BACKGROUND/AIMS: Specific language impairment (SLI) is characterized by deficits in language ability. However, studies have also reported motor impairments in SLI. It has been proposed that the language and motor impairments in SLI share common origins. This exploratory study compared the gross, fine, oral, and speech motor skills of children with SLI and children with typical development (TD) to determine whether children with SLI would exhibit difficulties on particular motor tasks and to inform us about the underlying cognitive deficits in SLI.
A total of 13 children with SLI (aged 8-12 years) and 14 age-matched children with TD were administered the Movement Assessment Battery for Children - Second Edition and the Verbal Motor Production Assessment for Children to examine gross and fine motor skills and oral and speech motor skills, respectively.
Children with SLI scored significantly lower on gross, fine, and speech motor tasks relative to children with TD. In particular, children with SLI found movements organized into sequences and movement modifications challenging. On oral motor tasks, however, children with SLI were comparable to children with TD.
Impairment of the motor sequencing and adaptation processes may explain the performance of children with SLI on these tasks, which may be suggestive of a procedural memory deficit in SLI.
背景/目的:特定语言障碍(SLI)的特征是语言能力缺陷。然而,研究也报告了SLI患者存在运动障碍。有人提出,SLI中的语言和运动障碍有共同的起源。这项探索性研究比较了SLI儿童和发育正常(TD)儿童的粗大运动、精细运动、口腔运动和言语运动技能,以确定SLI儿童在特定运动任务上是否会表现出困难,并让我们了解SLI潜在的认知缺陷。
对13名SLI儿童(8 - 12岁)和14名年龄匹配的TD儿童分别进行了儿童运动评估量表第二版和儿童言语运动产生评估,以检查粗大运动和精细运动技能以及口腔运动和言语运动技能。
相对于TD儿童,SLI儿童在粗大运动、精细运动和言语运动任务上的得分显著更低。特别是,SLI儿童发现将动作组织成序列和改变动作具有挑战性。然而,在口腔运动任务上,SLI儿童与TD儿童相当。
运动序列和适应过程的损伤可能解释了SLI儿童在这些任务上的表现,这可能暗示SLI存在程序性记忆缺陷。
