Lateral preferences were determined by postal questionnaire for 240 children, without major neurological impairment, who were born at less than 31 weeks' gestation to examine the association between neonatal brain injuries and later lateral preference. Left hand preference was reported in 64 (26.7%) children at a median age of 52 months (range: 24-104 months). Left foot preference was shown by 70 (29.2%) and left eye preference by 86 (35.8%). Significantly more preterm children were left handed compared with parents or siblings in whom expected frequencies of left handedness were found. All index children had serial neonatal cerebral ultrasound examinations, of which 95 were abnormal. Left preference occurred at similar frequencies in those with normal neonatal scans (26.9%), bilateral lesions (28.3%), left sided lesions (23.8%), and right lesions (23.8%). Lateral preference appears to be unaffected by the side or extent of neonatal brain injury in children without major impairments.
通过邮寄问卷的方式，对240名出生时孕周不足31周、无严重神经功能障碍的儿童进行了利手偏好调查，以研究新生儿脑损伤与后期利手偏好之间的关联。在中位年龄为52个月（范围：24 - 104个月）的儿童中，有64名（26.7%）报告为左利手。70名（29.2%）表现为左利足，86名（35.8%）表现为左利眼。与父母或兄弟姐妹相比，早产儿童中左利手的比例显著更高，而父母或兄弟姐妹的左利手预期频率处于正常范围。所有受试儿童均接受了系列新生儿脑部超声检查，其中95例检查结果异常。在新生儿扫描正常的儿童（26.9%）、双侧病变的儿童（28.3%）、左侧病变的儿童（23.8%）和右侧病变的儿童（23.8%）中，左利偏好的出现频率相似。对于无严重功能障碍的儿童，利手偏好似乎不受新生儿脑损伤的部位或程度影响。
