Title Effects of neutral posture on muscle tension during computer use
Bibliographic information 2001, Vol.7, No.1, p.61-78. Illus. 21 ref.
Abstract The objective of this study was to develop a new approach for evaluating seated work positions. 67 office workers who use a Visual Display Terminal (VDT) during a major portion of their working day were evaluated. Muscle tension was measured by surface electromyography (sEMG) while participants were asked to adopt four selected working postures. Pain was measured before and after ergonomic intervention on the Nordic scale, which was modified for this study. Adjustable workstations were used to place participants in desired positions during the testing sessions and the extended intervention period. Results indicate that this ergonomic intervention may have positive effects on muscle tension and pain, significant enough to encourage employers to implement training and workstation modifications following these guidelines.
