FlexiGait provides AI-powered, markerless 3D gait measurement from single-camera RGB video, delivering lab-grade insights without markers, wearable sensors or a dedicated motion-capture laboratory.
FlexiTrace Posture Analysis measures body alignment from a single image, screens for four common postural patterns and generates a corrective exercise plan.
FlexiGait was compared against a Vicon marker-based motion capture reference in 31 healthy adults from the public GPJATK dataset.
Agreement was moderate for swing phase (ICC = 0.72). These results were obtained in healthy adults recorded in a laboratory setting; performance has not been established in any patient population.
The study was carried out with Prof. Ali Kiapour and Prof. Santiago A. Lozano Calderon. Results were presented at the GAMMA Congress 2025, ESMAC 2025 and the ORS 2026 Annual Meeting.
