| Abstract |
Background
: Musculoskeletal symptoms, such as pain, numbness, and ganglions on involved joints were common problems in repetitive job workers, who exposed to prolonged, repetitive use of the wrist in factory. This study was performed to compare the degree of musculoskeletal symptoms and prevalence of soft tissue mass (esp. ganglion on wrist) in repetitive job group with those of non-repetitive job group and to evaluate the association of development of ganli-on and the duration of wrist use.
Methods : Study subjects were 253 workers who work on a brick manufacturing factory and they were composed of 153 non-repetitive job workers and 100 repetitive job workers. Authors conducted a questionnaire survey among workers in the factory and examined their lesions.
Results : There were no significant difference statistically in age, level of education and work duration in both groups. It was statistically significant that the degree of wrist use was more frequent in repetitive job group than in non-repetitive job group(P<0.01). Musculoskeletal symptoms, such as pain and numbness on affected joints were more common in repetitive job group than in non-repetitive job group. Affected side was bilateral in three joints and right only in two joints(P<0.01, P<0.05). The prevalence of ganglions in repetitive job group(6 subjects, 6.0%) was much higher statistically than that in the non-repetitive job group(2 subjects, 1.3%). In a comparison of two groups according to the existence of ganglions, no stasistically signifi-cant differences were found in age, level of education and work duration. However, duration of wrist use was statistically significant relation with development of wrist ganglions(P<0.05). The 8 subjects with ganglion on wrist all worked manufacturing part in the factory. The duration of work ranged from two to fourteen years. The affected sides of ganglions on wrist were right In 3 cases and left in 5 cases. Size of ganglions ranged from 0.5 to 3 cm in diameter. Painful symptom in the ganglion was complained by two cases(25%) among 8 cases.
Conclusion : We suggest that prolonged, repetitive activities such as carrying a brick, have tendency to develop musculoskeletal symptoms and ganglions in the workers. Because high prevalence of ganglions in this factory seems to be an importnt occupational problem among repetitive job workers, further studies on the factors contributing to development of ganglions in this factory are needed. |

연구배경 : 최근 들어 반복적이고 지속적으로 힘을 가하는 분업화된 작업 공정에 근무하는 근로자들에게서 상지의 근육, 인대, 신경에 장해를 유발한다는 연구가 증가하고 있다. 특히 단순반복동작으로 인한 근골격계 질환은 향후 문제시될 직업성 질환으로 주목받고 있다. 본 연구는 한 인조석 생산공장에서 연와를 드는 반복공정에 참여하는 근로자에게 발생한 근골격계 증상과 결절종에 관해 그 실태를 파악하고 작업양상과 유의한 연관성을 조사함으로써 이에 대한 적절한 대책을 수립하고 예방함에 목적이 있다.
방법 : 1996년 5월 20일부터 22일까지 3일간 포항지역 한 단열재 및 인조석 생산공장 근로자 253명을 대상으로 253명에게 설문조사(연령, 성별, 교육수준, 근무기간, 직종, 작업내용)를 시행하였고, 연부조직 종양이 있는 근로자 24명에 대해서는 연부조직 종양의 발병일시, 발생부위, 크기 등의 설문조사와 이학적 진찰 및 천자검사를 시행하였다.
결과 : 대상자 253명이 설문조사에 참여하였고, 두 군간의 연령별, 교육수준별, 근무기간별 분포는 유의한 차이가 관찰되지 않았으나, 손목사용정도는 반복 작업군에서 사용이 더 많은 것으로 관차되었다(P<0.01). 저리거나 아픈 증상도 반복 작업군에서 더 많이 호소하였고, 특히 우측에서 0%(6명)로 비반복 작업군에서의 1.3%보다 유의하게 높았다(P<0.01).
결론 : 손몬 결절종의 발생은 손목 사용기간의 유의한 연관성을 보였고, 연와를 드는 반복작업시 손목 결절종의 발생과 근골격계 증상을 호소할 가능성이 높으므로 이를 줄이기 위한 작업 공정의 인체 공학적 고려와 조기에 환자를 발견하기 위한 선별기준이 필요할것으로보인다. |
