Numbers with a white background indicate a test result from a foot with a freezing cold injury. Bold numbers indicate a test value that differs >2SD from the mean reference value.
1
Results presented as a sensibility index for all frequencies combined (8, 32, 125 and 500 Hz). A lower value indicates reduced sensibility to vibration stimuli.
2
Values presented are the difference in degrees Celsius from baseline temperature to detection temperature. A higher temperature value indicates reduced sensibility.
