Abstract
PURPOSE
This pilot study compared temporal coordination during a precision grip task between 13 children and adolescents with autism spectrum disorders (ASD) who were high functioning and 13 peers with typical development.
METHODS
Temporal coordination between grip and load forces was measured using latency between onset of grip and load forces, grip force at onset of load force, peak grip force (PGF), and time to PGF.
RESULTS
Compared with peers with typical development, participants with ASD demonstrated prolonged latency between grip and load forces, elevated grip force at onset of load force, and increased movement variability. PGF and time to PGF were not significantly different between the 2 groups.
CONCLUSIONS
These findings indicate temporal dyscoordination in participants with ASD. The findings also enhance our understanding of motor coordination deficits in persons with ASD and have theoretical as well as clinical implications.
摘要
目的
本试点研究比较了13名高功能自闭症谱系障碍（ASD）儿童和青少年与13名发育正常的同龄人在精确抓握任务中的时间协调性。
方法
通过测量抓握力和负载力开始之间的延迟、负载力开始时的抓握力、峰值抓握力（PGF）以及达到PGF的时间来测量抓握力和负载力之间的时间协调性。
结果
与发育正常的同龄人相比，患有ASD的参与者在抓握力和负载力之间的延迟延长，负载力开始时的抓握力升高，运动变异性增加。两组之间的PGF和达到PGF的时间没有显著差异。
结论
这些发现表明患有ASD的参与者存在时间不协调。这些发现还增进了我们对ASD患者运动协调缺陷的理解，并具有理论和临床意义。
