Gait analysis for research and clinical use
Qualisys offers motion capture solutions for gait analysis tailored for both research and clinical use. When selecting a motion capture solution for your gait lab, consider the specific needs of your application – whether clinical or research-oriented – to make the appropriate choice between the two offerings.
- The Qualisys Clinical System (QCS) for gait analysis is recommended for tasks such as diagnosis, treatment assessments, or patient monitoring.
- On the other hand, the Gait Analysis module is more suitable for research users.
Our Gait Analysis modules include everything that you need to perform gait analysis with a Qualisys motion capture system. By being able to select from a wide range of marker sets, event modes, hardware devices and capture modes, we ensure that our software adapts to your protocols. Each module comes with comprehensive documentation and marker set guides so that you can get started quickly.

Benefit from the Qualisys Clinical System for gait analysis
The Qualisys Clinical System (QCS) is a subset of our hardware and software that has been specifically approved to be used as a medial device. Don’t worry – this subset is broad enough to find the right combination that fits your needs.
A detailed list of compatible devices can be found in the Qualisys Clinical System brochure on page 4. The QCS is a medical device with European Class 1m CE marking and has been cleared by the FDA for clinical use in the U.S.
Research project?
Benefit from unprecedented flexibility
Select the Gait Analysis Module for research to get a solution that integrates seamlessly with many other systems, including force plates, EMG and eye-trackers, offering endless possibilities for your projects. You can always export via c3d, text or MATLAB files for further analysis.
Gait marker sets
We understand that there is not a single marker set that fits the specific needs and preferences of all gait labs. That is why the Gait Module supports different marker sets, all of which have a proven record of being used in well-established gait labs. Take a look here for more details on supported marker sets.

Motion capture cameras for gait analysis
With our range of motion capture cameras, you can be sure to find the right fit for your room size and needs (e.g. small markers in multi-segment foot models). Our experts will assist you to find the best camera setup and mounting options to ensure data of the highest quality.
Force plates, EMG & other external hardware
Our Gait Analysis modules work with a range of major force plates and EMG systems. Compatible external equipment becomes a part of a single Medical Device that you can safely use in a clinical environment. For use in a clinical system, a detailed list of compatible devices can be found in the Qualisys Clinical System brochure on page 4.

Synchronized Video for Gait Analysis
The Miqus Video Plus calibrates and synchronizes with our Qualisys motion capture cameras, delivering exceptional 3D overlays with a full resolution of 2.8MP. Video capture is extensively utilized in gait labs to visualize force vectors via overlay and to correlate the measured data with subjective video impressions.
Go markerless
The Gait analysis module offers the option to use markerless capture – all within a single, streamlined workflow, no matter if you are testing with or without markers.
