Detecting ACL-Deficient Kinematics In Vivo · with Rush University Medical Center
January 2026
First labeled in-vivo dataset of ACL failure biomechanics on living humans. ACL-deficient knees exhibit 22% greater rotational displacement and 58% faster rotational rate than healthy controls. Model accuracy 93–99% distinguishing ACL-deficient from healthy kinematics on individualized profiles; 75% precision localizing the injury window within a movement sequence from raw sensor data alone.

Rotational Restraint Under Controlled Cadaveric Load · with Cleveland Clinic
September 2025
Robotic ex-vivo quantification on Cleveland Clinic's simVITRO bio-robotics platform. 10–25% reduction in tibial rotation under constant torque across flexion angles, with angle-dependent protection increasing at flexion. No coupling into adjacent kinematic axes.
Cross-Task Kinematic Generalization · with Edge Hill University / UK Athletics
2025
Multi-task biomechanical capture across change-of-direction, drop landings, deceleration, and gait. 10-camera Qualisys motion capture and dual Kistler force plates at 2,000Hz. Intervention halted knee flexion in 11 of 11 activations without compensatory loading at hip, ankle, or trunk in 55% of trials.
Longitudinal In-the-Wild Biomechanical Capture · with SPIRE Academy
2025
50+ hours of continuous high-intensity biomechanical data across 15 elite athletes: sprinting, cutting, jumping, contact scrimmage. First longitudinal in-the-wild dataset of its kind. Zero skin irritation, overheating, or measurable performance impairment.
Real-Time Valgus Detection from On-Body Sensing · with UK Athletics
2024–2025
On-body sensor signal validated against laboratory motion capture during single-leg jump-landing. 68% reduction in valgus angle achieved on threshold-triggered intervention in the live training environment, with no external equipment.
Valgus Reduction in Single-Leg Landing · Hippos internal study
Summer 2025
Live-subject quantification of active intervention across 17 athletes and three intervention designs in the dominant ACL injury scenario. Peak valgus angle change reduced from 6.1° to 1.95°. Engagement within the ~60ms injury window. Faster than neuromuscular reflex.
Sub-30ms Closed-Loop Intervention Latency · Hippos internal study
2024
Closed-loop benchmarking on anatomically-accurate synthetic knees (3D-printed bone + ballistic gel, ~90% human fidelity). 6,400Hz on-device sensing; mean deployment 30ms; 0.15% false positive rate across 54 live cartridge deployments and 4,000 computational simulations.
