Effects of Visual Display Terminal Works on Cervical Movement Pattern in Patients with Neck Pain

[Purpose] This study examined changes in the onset of neck movement in young adults with and without mild neck pain (MNP) during visual display terminal (VDT) work. [Subjects] Ten control subjects and 10 subjects with MNP who were VDT workers were recruited. The upper (UC) and lower cervical (LC) spine angles in the sagittal plane were collected using an ultrasound-based motion analysis system during VDT work for 5 min. [Results] The MNP group had faster movement initiation in the UC and LC compared with the control group during VDT work. [Conclusion] These findings suggest that young adults with MNP should be cautious when performing VDT work while sitting.
