4个月～5岁正常儿童大运动功能的发育进程研究

Development of the Gross Motor Function in Normal Children

为了探讨正常儿童的大运动功能发育进程.方法 对620例4个月～5岁正常儿童的运动功能发育以量化法进行评价.结果2岁前是儿童大运动发育的关键时期,～12个月卧位运动基本完成(98±4分)、坐位运动大部分完成(87±3分),～18个月爬、跪及站位运动多数完成(分别为85±15、68±22).而走、跑、跳及攀登运动则发育较晚,～2岁仅62±12分.总公平均为3.92±0. 21分/月.其中翻身、独坐～9个月完成,腹爬(匍爬)～13个月完成,独站～18个月完成,独走～25个月完成.结论

To investigate the gross motor function development in normal children. Methods We had analysed quantitatively the score of the gross motor function Development in 620 normal children, aged from 4 months up to 5 years old. Results The key period of the gross motor function development was in the first 2 years of life. Up to 12 months, all the motor function on prone and supine position (evaluated score are 98±4 score) and most function on sitting positon(87±3 score) had been finished. Up to 18 months crawling and kneeling (85± 15) ,standimg (68±22) could be done mostly. But the abilities of walking, runing, jumping and climbing were later and their score was only 62± 12 until 2 years. The total score was 3. 92±0. 21/per month average-ly. The rolling and independent sitting were achieved up to 9 months, Creeping on stomach up to 13 months, independent standing up to 18 months, independent walking up to 23 months. Conclusions Age at acquisition of the main motor functionis a mark to judge whether is normal or not for the motor function development of the infants.
