A survey of all known 18 month old Oxfordshire children who had not yet walked unassisted and who were born in the four year period between July 1, 1976 and June 30, 1980 was carried out. A total of 275 children aged 18 months with no previously suspected cause for late walking were referred by health visitors; 257 of these children were assessed neurologically and developmentally by a paediatrician at home. Nine cases of cerebral palsy (3 X 5%) and 6 cases of minor neurological abnormality (2 X 3%) were newly diagnosed. A register of all other 18 month old 'late walkers' (129) who were already known to paediatricians and were either normal (17) or had known causes for late walking (112) was compiled for the same four year period. The total incidence of pathology among all late walkers (404) in these two groups was 32%.
对所有已知的18个月大、尚未独立行走且于1976年7月1日至1980年6月30日这四年期间出生的牛津郡儿童进行了一项调查。共有275名18个月大、此前无迟行可疑病因的儿童由保健访视员转诊；其中257名儿童由一名儿科医生在家中进行了神经学和发育方面的评估。新诊断出9例脑瘫（3×5%）和6例轻度神经异常（2×3%）。编制了一份在同一四年期间所有其他已为儿科医生所知的18个月大“迟行者”（129名）的登记册，这些儿童要么正常（17名），要么有已知的迟行病因（112名）。这两组中所有迟行者（404名）的病理总发生率为32%。
