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 time of cervical flexion (CFI) during smart phone use and cervical symptoms 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 (Neck Disability Index) 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, CFI had a positive correlation with NDI scores. In addition, CFI had a curve line correlation with NDI-a monotone increasing relationship; the fold point was 6 (P<0.05).Conclusions: CFI had a positive curve line correlation with the NDI suggesting that office workers should limit CFI to a maximum of 6 hours to decrease cervical symptoms.

Background Few data are available on the course of and predictors for disability in patients with chronic nonspecific low back pain (CNSLBP). Objective The purpose of this study was to describe the course of disability and identify clinically important prognostic factors of low-back-pain–specific disability in patients with CNSLBP receiving multidisciplinary therapy. Design A prospective cohort study was conducted. Methods A total of 1,760 patients with CNSLBP who received multidisciplinary therapy were evaluated for their course of disability and prognostic factors at baseline and at 2-, 5-, and 12-month follow-ups. Recovery was defined as 30% reduction in low back pain–specific disability at follow-up compared with baseline and as absolute recovery if the score on the Quebec Back Pain Disability Scale (QBPDS) was ≤20 points at follow-up. Potential prognostic factors were identified using multivariable logistic regression analysis. Results Mean patient-reported disability scores on the QBPDS ranged from 51.7 (SD=15.6) at baseline to 31.7 (SD=15.2), 31.1 (SD=18.2), and 29.1 (SD=20.0) at 2, 5, and 12 months, respectively. The prognostic factors identified for recovery at 5 and 12 months were younger age and high scores on disability and on the 36-Item Short-Form Health Survey (SF-36) (Physical and Mental Component Summaries) at baseline. In addition, at 5-month follow-up, a shorter duration of complaints was a positive predictor, and having no comorbidity and less pain at baseline were additional predictors at 12-month follow-up. Limitations Missing values at 5- and 12-month follow-ups were 11.1% and 45.2%, respectively. Conclusion After multidisciplinary treatment, the course of disability in patients with CNSLBP continued to decline over a 12-month period. At 5- and 12-month follow-ups, prognostic factors were identified for a clinically relevant decrease in disability scores on the QBPDS.
