| Research Abstract |
Continuous recording during the day and at night was performed using a portable electromyogram. The characteristics of non-functional movement, primarily bruxism, occurring when awake and during sleep, as well as the relation between them, were investigated. Masticatory muscle activity when awake was weak but continuous,whereas that during sleep was strong and intermittent. Overall muscle action per unit time when awake was greater than that during sleep. It was assumed that, when functional movement is included, activity during the day significantly affects the stomatognathic system.
