ارتباط کار با کامپیوتر با ایجاد وضعیت سر به جلو آمده و گردن درد در بین جامعه کارکنان اداری

Background and aim:Neck pain (NP) is among the common musculoskeletal problems which may be caused or developed due to holding an inappropriate position of head and neck while working. The aim of present study was to investigate if work with computer relates with the forward head posture and its relationship with the neck pain among the office workers Material and Methods: A cross-sectional study in 2011-12, included 165 office workers of Semnan Welfare organization who were randomly selected. No limitation such as age, occupation and … were considered and all voluntaries with more than one year work experience could enter.After completing the questionnaires and existance of NP, considering its high incidence among women and to decline the gender confounding effect, 60 women were paired in two groups: with versus without NP. The head angle in compare to nack (CV angle) was measured using the goniometer. A Statistical software was used to analyze the data. Chi-square, mann-withney and independent t test were used for analyses. Results: The results regarding evaluation of instruments’ reliability were acceptable (the questionnare and CV angle measurement, Intera-class Correlation Coefficient 0.872 and 0.89, consequently). The CV angle of the neck pain group was significantly smaller than that in the control group(P<0.001). The relationship between more than three ours work with computer and forward head posture was also significant (P=0.01). Forward head posture among those who worked with computer more than 3 hours a day was 5.52 more common in compare to those who used computer maximum 3 hours a day. Discussion and Conclusion: Office workers who worked with computer more than three hours in compare to the opposite group, showed less Cranio-Vertebral (CV) angle. It could increase the risk of developing Forward Head posture. The CV angle of the neck pain group was significantly smaller than that in the normal group.A reverse relationship was found between the existance of neck pain and CVangle participants with NP showed less CVangle. Additionally, this study confirmed CVangle measurment as a reliable measuremant method to evaluate head and neck position. CV angle measurement with goniometer showed a reliable method to assess the posture of head and neck.
