任务依赖的人类运动组织在口周区域进行了检查,在八个正常的成年人进行口头任务,包括嘴唇突出,咀嚼,和讲话。计算从嘴唇周围的象限记录的EMG信号之间的零相位滞后相关性,以确定运动耦合的模式。结果表明,口周肌在输出组织中是灵活的。在突出任务期间,所有象限中的Activv高度正相关。在咀嚼任务中,相关性是中等的,在上下嘴唇两侧有更强的模式。言语任务显示出较低水平的相关性之间的象限,但同样的模式是更高度相关的双边比同侧。结果进行了比较,在人类和动物的口腔肌肉神经支配的研究,也与假设的皮质控制模式的口腔运动。
Task-dependent human motor organization in the perioral region was examined in eight normal adults who performed oral tasks including lip protrusion, chewing, and speech. Zero phase-lag correlations among EMG signals recorded from quadrants surrounding the lips were calculated in order to determine patterns of motor coupling. Results indicated that the perioral musculature is flexible in output organization. Activv in all quadrants was highly positively correlated during the protrusion task. During the chewing task, correlations were moderate, with a stronger pattern bilaterally across the upper and lower lips. The speech tasks showed lower levels of correlation among the quadrants, but again the pattern was more highly correlated bilaterally than ipsilaterally. Results are compared to studies of oral muscle innervation in humans and animals and also are related to hypotheses of cortical control patterns for oral movement.
