Abstract

This study was on jaw tapping movements made when periodical acoustic signals at various frequencies (0.3-2.8Hz) were applied. The subjects were 10 healthy dentulous young adults with a mean age of 23.9 years. They were told to make jaw tapping movement in time to the signals. Observation was made on the relationship of MKG and acoustic signal. The results were as follows:<BR>1. In control processes, jaw tapping movements with 0.3Hz command signal were different from those with faster periodical signals. The results indicated that the former depended greatly on “an instant performance control”.<BR>2. Signal frequencies had little effect on “the maximum jaw closing velocity” and “the time relation between appearance of the maximum jaw closing velocity and tooth contact with time”.<BR>3. It was concluded that jaw tapping movements with signals of lower frequencies (about 0.3Hz) were more suitable, if early motor control and recognition is observed without taking prediction into consideration.
