The ForcePlates measure as little as the touch of a finger through to full standing weight-bearing. Multiple ForcePlates can be used to increase the data collection options. Use of two ForcePlates provides easy measurement of bilateral upper or lower limb weight distribution. Combining four ForcePlates allows continuous dynamic measurement of anterior/posterior and mediolateral weight distribution.

There are two model options - the FP3 and the FP4. Each ForcePlate consists of a sandwich of two uniform precision metal plates, with four load cells mounted between them. The vertical component of the total reaction force is measured independent of where it is applied over the surface of the plates.

Both FP3 and FP4 ForcePlates can connect to Biometrics Ltd. interfaces – DataLITE, DataLOG, DataLINK, or K800 Amplifier. It can also be connected to various 3rd party interfaces or be combined with EMG, joint goniometry movement data, or other sensor inputs into one simple system.

The BF8/ BF10 BaseFrame is designed to hold ForcePlates in a variety of positions on the floor to accommodate a wide range of subject sizes with different stance widths.

The BaseFrame has cutouts which usually hold 2 or 4 ForcePlates and comes with 8 blanks to fill any unused cutouts. The integral handle makes the BaseFrame easily portable and the non skid strips on the bottom prevent sliding on floors or carpet.

The modularity of the ForcePlates provides maximum versatility of applications such as:

  • Upper extremity – unilateral or bilateral
  • Seated balance
    • On the chair/wheelchair seat
    • Under the chair legs
    • Under wheelchair wheels
  • Incorporation into other equipment – for example into stair steps to measure weight bearing during stair climbing
  • Lower extremity
    • Unilateral or bilateral
    • Single axis
      • Mediolateral (Left/right)
      • Anterior/posterior (Front/back)
    • Multi-axial
      • Simultaneous Mediolateral (Left/right) and Anterior/posterior (Front/back)
      • Sit to stand – use 2 ForcePlates on the seat and 2 or 4 on the floor
