||A randomized controlled trial of chair interventions on back and hip pain among sewing machine operators: The Los Angeles garment study
||Mar. 2008, Vol.50, No.3, p.255-262. Illus. 15 ref.
||The objective of this study was to determine whether a height-adjustable chair with a swivel function can reduce back and hip pain in sewing machine operators. This four-month intervention study included 293 sewing machine operators with back and hip pain, divided into two intervention groups and a control group. Participants in the control group received a placebo intervention (miscellaneous items), and participants in the intervention groups received the placebo intervention and one of the two types of intervention chairs (with flat or curved seat pan). Compared with the control group, mean pain improvement for the flat chair was 0.43 points per month and mean pain improvement for the curved chair was 0.25 points per month. The findings may also be relevant in other manufacturing jobs.
