Abstract

Purpose: Evoked potentials were recorded in patients with DCD to evaluate the integrity the afferent pathways and to rule out the presence of any neurological lesions.

Material and methods: Two boys: 5 and 16 years old with recognized DCD were examined. Battery of tests: short-latency somatosensory evoked potentials (SEP), pattern-reversal visual evoked potentials (VEP), cognitive event-related potentials (CERP) and EEG were recorded. CT and neuropsychological assessment were also performed.

Results: N20 and P25 latencies and also central conduction time of SEPs in both patients were longer. N9, N11, N13 latencies were normal. VEP, CERP, EEG and neuroimaging scans were normal.

Conclusions: Relationship among perceptual--motor skills, cognitive impairment and electrophysiologic findings in children with developmental dyspraxia are discussed. The disturbances of the integrity of the afferent pathways could to be one of many causal factors. Further researches are required to determine the specific source of the neurological deficit of clumsy children.

发育协调障碍儿童的皮质诱发电位。

目的:记录DCD患者的诱发电位，以评估传入通路的完整性，并排除任何神经病变的存在。材料与方法:对2例确诊DCD的5岁和16岁男孩进行检查。记录短潜伏期体感诱发电位(SEP)、模式反转视觉诱发电位(VEP)、认知事件相关电位(CERP)和脑电图。同时进行CT和神经心理评估。结果:两组患者的N20、P25潜伏期和中枢传导时间均较长。N9、N11、N13延时正常。VEP, CERP，脑电图和神经成像扫描正常。结论:本文讨论了发展性运动障碍儿童知觉运动技能、认知障碍和电生理表现之间的关系。传入通路完整性的紊乱可能是许多原因之一。需要进一步的研究来确定笨拙儿童神经缺陷的具体来源。
