Force Distribution

FDM-T System for Gait and Stance Analysis

The basic system FDM-T consists of a treadmill ergometer with an integrated, calibrated measuring sensor. The sensor element consists of high-quality capacitive force sensors. On an area of 150 x 50 cm the sensor unit consists of more than 5000 pressure / force sensors. Using a technology especially developed by Zebris the movement of the treadmill belt is automatically compensated so that completely stable gait and roll-off patterns can be analyzed.

The display of all measuring results is available in real-time utilizing commercially available PC's. Feedback control of the force on the extremities is also possible. The software also provides a "signal viewer" which displays all measuring variables in slow motion and is completely synchronized.

In the standard arrangement all FDM-T systems are equipped with video-synchronization output for time-synchronization with the video-camera. The optional camera module consists of a high-quality video camera with stand, a wide angle lens as well as all cables necessary for operation, synchronization and software.

The time synchronization using the optionally available cordless radio adapter DAB is accomplished via an infrared interface. The radio adapter is connected to the PC via Bluetooth interface and can be linked with up to eight Noraxon EMG amplifiers or inertial sensors which enable the system to perform kinematic motion analysis whereby a skeleton model is animated.
