Title Effectiveness of a new back belt in the maintenance of lumbar lordosis while sitting: A pilot study
Bibliographic information Oct. 2003, Vol.32, No.4, p.299-303. Illus. 10 ref.
Abstract With the expanding use of video display terminals, a high incidence of low back pain is reported among operators working at screens in sitting postures. This study describes a new design of back belt for use by operators working at screens in seated postures and compares the conditions of wearing this belt with those of no belt wearing. Nine subjects performed a data entry task while sitting at a desk during 60-min periods, during which the trunk and lumbosacral angles were observed. Results showed that there were significant differences in trunk angle and lumbar posture when wearing or not wearing the belt (with an average difference of -14.1░ in lumbar lordosis and 16.9░ in trunk angle) during the final 10-min stage of the task. The belt seemed to provide support for the back by the counter-supporting force from the knees. The results suggest that the belt may be useful in seated tasks because of its maintenance of lumbar lordosis and erect trunk.
