Summary
Fifty percent of poultry workers showed abnormal upper extremity findings, with many experiencing impaired pinch strength and reduced fingertip sensitivity. This study highlights the need for early detection of work-related musculoskeletal disorders.
Area of Science:
- Occupational Health
- Ergonomics
- Musculoskeletal Disorders
Background:
- Repetitive tasks in poultry processing are associated with high rates of upper extremity disorders.
- Early detection and intervention are crucial for managing work-related musculoskeletal disorders (WMSDs).
Purpose of the Study:
- To assess the prevalence of abnormal upper extremity findings in poultry processors.
- To evaluate a measurement method for preclinical detection of these disorders.
Main Methods:
- On-site testing of 157 poultry processors.
- Assessment of 22 possible upper extremity findings.
- Analysis of objective signs and subjective symptoms.
Main Results:
- 50% of workers had three or more abnormal findings; the average worker had 5-6.
- Impaired pinch strength, decreased vibration sensitivity, and numbness were most common.
- 25% of workers with signs reported no symptoms, while 8% reported symptoms without signs.
Conclusions:
- The measurement method is useful for assessing worker populations and detecting preclinical signs of CTDs.
- Early detection can potentially reduce medical costs and minimize disability.
- Accurate measurement is essential for effective prevention strategies.
