Summary
Sewing-machine operators experience high rates of neck-shoulder problems, with 75% reporting issues in the past year. Prolonged static work posture is linked to tension neck syndrome, impacting work and leisure time.
Area of Science:
- Occupational Health
- Musculoskeletal Disorders
- Ergonomics
Background:
- Sewing-machine operators (SMO) perform repetitive tasks leading to static muscular load on the neck and shoulders.
- High prevalence of neck-shoulder complaints is suspected in this occupational group.
Purpose of the Study:
- To investigate the occurrence and clinical picture of neck-shoulder problems in SMO.
- To identify potential correlations between work factors and these problems.
Main Methods:
- A cross-sectional study involving 224 SMO from four textile factories.
- Utilized a comprehensive questionnaire including the Nordic Ministry Questionnaire for neck-shoulder complaints.
- Clinical examinations were performed on a subset of SMO.
Main Results:
- A 12-month prevalence of 75% and a 7-day prevalence of 51% for neck-shoulder complaints were reported.
- Tension neck syndrome (TNS) was the most frequent diagnosis, followed by cervical syndrome.
- A positive correlation was found between TNS and weekly working hours, suggesting prolonged static load is a significant factor.
Conclusions:
- Neck-shoulder problems are highly prevalent among SMO.
- Prolonged static posture during work significantly contributes to the development of these issues.
- Further ergonomic interventions are recommended to mitigate risks.
