Musculoskeletal complaints in lock assemblers, testers and inspectors

Area of Science:

• Occupational Health
• Epidemiology
• Musculoskeletal Disorders

Background:

• Assessing musculoskeletal complaints in industrial workers is crucial for understanding occupational health risks.
• Lock assemblers represent a specific workforce potentially exposed to unique ergonomic stressors.

Observation:

• A survey of lock assemblers in the West Midlands utilized an adapted Nordic Musculoskeletal Questionnaire.
• Data collection spanned 12 months, examining annual and weekly prevalence and disability rates.
• Comparisons were made across six companies and over time within one company (Site 4).

Findings:

• Overall high levels of self-reported upper limb complaints were identified in lock assemblers compared to referent groups.
• Site 4 showed increased reporting of neck, upper back, and hip symptoms prior to the initial study.
• One year later, new employees at Site 4 reported significantly fewer neck and elbow complaints, but wrist complaints remained unchanged.

Implications:

• The findings highlight a significant burden of upper limb musculoskeletal complaints in the lock assembly industry.
• The reduction in symptoms among new employees at Site 4 suggests that workplace factors or adaptation may influence complaint rates.
• Further research into specific ergonomic factors and targeted interventions is warranted to mitigate these occupational health issues.
