[Study of workload and cervicobrachial disorder among sign language interpreters].
We conducted a nationwide questionnaire study on the workload and health conditions of professional sign language interpreters to investigate the relationship between occupational cervicobrachial disorders (OCD) and the sign language workload. The number of valid respondents was 542 (92.3%), 85.8% of them females. They were employed by the national or local governments or organizations for the disabled. The complaint rates of subjective symptoms involving the neck, shoulders, arms, fingers, eyes and ears, being equal or higher than the rates reported for cashiers, telephone operators and nursery school teachers when OCD occurred frequently. As the workload of sign language increased, the number of complaints of symptoms in the cervicobrachial region, which also includes fingers, increased as well. Occupational safety and health management for preventing OCD should be carried out immediately for sign language interpreters.
