Temperature threshold testing investigates the function of small nerve fibres responsible for temperature sensation. A metal cube will be secured at the feet, and sometimes at the hands. This cube alternates between warm and cold temperature. By pushing a button the patient indicates whether changes in temperature are felt.

The test is painless and lasts about 30 minutes.

The test usually is abnormal if small nerve fibre function is impaired. The test can also be abnormal in other conditions of the nervous system that impair sensation.

More information can be found in the brochure temperature threshold testing (in Dutch).
