Changes in the morphology and functioning of the speech articulators were assessed in 118 children monitored from the age of 7 to 10 years, and associations between these variables and misarticulations were analyzed. The accuracy of articulatory movements and their coordination improved markedly. There was a relative delay in development of the motor coordination of boys who produced sounds too far posteriorly. Difficulties in tongue movements and their coordination increased the risk for the category of other misarticulations. Difficulties in motor coordination contributed to a lesser extent to articulatory speech disorders in 10-year-olds compared to 7-year-olds. Some new cases of inaccuracy of coordinating the movements refer to the liability of muscle coordination still at the age of 10.
对118名从7岁到10岁接受监测的儿童的言语发音器官的形态和功能变化进行了评估，并分析了这些变量与发音错误之间的关联。发音动作的准确性及其协调性有显著提高。发出声音过于靠后的男孩在运动协调发展方面存在相对延迟。舌头运动及其协调性方面的困难增加了其他发音错误类型的风险。与7岁儿童相比，运动协调困难对10岁儿童的发音言语障碍影响较小。一些运动协调不准确的新病例表明，即使在10岁时肌肉协调仍存在易感性。
