sensor element provides extremely high overload protection on a

Portable - No Mounting Necessary Just place the platform on a flat surface and use. UNPRECEDENTED ACCURACY Convenient Surface Grid A grid on the surface of the platform provides base-of-support coordinates which can be combined with the balance data, allowing the center-of-pressure (COP) to be plotted relative to the subject's foot position. AMTI’s precision grid calibration technology optimizes each AccuSway Optimized force platform’s accuracy. By taking 1275 measurements in a grid pattern and using the points for calibration, enormous improvements in accuracy and reductions in crosstalk...
