초록

The purpose of this study was to research the effects of vocalization on upper extremity motion during occupational performance and to compare non-meaning and meaning vocalization. Experiments were performed on 30 subjects. They had no medical history of neurological problems with their upper extremities. Using a tea cup, a tea tray, and a tea spoon, they set a table during vocalization. We used meaning and non-meaning vocalization with the subjects. An example of meaning vocalization would be naming something, and an example of non-vocalization would be saying, "Ah." We used a 3-D analysis system called CMS-HS. We analyzed the motion in the angular velocity and acceleration of the elbow while recording performance time. The results of this study showed that vocalization enhanced the angular velocity and acceleration of the elbow, and also enhanced performance time. In short, vocalization improved upper extremity motion by making it faster and smoother. There were no significant differences between meaning and non-meaning vocalization.
