The prevalence and severity of visual-motor deficits and the relation of visual-motor function to visual perception and fine motor skills was examined in a group of 83 neurologically and intellectually normal (IQ >84) very-low-birthweight (VLBW) children at age 5. Fifteen children (17%) had below average visual motor scores (<1SD below mean). While relatively few children (N=9) had below average scores in visual perception (11%), 58 (71%) had below average scores for fine motor skills. Nineteen (23%) were considered impaired (<1.5SD); of these, eight were severely impaired (<2SD). Fine motor scores were significantly lower in children who had been born <28 weeks' gestation, with hyaline membrane disease, or had required a longer period of ventilation. There was significant correlation between visual-motor and fine motor scores (r = 0.50, P < 0.001) and between visual-motor and visual perception scores (r = 0.42, P < 0.001). The implications of these findings and management of these 'normal' children need further research. Previous reports of visual-motor dysfunction in school-age VLBW children could be related to fine motor difficulties.
对一组83名神经和智力正常(智商>84)的5岁超低出生体重(VLBW)儿童,研究了视动功能障碍的患病率和严重程度,以及视动功能与视觉感知和精细运动技能的关系。15名儿童(17%)的视动得分低于平均水平(比均值低<1个标准差)。虽然相对较少的儿童(N = 9)视觉感知得分低于平均水平(11%),但58名(71%)儿童的精细运动技能得分低于平均水平。19名(23%)被认为有功能受损(<1.5个标准差);其中8名严重受损(<2个标准差)。孕周<28周、患有透明膜病或需要更长通气时间的儿童,其精细运动得分显著更低。视动得分与精细运动得分之间(r = 0.50,P < 0.001)以及视动得分与视觉感知得分之间(r = 0.42,P < 0.001)存在显著相关性。这些发现的意义以及对这些“正常”儿童的管理需要进一步研究。此前关于学龄期VLBW儿童视动功能障碍的报告可能与精细运动困难有关。
