简要总结
This study evaluates a workstation ergonomics program at Al-Baha University aimed at reducing work-related musculoskeletal symptoms among university employees who use computers regularly. The program includes an ergonomics self-assessment of the workstation, individualized guidance on proper workstation setup and posture, and practical recommendations to improve daily work habits. Participants will be followed for approximately four weeks, and changes in musculoskeletal symptoms and related outcomes will be assessed before and after the program, compared with a usual-practice control group.
详细描述
This was a four-week, two-arm, parallel-group, open-label randomized controlled trial conducted among university employees at Al-Baha University. Eligible participants were randomized to either a workstation ergonomics intervention group or a usual-practice control group. Assessments were conducted at baseline and at the 4-week follow-up. The intervention consisted of a structured workstation ergonomics package including a computer workstation self-assessment checklist, individualized feedback and practical recommendations to optimize workstation arrangement and working posture, and brief reminders to support adherence during the follow-up period. The primary objective was to evaluate whether the ergonomics program reduced musculoskeletal symptom burden compared with usual practice in a real-world university workplace setting.

- •Able to read and complete the online questionnaire and provide informed consent.
排除标准
- •Current severe musculoskeletal disorder or recent major injury/surgery that markedly limits daily activities or requires ongoing medical treatment.

- •Pregnancy (if you prefer to exclude it).
- •Participation in another ergonomics intervention program during the study period.
研究组 & 干预措施
Ergonomics Program (Intervention)
Participants will receive an office-workstation ergonomics program including a self-assessment checklist-based evaluation and tailored recommendations for workstation adjustment and safe working posture, along with brief educational guidance and periodic follow-up reminders during the study period.
干预措施: Workstation Ergonomics Program (Behavioral)
Usual Practice (Control)
Participants will continue their usual workstation practices during the study period and will not receive the ergonomics recommendations/education until after completion of follow-up assessment.
干预措施: Usual Practice (Control) (Behavioral)
结局指标
主要结局
Change in number of painful body regions
时间窗: Baseline and 4 weeks.
Change from baseline to the 4-week follow-up in musculoskeletal symptom burden, operationalized as the number of body regions with self-reported musculoskeletal pain or symptoms during the previous 7 days, assessed using the Nordic Musculoskeletal Questionnaire (NMQ). Higher values indicate a greater musculoskeletal symptom burden. Outcomes will be compared between the intervention and control arms.
Change in musculoskeletal symptoms (Nordic Musculoskeletal Questionnaire [NMQ])
时间窗: Baseline and 4 weeks.
Change from baseline in musculoskeletal symptom burden measured using the Nordic Musculoskeletal Questionnaire (NMQ). The outcome will be calculated as the number of body regions with self-reported musculoskeletal symptoms (Yes/No) during the last 12 months, summed across assessed regions (range: 0 to 8, where 0 = no symptoms in any region and 8 = symptoms in all regions). Higher values indicate worse musculoskeletal symptoms. Outcomes will be compared between the intervention and control arms.
次要结局
- Change in workstation ergonomic quality score(Baseline and 4 weeks)
- Change in total musculoskeletal pain severity score(Baseline and 4 weeks)
- Change in workstation ergonomics score (Computer Workstation Ergonomics: Self-Assessment Checklist)(Baseline and 4 weeks)
