The Prevalence and Ergonomic Analysis of Cumulative Trauma Disorders in the Bank Worker and Post Officer

ABSTRACT

OBJECTIVE: To survey the prevalence of Cumulative trauma disorders (CTDs) and to analyze the ergonomic factors among the bank workers and post officers. METHOD: Seventy seven subjects were collected from bank workers (50) and post officers (27) from the multiple areas of country who had been exposed to risky working environment regarding CTDs. The subjects were first screened by occupational medicine specialists and confirmed by rehabilitation medicine specialist. The serologic test, radiologic imaging, electrodiagnostic study were performed in all the subjects. Ergonomists analyzed the job element to identify the risk factors by baseline checklist of CTDs. RESULTS: Among bank workers, 30 (60%) of 50 were confirmed as having CTDs. MPS was present in 30 patients (60%), latenl epicondylitis in 5 (10%), medial epicondylitis in 3 (6.0%), tendinitis 3 (6.0%), and other disease in 3 (6.0%). Among post officers, 14 (51.9%) of 27 were confirmed as having CTDs. MPS present in 10 (37.0%), cervical disc disease in 4 (14.8%), others in 4 (14.8%). The ergonomic risk score was highest 1.87 in the 'package deviding' job, and 1.82 in 'bagging to cart', 1.62 in 'initial devision'. CONCLUSION: The result would be helpful for the prevention and management of CTDs in the bank workers and post officers.
