Gait analysis system
CatWalk XT is a complete gait analysis system for quantitative assessment of footfalls and locomotion in rats and mice.
Why use it?
- Quantification of footprints and gait in unforced moving animals
- Accurate and objective data, validated in peer-reviewed research
- Illuminated Footprints: detection of real footprints and body weight distribution
Trusted by researchers around the world
Many CatWalk XT users are currently facing lab closures due to the COVID-19 pandemic. At Noldus IT we strive to make the transfer to your home office as easy as possible, so that you can continue the analysis of your acquired CatWalk XT runs remotely. Besides, we are also giving the opportunity to refresh and/or acquire new knowledge of CatWalk XT free of charge!

Assess gait and locomotion
CatWalk XT is a highly sensitive tool to assess gait and locomotion. The footprints are captured while the rat or mouse voluntarily traverses a glass plate towards a goal box. CatWalk XT visualizes the prints and calculates statistics related to print dimensions and the time and distance relationships between footfalls.
Who uses it?
CatWalk XT gait analysis has been validated in research and experimental procedures for several (neurological) disorders and lesions. Examples include spinal cord injury and other nerve injuries, neuropathic pain, arthritis, stroke, Parkinson’s, Cerebellar ataxia, traumatic brain injury, peripheral nerve damage, and more.

CatWalk XT is a complete tool for automated gait analysis in rodents. The system consists of:
- A walkway that directs the free movement of your subject in a straight line to facilitate learning and improve reproducibility
- Easy access to the walkway which allowes quick cleaning
- A hardened glass walkway that enables CatWalk XT's Illuminated Footprints technology
- A high speed color camera for extremely accurate spatial and temporal resolution
- And the CatWalk XT software for the recording and automated analysis of the locomotor ability of your rodents

Advanced gait analysis
Due to the high temporal and spatial resolution of the color camera in combination with the Illuminated Footprints technology, the CatWalk XT software can identify subtle changes within the dimensions, position and timing of each footprint. Numerous parameters are calculated for qualitative and quantitative analysis of individual footfalls and gait.
- Individual footprints: print area, brake and propulsion phase duration, stand index, Duty cycle, intensity
- Distances between footprints: base of support, stride length, distance between ipsilateral prints
- Time relationships between footprints: cadence, support formulas, step sequence, phase lags, walking speed
CatWalk XT can be used to evaluate any kind of experimental model or procedure that has an effect on the locomotor ability of rodents. It does not matter if gait is affected due to genetic, chemical or physical injury to the central nervous system, peripheral nervous system, or skeletal or muscle functioning. As long as your animal is able to traverse the CatWalk runway, you can evaluate its gait.

Getting the perfect run
CatWalk™ XT is a gait analysis system based on the voluntary movement of rats or mice across a corridor, over a glass plate. Generally, animals quickly learn to cross in a consistent manner, especially rats. However, familiarizing them with the system before you start your experiment makes your job a lot easier. So how do you familiarize and motivate your rats?

How does it work?
The Automatic Footprint Classification Module takes the manual labor of classifying each footprint out of your hands, cutting your experiment time in half, while keeping you in control.
The Interactive Footprints Measurements module allows you to look in more detail at each footprint itself. You can measure toe spread, intermediate toe spread,and print lenght in order to calculate the Sciatic Functional Index. Furthermore, you can use it to measure the angle of the pawprint in relation to the body axis of the rodent.
