简要总结
Cervicogenic headache (CgH) is a distinct form of headache and accounts for 17.8% of all headaches and the prevalence rate is between 0.4% and 20%. A guide to health and safety in the office handbook by common wealth of Australia (2008) suggested the ergonomic guidance and interventions for preventing and treating musculoskeletal disorder (MSD) injuries in the office workers. Also, It has been estimated that 34% of US citizens receive some sort of physiotherapy for CgH each year. However, no studies have compared and investigated the combined and individual effects of workstation ergonomics, physiotherapy and patient education for improving cervicogenic headache and work ability in office workers.

Cervicogenic headache (CgH) is a distinct form of headache and accounts for 17.8% of all headaches and the prevalence rate is between 0.4% and 20%. A guide to health and safety in the office handbook by common wealth of Australia (2008) suggested the ergonomic guidance and interventions for preventing and treating musculoskeletal disorder (MSD) injuries in the office workers. Also, It has been estimated that 34% of US citizens receive some sort of physiotherapy for CgH each year. However, no studies have compared and investigated the combined and individual effects of workstation ergonomics, physiotherapy and patient education for improving cervicogenic headache and work ability in office workers.
Therefore, our study objective was intended to compare and investigate the combined and individual effects of workstation ergonomics, physiotherapy and patient education in improving cervicogenic headache and work ability in office workers. This randomized clinical trial hypothesized that there is a difference in primary and secondary outcome measures between workstation ergonomics, physiotherapy and patient education for improving cervicogenic headache and work ability in office workers.

盲法说明
Because of the experimental nature of the study methodology, it was not feasible to blind the treating therapist as well as the participants included in the study. The therapists who assessed the outcome variables at baseline, 4-weeks, 8-weeks, and 6-months were blinded. Therefore, the therapist providing the treatment and the therapist measuring the data were different individuals. In addition, the outcome-measuring therapist continued to be masked to the participant's groups at all-time intervals. Also, participants were asked not to discuss their treatment details with their peers or the outcome-measuring therapist.

研究组 & 干预措施
Ergonomic modifications group (EMG)
A blinded therapist used an observation-based ergonomics assessment check list for office workers to check the status of office environment, which usually took 40 - 45 minutes to complete. It consists of 5 domains. After assessment required modifications were done in the chair, desk, keyboard, mouse, computer screen, telephone and the office environment. Ergonomic education and instructions were also given on an individual basis as per the report of the assessment.
干预措施: Ergonomic modifications (Biological)
Physiotherapy group (PTG)
First of all, hydro collator pack was applied over the neck region for 10 minutes to relax the muscles of the neck region. Then the therapist located the sites of abnormal changes in each vertebra and then cervical manipulation was given. If any participant reported any new red flag signs or showed no signs for manipulation, such as no pain or musculoskeletal dysfunction, then the procedure was not performed.

Control group (CNG)
Participants in the CNG group received the patient education through an experienced physiotherapist and each session lasting for 30 minutes for 4 weeks. According to each individual patients' abilities the therapist educated them to improve the health literacy regarding the condition. The therapist educated them about the benefits of self-care activities, maintaining good posture, stay active and doing active movements and stretching muscles for preventing the health related musculoskeletal injuries at the workstation. Also, life style modifications were taught to the patients to prevent further deterioration of the condition.
干预措施: Patient education (Biological)
