The Problem: Posture ≠ Injury Risk
Workplace musculoskeletal disorders (MSDs), particularly low-back injuries, cost the U.S. economy billions annually.
Most current ergonomic tools:
Detect non-neutral posture
Count repetitions
Use observational scoring methods
Provide generalized risk reports
But injury risk is not caused by posture alone.
It is caused by mechanical loading on the spine over time.
This allows us to compute a user-specific cumulative risk score based on mechanical loading, not just posture deviation.
Our Scientific Foundation: Biomechanics + Physics-Based Modeling
ErgonSense is grounded in established biomechanical principles of spinal loading and occupational ergonomics.
We combine:
Trunk kinematics (IMU-based posture sensing)
Load distribution data (pressure insoles)
Physics-based modeling
Machine learning classification
Laboratory data collection setup integrating Xsens IMU-based motion capture and Noraxon electromyography (EMG) to validate biomechanical modeling and risk prediction algorithms.
