Parenchymal echogenicities that break down into extensive cystic lesions are generally followed by severe motor deficit. However, the effect of echodensities in the periventricular white matter, so called 'flares', on later development is less well documented. The aim of the present study was to investigate the impact of neonatal flares in preterm infants on neurological status and motor competence at 6 years of age and to see to what extent outcome was related to duration of flares. Forty four children with flares, subdivided into three groups according to the duration of flares, and 62 children with normal scans were assessed on Touwen's neurological examination, the Movement ABC, and the British Ability Scales. No differences in cognitive abilities were found between the groups. The results of the motor assessments showed that performance decreased significantly with increasing duration of flares. In addition, there was a suggestion that this trend was stronger in measures assessing lower limb function than those of upper limb. Teachers were also able to identify differences between the groups of children on the basis of their motor performance in school.
实质回声若分解为广泛的囊性病变，通常会伴有严重的运动功能缺损。然而，脑室周围白质中的回声密度，即所谓的“光斑”，对后期发育的影响记录较少。本研究的目的是调查早产儿新生儿期光斑对6岁时神经状态和运动能力的影响，并观察结局在多大程度上与光斑持续时间相关。44例有光斑的儿童，根据光斑持续时间分为三组，62例扫描正常的儿童接受了图温神经检查、运动ABC测试和英国能力量表评估。各组之间在认知能力上未发现差异。运动评估结果显示，随着光斑持续时间的增加，表现显著下降。此外，有迹象表明，在评估下肢功能的指标中，这种趋势比评估上肢功能的指标更强。教师也能够根据儿童在学校的运动表现识别出各组之间的差异。
