The geotaxis test is employed to assess motor coordination and vestibular sensitivity in rodents. During this test, the rodent is placed on an inclined grid with its head facing downward. This setup allows the rodent to grip the surface and attempt to reorient itself to a head-up position. MazeEngineers offers both acrylic and stainless steel grids for this purpose, with steeper inclines presenting a greater challenge for reorientation, while shallower angles make it easier.
The test is scored based on three criteria: successful reorientation to an upward position within 60 seconds, failure to reorient within the time limit, and attempts to reorient that ultimately fail within 60 seconds.
In addition to the geotaxis test, various other apparatuses are used to evaluate rodent motor function. These include the Grip Strength test, Balance Beam, Parallel Bars, Catalepsy Bar test, Static Rods Test, Gait Test, Parallel Rod test, and Pole test.

The geotaxis test is used to investigate motor coordination and vestibular sensitivity in rodents. The rodent is usually placed in an inclined grid in the head downwards position. The grid allows for grip and allows for the rodent to reorient itself towards an upwards position. The larger angle creates a more difficult barrier toward reorientation. Shallower angles allow for easier geotaxis.
Scoring is done with three categories: measuring the ability to turn upwards within 60 seconds, failure to turn within 60 seconds, and attempted but failed to turn within 60 seconds.
