Accuracy of spine cumulative loading using self-reported duration and frequency information during non-occupational tasks

Cost effective documentation of cumulative loads in non-occupational tasks may help to explain why low back pain continues to persist in occupational settings despite the modification of peak work exposures that regularly occur in industry. Self-report methods may provide a less time and equipment intensive approach for documenting cumulative exposure and be useful for assessments of industrial tasks with varied time demands that pose significant challenges using traditional video-based approaches.
