Motionprint Ergo - NIOSH Lifting Equation Module: Validation of Body-Position Variable Extraction
Year: 2026
Type: report
Abstract: This report validates the NIOSH Lifting Equation module of Motionprint Ergo — ergonomic assessment software developed by Motionprint BV. The validation examines whether body-position variables and task parameters extracted automatically from Xsens motion capture data (MVNX format) match the values that would be assigned by a trained assessor following the revised NIOSH Lifting Equation methodology (Waters, Putz-Anderson & Garg, 1994). Key variables assessed include horizontal distance, vertical height, asymmetry angle, and frequency multiplier derivation. Results confirm that the automated extraction produces Recommended Weight Limit (RWL) and Lifting Index (LI) scores consistent with manual assessment, supporting the use of Motionprint Ergo for validated NIOSH assessments in occupational health and H&S applications.
