Accelerating rotarod

The rotarod is designed to test balance and motor coordination. Animals are placed onto a horizontal rotating rod which accelerates over the course of a trial. A single trial lasts from the time the animal is placed on the rod until it falls off or until 5 minutes have elapsed. Animals can also be tested chronically to examine learning or motor degeneration.

Grip Strength

The grip strength assay uses a meter to measure forepaw strength based on force exerted to pull back a metal grid.

Horizontal ladder

The horizontal ladder measures motor coordination and gait by observing foot placement as the rat walks across the ladder.

MotoRater Assay

This is a semi-automated system for rodent kinematic gait analysis with high sensitivity to evaluate 4 different motion modalities – over ground walking, skilled ladder walking, wading in water and swimming.

Contact Heather Mitchell with questions.

Hot Plate

The hot plate assay measures thermal sensitivity by recording the latency to the first aversive response.
