Everything is software adjustable in a very userfriendly way, the filters, gain, samplefrequency. The BFU is used to give direct feedback to the patient about his gait. This is done by setting a minimum and a maximum level of force per area of the foot. In this way, the patient can adapt his gait immediately. Rehabilitation can be accelerated because of direct feedback .
Patients can learn to use a prosthesis more effectively .
The force is measured by two force transducers that are built into a slipper. This slipper is worn over the shoe. The force threshold can be adjusted using a weightscale. When the pre-set maximum is exceeded, an alarm signal sounds. The pitch of this alarm signal varies with the amount of overload, so the amount of overload is clearly audible.
