Catalepsy is a robust behavior, and the lack of standardization does not usually hinder its actual detection. The most common method for assessing catalepsy behavior has been the elevated bar test. In this test an animal is placed with its forelimbs on the bar that is elevated. Cataleptic criteria vary depending upon the study, but in the most cases the amount of time that either one or both forelimbs remain on the bar is code as cataleptic time

Single timer for both limb
Dual timer for left and right limb
Catalepsy is usually defined as the state of persisting in an unusual posture, and can be characteristic of neurological disorder such as Parkinson’s disease and schizophrenia. The typical catalepsy test consists of placing an animal into an unusual posture and recording the time taken to correct this posture. This time is regarded as an index of the intensity of catalepsy.

Features
The catalepsy bar test apparatus is a convenient apparatus for automating catalepsy scoring. This chamber can be used with both rats and mice. The chamber features a removable bar that can be positioned at any one of eight heights, ranging from 1.7” from the chamber floor up to 8.7” from the
chamber floor. This flexibility allows for the use of animals of different sizes (mice to rats), as well as placing animals in various positions. Also, the catalepsy chamber contains two different contact rods of diameter 3/16” and ½”. Again, this flexibility allows for the use of both mice and rats, as well as animals of different sizes within a given species.
