The Gait module – for research and clinical use
The Gait module includes everything that you need to perform gait analysis with a Qualisys motion capture system. The Gait module is suited for research, education or in a clinical environment.
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.
The Gait module comes with comprehensive documentation and marker set guides so that you can get started quickly.
Choosing the right motion capture solution for your gait lab
If you are measuring patients for the purpose of diagnosis, treatment assessments, or monitoring, the Qualisys Clinical System is the right choice. If you are a research user, the Gait module is best suited.
Measuring on patients? Benefit from the Qualisys Clinical System
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 Clinical Gait Module sheet (page 4). The Qualisys Clinical System 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 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
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
Force plates determine the centre of pressure and force components, enabling advanced biomechanics software such as Visual3D to calculate joint moments and power.
For the research Gait module, any force plate that is compatible with our QTM software may be used. This includes AMTI, Bertec and Kistler force plates and selected instrumented treadmills. For the Qualisys Clinical System, only selected force plates may be used that are medical devices themselves.
Video
Video is used in most gait labs to visualise force vectors (video overlay) and to compare the measured data with the subjective impression from the video. Our Miqus Video cameras are fully synchronized and calibrated with the Motion Capture system, enabling a flawless 3D overlay.
EMG
EMG systems accurately measure muscle activity throughout the gait cycle. With our data collection software Qualisys Track manager, EMG data is recorded synchronously with the motion capture data and into a single file. More information about our digital EMG integrations can be found here.
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.

Class 1m Medical Device
Qualisys Clinical System is a Class 1m Medical Device and ensures regulatory compliance for your whole system.
Biomechanics using Visual3D
Visual3D is tightly integrated with the automation framework in QTM. It provides an extensive biomechanical toolbox and is used in almost all of our analysis modules.
Analysis – No black box
If you are using one of our Analysis Modules, all you need to do is a single mouse click and the Project Automation Frameworks exports data and runs standardised, yet transparent processing.
Alternatively, as a researcher, you can just export the data and write your own analyses with Visual3D or other tools and languages (e.g. MATLAB).
Web reports
With the click of a button, a Word, an interactive offline web report or online web report is populated with the gait analysis results. The report is based on a template prepared by Baker, McGinley and Thomason for a workshop on Impairment focused interpretation at the JEGM meeting, Miami, 2010.
