精细运动发育落后幼儿视觉运动整合与视诱发电位关系探讨

目的 研究精细运动发育落后幼儿其视觉运动整合能力与视诱发电位潜伏期之间的相关性,为发育落后患儿的早期诊断和干预提供科学依据。方法 2015年1月-2016年12月选择71例经PDMS-Ⅱ测试精细运动发育落后并符合纳入标准的患儿,同时进行闪光视觉诱发电位检测,将闪光视诱发电位P100潜伏期(LP100)均值分别与视觉-运动整合能力(VMI)和精细运动发育商(FMQ)均值进行统计学检验及相关性分析。结果 精细运动发育落后幼儿视诱发电位潜伏期与视觉-运动整合及精细运动发育商存在相关关系(r=-0.859和-0.844,P<0.001),潜伏期越延迟,其视觉-运动整合标准分及精细运动发育商越低。结论 视知觉功能可影响精细运动发育落后幼儿视觉运动整合能力,视诱发电位可作为早期诊断、早期干预提供重要线索和电生理依据。

Analysis of the correlation between visual motor integration ability and visual evoked potentials in children with fine motor skills delay

Objective To investigate the association between visual motor integration(VMI) and flash visual evoked potentials(FVEPs) in children with fine motor skills delay,in order to provide scientific basis for early diagnosis and early intervention of child with fine motor skills delay. Methods Totally 71 children with fine motor skills delay diagnosed by PDMS-Ⅱ and accorded with inclusion criterion in Xi'an Children's Hospital were enrolled in this study from January 2015 to December 2016.FVEPs were performed in all children.Besides,visual motor integration(VMI) and fine motor quotient(FMQ)were assessed by PDMS-Ⅱ.And correlation between LP100 and VMI,LP100 and FMQ were analyzed. Result There were significant correlations among FVEPs,VMI and FMQ,that was higher LP100 indicated lower VMI and FMQ(r=-0.859,-0.844,P<0.001). Conclusions Visual perception has an influence on VMI in children with fine motor skills delay,and FVEPs can provide important clues and electrophysiological basis for early diagnosis and early intervention.
