Peripheral neuropathy is one of the major causes of sensation loss and significantly increases the risk of feet ulceration with potential limb loss. Alarmingly, up to 50% of diabetic neuropathy patients may not have subjective complaints.
The Prosenex Diagnostic Tool provides uniform patient screening for peripheral fiber neuropathy by graded temperature and vibration discrimination stimuli. The device will standardize the physical examination by medical professionals.
It establishes objective peripheral neuropathy screening across medical specialties and helps to overcome differences in medical professionals examination techniques. The device helps to follow longitudinal changes in patients’ health. The device may significantly improve patients’ compliance with medical advice by providing objective numerical data of the sensitivity status.
The device provides for two temperature pads. One pad is fixed at 25 °C while the other pad can vary from 15-40°C in 2 degree increments. 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 a standard frequency of 128Hz. 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.
