Abstract:
Objective To investigate the characteristics of oral and laryngeal diadochokinesis abilities and the developmental patterns of coordinated vocal fold movements in preschool children aged 3～6 years.Methods Sixty-one normal preschool children aged 3～6 years were selected to measure their maximum phonation time(MPT),as well as two types of acoustic parameters of oral and laryngeal diadochokinesis ability movements,including the as-sessment of one trisyllabic/pataka/diadochokinesis ability rate and four monosyllabic/?a/,/ha/,/?A/,/hA/la-ryngeal diadochokinesis ability rates.Results Diadochokinesis ability(DDK)and laryngeal diadochokinesis ability(LDDK)rates increased with age in preschool children aged 3～6 years,showing highly significant differences(P＜0.01).The growth rate of children's LDDK rates at age 4～5 years was the maximum within the 3～6 year age range.Children's MPT was highly significantly and positively correlated with DDK and LDDK(P＜0.01).The vo-cal fold adduction capacity in laryngeal diadochokinesis ability movements in children of all age groups was greater than vocal fold adduction ability/?a/LDDK＞/ha/LDDK(P＜0.01),/?A/LDDK＞/h∧/LDDK(P＜0.05).Con-clusion Age,MPT,and vocal fold adduction and abduction status had a significant effect on the oral and laryngeal diadochokinesis ability of preschool children aged 3～6 years old.The ages of 4～5 is a critical period for the devel-opment of children's oral and laryngeal diadochokinesis ability.
