Title Are neck flexion, neck rotation, and sitting at work risk factors for neck pain? Results of a prospective cohort study
Bibliographic information Mar. 2001, Vol.58, No.3, p.200-207. 24 ref.
Abstract To study the relation between neck pain and work-related neck flexion, neck rotation and sitting, a prospective cohort study was performed with a follow-up of 3 years among 1,334 workers from 34 companies. Work-related physical load was assessed by analysing objectively measured exposure data (video recordings) of neck flexion, neck rotation and sitting posture. Neck pain was assessed by a questionnaire. Adjustments were made for various non-occupational physical factors, psychosocial factors and individual characteristics. A significant positive relation was found between the percentage of the working time in a sitting position and neck pain, with an increased risk of neck pain for workers sitting more than 95% of the time (crude relative risk (RR) 2.01; adjusted RR 2.34). A positive relationhip between neck flexion and neck pain was found, suggesting an increased risk for people working with the neck at a minimum of 20░ of flexion for more than 70% of the time (crude RR 2.01; adjusted RR 1.63). No clear relationship was found between neck rotation and neck pain.
