ForcePlates
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:-
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 & 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.
Both the FP3 & FP4 connect to Biometrics Ltd instrumentation – DataLOG, DataLINK, or K800 - using the H2000 cable. The output from the FP3 & FP4 can readily be combined with EMG, joint goniometry movement data, or other sensor inputs into one simple system.
The Biometrics Ltd Force Plates can also be connected to various 3rd party instrumentation. Please contact us for full technical information.
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
- Unilateral
- 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 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
BaseFrame BF8
The BF8 BaseFrame is designed to hold the FP3 ForcePlates in a variety of positions on the floor to accomodate a wide range of subject sizes with different stance widths. The BaseFrame has cutouts which usually hold 2 or 4 FP3 ForcePlates and comes with 8 blanks to fill any unused cutouts. The integral handle makes the BF8 BaseFrame easily portable and the non skid strips on the bottom prevent sliding on floors or carpet.
