摘要

This 4 month randomized controlled trail evaluated the effect of chair design on neck/shoulderpain among sewing machine operators. 277 sewing machine operators with neck/shoulder painwere assigned to receive (1) miscellaneous items (control group), (2) a chair with a flat seat panplus miscellaneous items, or (3) a chair with a curved seat pan plus miscellaneous items.Participants who received the flat seat chair experienced a decline in pain of 0.14 (95% CI: 0.07to 0.22) points per month compared to those in the control group, while those who received thecurved seat experienced a decline of 0.34 (95% CI: 0.28 to 0.41) points per month compared tothose in the control group. These findings demonstrate that an adjustable height task chair with acurved seat pan can reduce neck and shoulder pain severity among sewing machine operators.
