Description

The Tail Flick test, introduced by D’Amour and Smith in 1941, was designed to assess pain responses in rats. In their study, they explored how various substances, including cobra venom, affected pain perception. Unlike the Hargreaves Plantar test, which applies heat to the center of a rodent’s hind paw, the Tail Flick test involves applying heat to the rodent’s tail. The results of the Tail Flick test can vary based on the specific strains and species of the rodents, as well as their adaptation to being restrained.

There are two primary methods for conducting the Tail Flick test. One method involves immersing the tail in water heated to a specific temperature, while the other applies radiant heat directly to a portion of the tail. Proper acclimatization to handling is crucial for both methods. Similar tests to the Tail Flick include the Hargreaves Plantar test, the Hot-Cold Plate test, and the Thermal Gradient test.

Apparatus and Equipment

For the water-immersion version of the Tail Flick test, no specialized equipment is needed. In this method, it is essential to keep the water bath at a consistent temperature for the duration of the test. Conversely, the direct heat stimulus variant requires an analgesia meter, which is a specialized device. This setup includes a restraining tube that gently holds the subject in place while allowing access to its tail, a radiant heat source that delivers precise heat, and a timer to measure the response.

Training Protocol

Before beginning the experiments, the apparatus must be thoroughly cleaned. The performance can be recorded and observed using a tracking and recording system such as the Noldus EthoVision XT and ANY-Maze.

Strengths & Limitations

Summary and Key Points

  • Tail Flick test was first described by D’Amour and Smith in the year 1941.
  • Tail Flick test is similar in concept to the Hargreaves test. The heat stimulus is directed on the part of the subject’s tail rather than the plantar surface.
  • Tail Flick test requires restraining of the subject.
  • Tail Flick test can be performed either using an analgesic meter or using a water bath.
  • Painting the portion of the tail, to be tested, black allows greater absorption of the heat,
  • Spinally transacted subjects may show spinal reflex behavior rather than that induced by pain.
  • Subject’s motor functionality can also impact withdrawal responses.
