What is the GA.I.T Analysis System?

A table-top gait system for mice. The mouse walks freely along a glass corridor between two side cages. A GoPro Hero13 Black films the run through a 45° mirror, so the ventral view of the paws and the lateral view of the body land in the same frame.

Paws, digits and body parts are identified by supervised AI. Valid runs are picked automatically during the session, and results export to CSV or Excel. Ugo Basile states that no manual paw correction is needed. In most footprint systems, manual paw correction is where the analysis hours go.

Key Features

• AI identification of paws, digits and body parts, down to single-digit resolution
• Simultaneous ventral and lateral imaging through a 45° mirror
• Green LED frustrated total internal reflection (fTIR) lighting plus red light
• Automatic session mode that keeps valid runs only
• Integrated GoPro Hero13 Black camera
• Pre-configured AI PC with the software installed
• 69 × 56.5 cm on the bench

What it measures

Spatial: paw print intensity and geometry, stride length, paw angle, toe spreading, step width, length and height between paw pairs, Sciatic Functional Index, body and tail area.

Temporal: number of steps, stance, braking and propulsion times, step cycle, duty cycle, stride time, cadence, speed variation, inter-paw intensity cross-correlation.

Mixed: velocity, body direction angle, tail laterality and tail flexibility. Some parameters are still listed by Ugo Basile as available soon. Check which ones before building an endpoint around them.

Mice only

The corridor is 5.5 cm wide and the side cages are 12 × 8 × 8 cm. This is a mouse system. A rat study needs a different instrument.
