• Coordination Pattern of Perioral Muscles during Sucking in Infants; Analysis of the EMG mean integration curve

抄録

The purpose of the present study was to investigate the change in the coordination pattern of the perioral muscles from the temporalis (TM), masseter (MM), orbicularlis oris (OM) and suprahyoid muscles (SM) in the sucking cycle during breast feeding in infants after birth from one to six months and the weaning period, and to discuss the differences between breast and artificial nipple feeding.<BR>A total of sixty-two infants were innvolved in the study. For the EMG parameters, the sucking cycle time (ms), the peak amplitude (μV⋅s), and the peak time (ms) and the peak time ratio (%) which were measured from the onset of the sucking cycle to the point of the highest amplitude of each muscle activity on the EMG mean integration curve, were examined.<BR>The following results were obtained:<BR>1) The mean sucking cycle time of the breast-fed infants was 632.3 ms, while there were no significant differences among the number of months after birth.<BR>2) Based on the peak time and the peak time ratio analysis, it was found that the TM, MM, OM were activated in the first half and the SM was activated in the latter half of the sucking cycle. For the order of the muscle bursts were the TM and OM activated first followed by the MM and SM.<BR>3) There were no significant differences in the sucking cycle time and the peak time between the breast and artificial nipple feeding.<BR>4) The peak amplitude of the SM was generally the highest, followed by the OM, the TM and the MM during both the breast and artificial nipple sucking.<BR>It was concluded that the stable coordination pattern of the perioral muscles was recognized in the sucking cycle and the coordination pattern was not influenced by either the number of months after birth and the type of nipples.
