||A novel approach for evaluating level, frequency and duration of lumbar posture simultaneously during work
||Dec. 2001, Vol.27, No.6, p.373-380. Illus. 17 ref.
||In this study, statistical models are proposed for determining the essential characteristics of postural loads. A direct registration of lumbar posture was made over a workday with an inclinometer for 64 nurses, 16 housekeepers and 27 office workers. An exposure variation analysis was used to summarize information on the angle of trunk flexion, the time period of maintained postures, and the percentage of work time. A hierarchical regression analysis was used to compare these characteristics. The occupational groups did not differ in either frequency or duration of trunk flexion >30░. Nurses were exposed to longer work times than the office workers with trunk flexions of 30-70░ maintained for less than five seconds, whereas office workers experienced longer work times at angles of <30░ for longer periods. Comparable differences were found between housekeepers and office workers. This method offers an alternative to conventional ergonomic analysis in which the dynamics of exposure are often ignored.
