Abstract
PDF - OBJECTIVES
The main purpose of this study was to investigate relationship between cumulative trauma disorders(CTDs) and the types of workstation and chair in workers with repetitive motion tasks.
METHODS
The study subjects were 77 repetitive motion tasks workers at small manufacturing industries in Seoul and Gyung-gi district area. A questionnaire was used to obtain about health practice for prevention and prevalence of CTDs by worker. The type of Workstations and chairs in workers were measured and analyzed with prevalence of CTDs by logistic regression.
RESULTS
Eighty-six percent of workers recognized that work posture was related to workstation and chair. Most employers and employees didn't follow the work practice guidelines for workers with repetitive motion tasks. The prevalence of CTDs was 64% by questionnaire. The prevalence of pain in shoulder, neck, back, and arm were 38%, 15%, 6%, and 5%, respectively, and the pain started after working an average duration of 16.5 months. The CTDs symptoms were significantly related to thickness of workstation, height of workstation, length of knee depth under workstation, height of back rest, height of seat pan, depth of sitting surface, width of sitting surface, and length from workstation surface edge to shoulder. By multiple regression analysis of each risk factor, prevalence of CTDs was highly correlated with height of back rest, height of seat pan, and depth of sitting surface.
CONCLUSIONS
This study suggests that workstations should be made adjustable for height and chairs should be equipped with seat pan height control, enough sitting surface for depth and width, back rest height and angle control. The workers should use the right working postures, exercise for health, occupational health education, and rest breaks and the manager of company should be educated for the preventing of CTDs. -

Abstract
PDF
- Physical examinations including muscle tenderness and neurological tests, were performed on two hundred ninety international telephone operators and their relations with work conditions and subjective symptoms were analyzed. The results obtained were as follows: 1. The prevalence of muscle tenderness was significantly higher in the shoulder and the arms than in other parts of body. 2. No difference of prevalence of muscle tenderness was noted according to the age of workers. 3. The prevalence of muscle tenderness on the shoulder and the arms significantly increased after the work duration of 5 years. 4. Muscle tenderness on the arm, the neck and the shoulder were dominant in the right side. 5. The prevalences of paraesthesia on right shoulder and right arm were higher than those on other parts of body. 6. A significant linear association was noted between the number of tender areas and positive response to questions. 7. The prevalences of positive Spurling test and Morley test were higher in the work duration group of 15 years and more. 8. It seemed that muscle tenderness examination and Morley test were more useful for the diagnosis of cervicobrachial disorders.

Abstract
PDF
- A questionnaire study was carried out on 290 international telephone operators to find Out their characteristics of musculoskeletal symptoms in relation to work conditions (work posture, work load etc.) and work duration.
Results
were as follows: 1. The C7-earhole angle, the elbow angle, the left arm abduction angle and the right arm abduction angle all did not meet the recommended criteria and, therefore, seemed to have increased the static load of muscles of the neck, the shoulder and the arms. 2. The prevalence of musculoskeletal complaints was higher in the shoulder and the arms which followed by the neck, the lower hack, the hands and fingers, the hack and the lower limbs. 3. The prevalences of musculoskeletal complaints in the hack and the lower hack increased significantly, as the work duration extended over 5 years. 4. In general, the prevalence of musculoskeletal complaints tended to be lower among habitual exercise group than others. 5. In view of the high prevalence of musculoskeletal complaints even among those with short work experience, it seemed necessary to introduce an adequate control program of cervicobrachial disorders from an early stage of employment. -
