Biomechanical risk factors for occupationally related low back disorders.
A continuing challenge for ergonomists has been to determine quantitatively the types of trunk motion and how much trunk motion contributes to the risk of occupationally-related low back disorder (LBD).
It has been difficult to include this motion information in workplace assessments since the speed at which trunk motion becomes dangerous has not been determined.
An in viva study was performed to assess the contribution of three-dimensional dynamic trunk motions to the risk of LBD during occupational lifting in industry.
Over 400 industrial lifting jobs were studied in 48 varied industries.
The medical records in these industries were examined so that specific jobs historically categorized as either low, medium, or high risk for occupationally-related LBD could be identified.
A tri-axial electrogoniometer was worn by workers and documented the three-dimensionalangular position, velocity, and acceleration characteristics of the lumbar spine while workers worked at these low, medium, or high risk jobs.
Workplace and individual characteristics were also documented for each of the repetitive lifting tasks.
A multiple logistic regression model indicated that a combination of five trunk motion and workplace factors predicted well both medium risk and high risk occupational-related LBD.
