Title Back posture and low back muscle activity in female computer workers: A field study
Bibliographic information Feb. 2009, Vol.24, No.2, p.169-175. Illus. 35 ref.
Abstract The aim of this study was to examine the relationship between back posture, low back muscle activity and low back pain among women computer workers. Twenty-one female computer workers participated. Surface electromyographic activity was recorded from several lumbar region muscles throughout the workday. Inclinometer recordings from the pelvis, upper trunk, and left thigh were used to determine back posture. Low back pain intensity was reported using a visual analogue scale every hour throughout the work and leisure periods. Subjects reporting low back pain during the workday were not distinguished by duration of sitting, sitting posture or low back muscle activity. Other findings are discussed.
