Biomechanics

Motion capture technology has become essential to modern biomechanics, providing precise, real-time 3D tracking to study human movement, improve diagnostics, and enhance research outcomes across sports science, rehabilitation, and medical research. On the hardware side, our OptiTrack systems deliver industry-leading optical tracking for gait analysis and athlete performance monitoring, Polhemus electromagnetic trackers offer embeddable, line-of-sight-free sensing for constrained or clinical environments, Noitom's Perception Neuron systems bring camera-free inertial tracking to any space, and StretchSense gloves add high-fidelity hand and finger biomechanics data for research into grip and fine motor movement. To turn that raw tracking data into meaningful biomechanical insight, we also stock THEIA, HasMotion, and STT Systems software. THEIA (Theia3D) is an AI-driven markerless motion capture platform, letting researchers track 124 keypoints for precise 3D skeletal models without markers or lab-only setups, making it well suited to sports performance, gait research, and real-world clinical environments. HasMotion's Visual3D toolkit processes data from marker-based and markerless motion capture systems, inertial sensors, force platforms, and EMG recordings, turning any mocap feed into detailed joint forces and muscle moments for custom biomechanical models. STT Systems rounds out the software range with 3D motion analysis tools built specifically for sport scientists, clinicians, and researchers, combining kinematic and kinetic analysis with third-party systems like Delsys EMG for a full picture of neuromuscular performance and musculoskeletal health. Whether you need markerless AI-driven capture, a flexible modelling toolkit, or a complete sports biomechanics platform, our hardware and software range gives researchers, clinicians, and coaches the tools to go from raw movement to actionable insight.
