AMTI Biomechanics Measurement System (Optima-BMS)

AMTI’s Biomechanics Measurement System (Optima-BMS) is Optima technology in the most affordable package.

Optima is a revolutionary development in force plate technology, offering a 10-fold improvement over any other force platform system currently available. The result is a force plate that is easily more accurate – right to the edges – than any other competitor system. The Optima-BMS is second only to the Optima High Performance Series (HPS).

Only the Optima HPS and BMS platforms conform to the new technological standard for gait and biomechanical force measurement systems, which is the ASTM F3109-16 verification standard. Read more.

AMTI have recently added their large surface area platforms to the Optima-BMS series, so all standard AMTI force platforms, from the 400x600mm to the 900x900mm, are now part of the Optima family and undergo AMTI’s patented Optima calibration process. This process produces even more force plates that are more accurate and more repeatable from edge to edge than ever before.

Optima-BMS Specifications

The Optima precision calibration process involves up to 4000 measurements taken along a high-density grid that covers the entire platform surface. Multiple loads are applied at up to 400 locations using a precision machine capable of maintaining absolute positioning accuracy of 0.005mm, which is certified by The Association for Manufacturing Technology.

This process results in market-leading specifications, including:

  • Centre of pressure (COP) error typically of <0.5mm
  • Crosstalk, % app load, typically of ± 0.2%
  • Measurement accuracy, % applied load typically ± 0.5%
