Research Abstract

The work load of interpretation from speech to sign language was evaluated experimentally with 20 professional sign language interpreters, consisted of 5 healthy (Group I) , 9 slightly affected with OCD (Group II) , and 6 moderately affected (Group III).
Two kinds of tests and subjective symptom checking were conducted every 5 min that were a definite finger spelling test to observe the position and locus of the right elbow, blocking and interpretation error and unnecessary motion, and a 15-sec straight forward arm-holding test to measure the root mean square (RMS) and mean power freguency(MPF)of EMG signs in the upper trapezius muscles.
Localized muscle symptoms and a feeling of deterioration of his/her own interpretation increased in the early stage of the experiment, more markedly in Group III.Change of position and locus of the right elbow suggested the exist of a tendency to fatiguein Group III,and the exist of a tendency to exertion against to fatigue in Group I,and in Group II the midway state between this two groups, though none of these changes was significant. In EMG,a tendency to RMS increase and MPF decrease were observed : RMS increase was marked and significant in Group III,but no MPF decrease was seen in Group III.The incidence of Blocking, interpretation error, and unnecessary motion did not show any definite tendency.
