The relationship between the active cervical range of motion and changes in head and neck posture after continuous VDT work.
This study investigated the relationship between the active cervical range of motion (ROM) and changes in the head and neck posture after continuous visual display terminal (VDT) work. Twenty VDT workers were recruited from laboratories. The active cervical ROM of the participants was measured and videotaped to capture the craniocervical and cervicothoracic angles using a single video camera before and after VDT work. Pearson correlation coefficients were used to quantify the linear relationship between active cervical ROM measurements and the changes in the craniocervical and cervicothoracic angles after continuous VDT work. Active neck extension (r=-0.84, p<0.01) was negatively correlated with the mean craniocervical angle, and active neck flexion (r=-0.82, p<0.01) and left lateral flexion (r=-0.67, p<0.01) were negatively correlated with the mean cervicothoracic angle.
