Gait Lab of the Future
GRAIL is a total package solution for gait analysis and gait training. GRAIL empowers user friendly assessments and exercises, in challenging conditions, to improve (pathological) gait patterns. Real-time feedback in GRAIL enable analysis and training during the same session.
Why Choose GRAIL
GRAIL facilitates the analysis and training of impaired walking in patients with neurological and neuromuscular problems, orthopedic patients, and the elderly. The rich, immersive Virtual Reality environments combined with existing scientifically proven clinical protocols offer a faster and better rehabilitation process. All this functionality requires less than 1/3 of the lab space of a traditional gait lab, with a 100% utilization rate because of the extensive training options.
The GRAIL Way
Conventional gait analysis is, although scientifically proven to be effective, time consuming, complex, and expensive, which means that most labs limit their service to a small number of patients.
The GRAIL’s fully instrumented dual-belt treadmill allows you to measure and analyse hundreds of steps in just a few minutes. The treadmill’s self-paced mode enables the patient to initiate gait and walk at a self selected pace, while the treadmill and the VR environment run in perfect synchronization to create a natural optical flow. Because of these unique features patients walking on a GRAIL show a natural variance in gait that is also seen in walking over ground. (Krogt et al, 2014; Gates et al., 2012)
“With the GRAIL clinical gait analysis and gait training in various conditions can be used to obtain faster and better rehabilitation results”

How GRAIL Works
Synchronized VR environments, projected on a semi-cylindrical screen, immerse the patient in virtual worlds and natural walking environments. GRAIL combines a fully instrumented treadmill with a self-paced option, an integrated motion capture system, 3 video cameras, and an EMG system. All the components are integrated and synchronized via the D-Flow software making the information available in real-time for the calculation of all gait parameters. Simulate walking uphill & downhill, combined with visual stimuli, to challenge patients while measuring gait behavior to perform a ‘functional gait analysis’.
Functional Gait Analysis
The GRAIL’s unique combination of real-time data processing, treadmill perturbations and virtual reality allows you to challenge the patient with mechanical, visual and cognitive dual-tasks in a safe, controlled environment. Measuring the changes in gait pattern during these situations allows for the identification and quantification of pathology specific compensation strategies or determining the dynamic stability. Once the gait analysis is completed, a training session can be initiated to improve the impaired gait functionality right away.
“If you really want to improve your walking, GRAIL is the best tool you can have because it combines all therapies in a functional, challenging environment.”

Check out how the GRAIL is used by our clients.
The GRAIL is used by a wide range of users, in the playlist you can find a selection of videos with the practical application of the GRAIL.
The Gait Offline Analysis Tool (GOAT) offers intuitive data analysis and facilitates communication with the (medical) specialist as well as between the specialist and the patient. It presents the GRAIL’s synchronized video data, motion capture data, ground reaction forces and an interactive set of customizable graphs. The recording of multiple steps makes it possible to calculate averages, standard deviations and variations of gait parameters over time. The GOAT can produce a complete gait report in only a few minutes so the data can be analyzed directly after the session.
