Biometrics Force Plates FP3 and FP4
The Biometrics Ltd range of Force Plates are focused to the needs of the researcher providing high precision, versatility and ease of use. Direct connection to the Bluetooth DataLOG, the tethered DataLINK or the tethered General Amplifier K800 enables data capture and analysis of vertical component of reaction force in a wide variety of applications.
2 models available:
- Force Plate FP3 - 100 Kg full scale output
- Force Plate FP4 - 250 Kg full scale output
Each Force Plate consists of a sandwich of 2 uniform precision metal plates, with 4 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.
The relative light weight and small geometry of the plates aids in a wide range of upper and lower limb applications. The Force Plates measure as little as the touch of a finger through to full standing weight bearing. Multiple Force Plates can be used to increase the data collection options. Use of two Force Plates provides easy measurement of bilateral upper or lower limb weight distribution. Combining 4 Force Plates allows continuous dynamic measurement of anterior/posterior and mediolateral weight distribution. The optional Base Frame allows the position of the Force Plates to be varied to accommodate different stance widths - from paediatrics to adults.
The modularity of the Force Plates 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
- Lower extremity
- Single axis
- Mediolateral (Left/right)
- Anterior/posterior (Front/back)
- Simultaneous Mediolateral (Left/right) and Anterior/posterior (Front/back)
- Sit to stand - use 2 Force Plates on the seat and 2 or 4 on the floor
- Incorporation into other equipment - for example into stair steps to measure weight bearing during stair climbing
Used with the Biometrics Ltd instrumentation - DataLOG, DataLINK, or K800 - the output from the FP3 and FP4 can readily be combined with EMG, joint goniometry movement data, or other sensor inputs into one simple system.
