Preclinical GAIT analysis

The CatWalkTM XT system is a highly sensitive tool for quantitative assessment of footfalls and motor performance in unforced moving animals such as rats, mice and guinea pigs.

Catwalk Souris

It can be used to evaluate any experimental model/procedure that affects locomotor ability of rodents (i.e. genetic, chemical, physical injury to the central nervous system, peripheral nervous system or skeletal or muscle functioning). More specifically, its use has been validated for spinal cord injury and other nerve injuries, neuropathic pain, arthritis, stroke, Parkinson’s disease, cerebellar ataxia, traumatic brain injury and peripheral nerve damage.

Motion analysis

We can offer you a fully integrated analysis of the subject including spatio-temporal parameters (step frequency, step length, velocity, single and double support time…) and kinematics parameters (angular range of motion, velocity, ground reaction forces, muscles activity). Tests are performed in a 27 meters long-room (ensuring that subjects reach stabilized gait) in which the equipment can be used simultaneously and be synchronized on demand.

 

Force plates measure the ground reaction forces generated by a body standing on or moving across them, allowing investigators to quantify balance, gait and other biomechanical parameters.

Electromyography (EMG) allows to evaluate muscles activity and is composed of several sensors (one for each studied muscle) placed at the surface of the skin. EMG is mainly used as a diagnostic tool to identify neuromuscular diseases and can be applied to study the effect of a given treatment (drug, rehabilitation program), ergonomics…

The Locometrix® accelerometer device provides a quick and informative walking test in the context of defining a diagnosis. The software automatically calculates 6 common dynamic characteristics of walking: symmetry, regularity, force, frequency, pathogenic shock waves and frontal instability. The system provides reference databases, allowing the user to interpret the test results in a matter of minutes. In practice, an accelerometer, fixed by a belt on the lumbar region, registers all movements of the center of gravity during walking, running or other athletic movements.

Codamotion® is a 3D motion capture system, which tracks and analyzes 3D movement. This system is very versatile and can provide a large variety of information including the common gait parameters (stride frequency, gait velocity…) as well as kinematic information (ankle, knee, hip angles).

A Codamotion® system is ideal for analyzing all scales of human body. Small scales details of hand, face, feet and spine can be captured together with large-scale whole-body movements. Critically the active maker technology used in Codamotion® systems produces real time data. Less than 1ms elapses between a measurement and its availability for processing and display.

With a set of range laser scanners, engineers at ULg have developed a new non-intrusive feet tracker system called GAIMS (for “Gait Analysis Imaging System”, “Gait Measuring System »). The observed person does not need to carry any sensor or marker, has not to wear special clothes, and is not restricted to walk on a small area such as a treadmill.

This system can detect the real time position of each foot during different types of simple walking tasks. It enables the calculation of different gait parameters (global or single foot walking speed, single and double limb support times, base of support width, number of missteps…).

These characteristics can be used for the diagnostic of various diseases and for the longitudinal follow-up of patients with walking impairments.
