Temperature Discrimination

The device provides for two temperature pads. One pad is fixed at 25 °C while the other pad can vary from 15-23°C in 2 degree increments in the cold mode and 27-40°C in 2 degree increments in the warm mode . After the variable temperature is set, each pad is touched to the same area in succession to determine if the patient can discern the difference. Small fiber vitality or neuropathy can be screened and tracked based upon the smallest temperature difference the patient can discern to establish a baseline and detect changes over time on various areas of the foot or other extremities.



Vibration Sensitivity

The device actuates a tip which vibrates at 5 different amplitudes at the frequency of a standard tuning fork. Large fiber health or neuropathy can be screened and tracked based upon the lowest amplitude that the patient can sense to establish a baseline and detect changes over time on various areas of the foot or other extremities.
