Improved neck posture and reduced neck muscle activity when using a novel camera based workstation for manual precision inspection tasks.

Abstract Purpose This study investigates the effects of the usage of a novel camera system compared to a conventional lens system for manual precision tasks. Utilizing the novel camera system aims to improve neck posture, reduce neck muscle tension and thereby minimize the risk of neck pain. Methods Camera and lens systems were compared by assessing the craniovertebral angle (CVA), electromyographic activity of the M.trapezius and perceived exertion. 16 healthy participants (n = 8 female, 24 ± 2 years; n = 8 male, 30 ± 5 years) performed manual precision tasks in a cross-over design using both systems in sitting and standing positions. Results Analyses showed that using the camera system improved the CVA in sitting [28.4° (22.8°–33.9°) to 42.5° (38.9°–46.1°); p  Conclusions The camera system may prevent neck pain in workers performing manual precision tasks in sitting and standing postures.
