Objective To study the effect of ladder language training on vocabulary comprehension of children with Down syndrome(DS).Methods Fifteen DS children aged 10～18 years(average 13.89±2.42 years)were in-cluded as the experimental group and 15 DS children aged 10～18 years(average 13.56±1.81 years)were recruited as the control group.The intelligence level of the two groups was evaluated by China Binet-Simon intelligence test.The vocabulary comprehension ability of two groups of children was evaluated by Peabody picture vocabulary test re-vised(PPVT-R).The physiological age,intelligence level and vocabulary comprehension ability before intervention were matched between the two groups.The children in the experimental group had 16 ladder language training twice a week,45 minutes each time by group intervention for 16 times.The children in the control group did not receive this kind of intervention.Through comparison,the effect of ladder language training on DS children's vocabulary comprehension ability was analyzed.Results There was no significant difference in PPVT-R scores between the ex-perimental group(39.6±11.04)and the control group(39.93±10.61)before training(P＞0.05).After training,the PPVT-R score of DS children in experimental group(48.53±11.23)was significantly higher than that in con-trol group(40.2±10.63)(t(28)=2.086,P＜0.05)and was extremely significantly higher than that before training(39.6±11.04)(t(14)=-8.956,P＜0.001).There was no significant difference in PPVT-R scores between DS children in the control group before and after training(t(14)=-1.468,P＞0.05).The scores of children's under-standing abilities of nouns,verbs and adjectives in DS group after training were all higher than 80％,which was sig-nificantly higher than that before training(P＜0.001).Conclusion Ladder language training can significantly im-prove the vocabulary comprehension ability of DS children.
