Rota Rod

Rota Rod allows you to study motor coordination using the natural fear of falling response with reliability and accuracy.

SDI’s ROTOR-ROD™ System exploits the natural fear of falling response to help you study motor coordination. To be sure other stimuli don’t interfere with your results, SDI’s rotarod test offers a greater range of falling heights and strategically placed photobeams to avoid false falls, unlike other systems.

Available in three sizes to accommodate mice, rats, or both, this rotarod test also gives you the option to predefine all study sessions in advance —saving time and providing maximum accuracy.

Features

  • Study motor coordination using the natural fear of falling motivation
  • Choose from three rota rod models to fit rats and/or mice
  • Eliminate run time data entry mistakes by defining entire study in advance
  • Expand your rota rod test capabilities with programmable acceleration, constant speed and deceleration-no fixed acceleration
  • Adjust subject falling heights as your study dictates
     

ROTOR-ROD™ is the only rotarod test on the market that uses the natural fear of falling motivation to measure and record motor coordination in both rats and mice. Choose from three different rotarod models, which all include four animal lanes. Use the full-size rota rod apparatus to measure rats, the bench top model to measure mice or a combination unit for rats and mice.

SDI’s rota rod software allows you define your complete study in advance, eliminating run time data entry mistakes that could affect the accuracy of your results. The software also provides you with the ability to program acceleration, constant speed and deceleration steps—giving greater flexibility than rota rod units with fixed acceleration only rod speed ramp profiles.

Compared to other rotarod systems, only SDI’s rotarod test offers adjustable falling heights up to 48 inches, producing true fear of falling motivation. In addition, photobeams placed below the running rod in each lane assure accurate timings by monitoring each animal’s latency-to-fall separately and simultaneously.

SDI’s Rota Rod System highlights:

Reliable Latency Times Ensured with a Natural Stimulus

The use of fear of falling motivation provides a natural stimulus—assuring more reliable latency times. By relying solely on fear of falling to motivate the animals to remain on the running rod, you won’t need to worry about any interfering stimuli on the rotarod apparatus. For the rotarod mice apparatus, the falling height is set to be 18” and for rats, it is adjustable up to 48”.

Run Up to Four Animals Simultaneously yet Independently

Run up to four animals at once for greater flexibility in using the SDI rota rod test. To test simultaneously, simply place one to four animals at a time in individual runs in the enclosure. When all photobeams have been broken, the rod will automatically stop rotating. You can also program a maximum test time to stop the rod, even if all animals have not fallen./p>

No False Falls

Seven photobeams per lane placed strategically below the running rod assure only true falls are recorded. When the animal falls from the rotor rod treadmill, the photobeams record the animal’s latency to fall and distance traveled.  If the animal hangs on and moves around the rod, no fall will be recorded--unlike some other systems.

Prevent Animal Escape

Collect animals after completed tests with ease. The rota rod animal compartments are completely enclosed to prevent animals from escaping after falling from the rod.

Rotor Rod Software

Obtain the greatest level of flexibility and accuracy using the ROTOR-ROD software. Start with defining your complete study in advance by pre-assigning specific animals to specific lanes for each test session, and also by assigning a predefined Ramp Profile to each test session. The software will automatically record your session data and store it in a single study file to make sure all your data are found in one place. When you are ready, display your data right on your computer monitor or export with one click to Microsoft® Excel or to a delimited file type(TAB, CSV, etc.).

  • Ensure Accurate Session Results with Saved Ramp Profiles

    Construct any desired Ramp Profile for rotarod speed using acceleration, constant speed and deceleration steps in any order. Then to save time and ensure accurate duplication of scenarios, save your Ramp Profile for reuse in any rotarod test session.

  • Define Your Study in Advance

    Make sure you collect the most accurate data possible by defining each of your planned test sessions. You will be able to plan session parameters, set subject identifiers, assign subjects to specific test stations, and specify subject parameters such as dose level. To keep from losing any critical data, it will all be stored in a single file format.

  • Automatically Run Sessions

    Defining your study in advance not only saves you time by automating sessions, but eliminates run time decisions and data entry that can cause mistakes. You’ll also ensure your results are tightly coupled to your predefined subject identifiers. Simply follow the ROTOR-ROD™ software instructions to execute the test session.

  • Export Directly to Microsoft® Excel (or any delimited file type)

    The ROTOR-ROD™ software makes table formatted results available for direct export to Microsoft® Excel or to a delimited file type(TAB, CSV, etc.) and automatically identifies data by column headers. Since the data is exported from a single file, you won’t lose critical information and you’ll save time by removing the need to aggregate multiple single files and possibly reformat them again.
