Description: The Tail Flick Test is used to measure a rodent's sensitivity to changing temperature. The test subject is restrained in a conical polypropylene tube with an opening through which its tail is exposed. In one version of the test, the tail is exposed to a heat lamp and the amount of time taken for the animal to move (flick) its tail away from the heat is recorded. Another version of the tail flick test is the water immersion method. In that test, approximately one third of the rodent's tail from the tip is immersed into a 52OC � 0.2OC water bath and the amount of time until the rodent flicks or removes its tail is recorded.
Purpose: Both the heat lamp and water immersion versions of the test are used to assess spinal nociception.
