Evaluation of Foot Deformity according to the Occupational Condition in the Labor of the Industry

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the correlation between each variable on occupational condition and foot deformity by Harris mat footprint. METHOD: Subjects were 227 labors having no neurologic or musculoskeletal problems. They were evaluated by clinical history and Harris mat footprint. Three optional parameters of footprints were medial arch angle, metatatarsal arch grade, and hallux valgus angle. RESULTS: 1) Hallux valgus angles were significantly increased in group of female, above 39 years old, labor, and duration of duty more than 6 years. 2) Medial arch angles were significantly decreased in female, above 39 years old, obese person, and labor. 3) Metatarsal arch grades were significantly increased in group of female, above 39 years old, and more than 20 numbers of conveyance, less than 6 years of duration of duty. Foot pain was not related to medial arch angle, metatatarsal arch grade, and hallux valgus angle, respectively. CONCLUSION: These results suggest that deformity of foot were related to female, above 39 years old, obese person, position of duty, duration of duty, and standing time. So these peoples maybe helpful for weaning proper modified shoes.
