RotaRod for Mice and Rats

Product Code:47650/47750

The RotaRod is a simple test to assess motor function and coordination in rodents. Motor coordination or fatigue can be evaluated by measuring the time the animal stays on a rotating rod before falling. The Rod can rotate at constant, accelerating, rocking (back and forth) or through complex acceleration/deceleration ramps, thanks to the included PC software XPad.

The Ugo Basile RotaRod is the 1st and original, invented after the Dunham and Miya method (1957) and today has more than 6,200 citations in the literature. Ugo Basile RotaRod comes in a mouse 5-lane version, in a Rat 4-lane version and in a “Large Rat” version, plus Rod Adapters to enlarge the diameter of the rod and Complex Wheels to add a complexity element for the animal to be tested.

As the inventor of the RotaRod, we continue to improve our best-selling and gold standard device for motor function and coordination by developing new accessories and technologies to change the complexity and increase the sensitivity of the experiment.

The rotarod test, invented by Dunham and Miya (1957) and transformed into a science-grade device by Ugo Basile, is one of the oldest used in assessing the effects of a drug on animal behavior. Today it is obviously used in phenotyping and not only in drug screening.

Drugs (e.g. benzodiazepines) or specific phenotypes alter neuromuscular coordination and hence the time that the mouse or rat remains on the rotating rod.

Multiple animals can be tested at the same time and several protocols exist to train and assess the motory coordination through the falling time.

The output results include for each lane:

  • Time elapsed
  • Revolutions
  • Distance
  • Speed
  • Rotating mode

System components and main features

  • The Ugo Basile RotaRod comes complete with:
    • An electronic unit with touch screen to set all parameters and save data
    • USB port to save data and export them in CSV files
    • A PC software to build custom rotation ramps and populate your animal vivarium
  • Additional features include:
    • TTL input/outputs for trip box status and start/stop of the test
    • COM port for maintenance purposes
    • Ethernet port for support and maintenance (to be used at the factory only)



Constant, rocking, accelerating and complex accelerating ramps              

Flexibility for performing virtually all types of motor function and coordination behavioral experiments

Mouse-Rat combination package

The same device cannot be used effectively (think of cleaning) on rats and mice without risk of confounding factors, so a highly discounted package is available for those that buy the two models.

Optional Rod enlarger

It allows to test different animal models and also to vary the test difficulty without acting on the speed or mode

Optional Complex Wheels Thanks to the irregular rung and adjustable pattern, the test gains in complexity and sensitivity

Speed adjustable from 3 to 80 RPMs and multiple modes (constant, rocking, accelerating, complex accelerating ramps)

Allows for a very broad range of animal models and experimental settings

Control unit and USB key saving

No need to connect a PC

Automatic conversion of data into CSV files for the USB stick Possibility to open files in Excel
PC software Possibility to populate your vivarium of animals and to build complex temperature ramps

The RotaRod test is commonly used in combination with other motor tests, such as grip strength and hanging test to measure, motor function, coordination and balance.

The test starts with a training trial with the animals placed on the rod rotating at the lowest speed.  A time threshold (e.g. 1 minute) is set, below which the animal is immediately put back on the RotaRod until it stays on the rod for the threshold time.

After training, the real trials start and the latency to fall as well as the other parameters (see above) are recorded.

The classic test was run at constant speed, but already in the ‘60s (Jones and Roberts, 1968), the advantages of using accelerating modes were shown, such as training reduction, increased sensitivity and statistical significance improvement.

The test is used to test motor deficits in the most common animal models of Parkinson’s, ALS, Huntington’s disease, multiple sclerosis, brain injury and all models where motor coordination and function is to be investigated.
