Comparative evaluation of exoskeleton performance for bending, squatting and lean forward tasks: A case study of passive trunk exoskeleton
SessionPoster Session 2
DescriptionThis study evaluated the performance of a passive trunk exoskeleton in reducing lumbar spine (L5/S1) joint loads during bending, squatting, and forward-leaning tasks. Ten adult male participants performed these tasks with and without exoskeleton support, while motion capture and force plate data were analyzed using biomechanical modeling. The results showed a significant reduction in compressive load and subject moment at the L5/S1 joint with exoskeleton use, with the extent of load reduction proportional to trunk flexion angle. The greatest benefit was observed during full bending (27.1% reduction), followed by squatting (18.3% reduction) and forward-leaning (13.2% reduction) tasks, while the least effect occurred during standing. These findings confirm that passive trunk exoskeletons provide substantial support across various occupational tasks, particularly for those involving greater trunk flexion, and can inform task-specific implementation.
