Force-instrumented treadmills, built in partnership with Lode.
Starting with the fundamentals, the treadmill is engineered for exceptional stiffness and stability, a characteristic of a Lode. Combined with a smooth, and consistent drive system, this ensures accurate and repeatable conditions — critical for reliable gait analysis and running performance testing.
Operation is flexible and user-friendly: the treadmill can be controlled via the integrated front touch display, an optional remote control, or through USB/RS-232 serial communication. It also integrates seamlessly with CPET equipment, making it a versatile solution for both research and clinical environments.
Building on this platform, we offer both 1D (vertical) and 3D (vertical + horizontal) force instrumentation options. The true advantage with the MotionMetrix force treadmill lies in our proprietary vertical force sensor design. It enables a significantly simpler and more cost-efficient system architecture compared to conventional solutions, in both the 1D and 3D case, without compromising performance.
Every model shares the same 1 kHz force sampling and syncs automatically with MotionMetrix G2. Pick the running surface, speed, and force axes your setup needs.

Choose between the 1D (vertical) or 3D (vertical, fore-aft and medio-lateral) force sensing versions. Both integrate seamlessly with the MotionMetrix G2 system but can also be used as standalone for data acquisition synchronized with your existing motion capture system. If you, however, prefer to retain your existing treadmill, it can be fitted with our vertical force sensor and used together with the G2 system.

The minimum software needed for force data acquisition: a Windows-based PC application with real-time visualization of center-of-pressure and force data. Start acquisition manually or via external trigger from a third-party motion capture system.
Our force treadmills integrate seamlessly and synchronously with the MotionMetrix G2 markerless motion capture system, featuring real-time gait feedback and complete 3D gait analysis for walking and running.
