The correlation of duration of cervical flexion per day with neck disability index scores in office workers: a cross sectional study

Abstract Background: An increasing number of office workers complain of neck pain after extended smart phone use. We conducted this study to examine the correlation between the duration of cervical flexion per day (DCF) during smart phone use and neck disability index scores (NDI ) scores of office workers in China.Methods: In this cohort study, 1791 individuals responded to an on line questionnaire. For our study, we included responses of 498 [27.8%] office workers. Excluded from the study were 1293 [72.9%] individuals including building workers, students, non-office workers, and those who did not complete the questionnaire. Participants completed an online questionnaire survey from May 29, 2019 to April 10, 2020. The NDI was used to evaluate cervical symptoms. Multivariable logistic regression, threshold saturation effect analysis, t-test, and Pearson’s chi-square tests were used to analyze the data. Results: We analyzed questionnaire results of the 498 office workers. The t-test showed no significant differences among the gender groups for age, working age, and NDI scores (P>0.05). Compared with other activities, smart phone use had no positive correlation with NDI scores (P>0.05), while low back pain had a strong correlation with NDI scores (P<0.05). When adjusting for age, working age, and low back pain covariates, DCF had a positive correlation with NDI scores. In addition, DCF had a curve line correlation with NDI-a monotone increasing relationship; the fold point was 6 (P<0.05).Conclusions: DCF had a positive curve line correlation with the NDI suggesting that office workers should limit DCF to a maximum of 6 hours to decrease NDI scores.

Abstract Background Physical activity (PA) is essential in the management and rehabilitation of low back pain (LBP). However, it is not clear if workplace PA interventions can improve LBP. This study aimed to investigate the effects of workplace interview intervention on increasing PA and improving LBP among office workers. Methods We recruited 37 workers of a manufacturing company in Aichi, Japan. Participants were randomly assigned to the intervention group (n=20) or control group (n=17). We affixed waist-worn accelerometers to monitor PA in all participants, and provided face-to-face counseling with a physical therapist or nurse once a week for 12 weeks as workplace PA program to reassurance and encourage participants to keep high levels of PA. PA and LBP severity were assessed at baseline, 3 and 6 months. Results Baseline characteristics were similar in both groups, but PA was significantly higher in the intervention group than in the control group at 3 and 6 months. In the intervention group, was PA significantly increased at 3 and 6 months from baseline and LBP severity improved significantly at 6 months from baseline. We calculated the effect size of the interview intervention, and found that workplace interview intervention had a medium to large effect on PA and LBP severity. Conclusions Our data suggests that workplace PA intervention can increase PA and improve LBP among office workers.
