When is a rigid pelvis–trunk approximation sufficient? An output-specific model-reduction protocol applied to lumbar mobility in multibody biomechanics

This preprint presents an output-specific computational model-reduction protocol for evaluating when simplified lumbar mobility is sufficient in multibody biomechanics. The primary study compares mass-equivalent exact-lock, axial-yaw-only and three-coordinate lumbar architectures...
