Tip-Therm is an early diagnostic instrument for distal symmetric Polyneuropathy.

     Tip-Therm is designed to give the clinician and patients a convenient and

easy method of testing. Tip-Therm is made of special polymer and metal alloys.

The polymer side feels warmer and the metal alloy side cooler due to the different

thermal conductivity property of the materials. The clinician place the two flat

surfaces on the patient's foot at irregular intervals while the patient should be keep

the eyes closing. If correct answers are given when the clinician asks whether it

feels cold or not so cold, it may presume that the patient's temperature perception

is functioning well.
