The glabellar tap reflex has been studied in 88 adults with mental retardation and 20 normal controls. None of the 20 controls had abnormal response to glabellar tap. All the subjects with mental retardation had abnormal response to glabellar tap, 80 subjects had 'no habituation' and eight subjects had 'poor habituation' of response to glabellar tap. Thirty-nine subjects, with Down's syndrome, Prader-Willi syndrome and with gross cerebral pathological states with or without motor deficits had 'no habituation' of response to glabellar tap. Of the remaining 49 subjects with unidentified aetiological diagnosis of mental retardation, 41 subjects had 'no habituation' and eight subjects had 'poor habituation' of response to glabellar tap. Age and sex had no significant effect on the response to glabellar tap in the subjects studied. The possible physiological mechanisms responsible for the abnormal response to glabellar tap have been discussed.
对88名成年智障者和20名正常对照者进行了眉间轻叩反射研究。20名对照者中无人对眉间轻叩有异常反应。所有智障受试者对眉间轻叩均有异常反应，80名受试者对眉间轻叩“无习惯化”，8名受试者对眉间轻叩“习惯化不良”。39名患有唐氏综合征、普拉德-威利综合征以及有或无运动缺陷的严重脑部病理状态的受试者对眉间轻叩“无习惯化”。在其余49名病因诊断不明的智障受试者中，41名受试者对眉间轻叩“无习惯化”，8名受试者对眉间轻叩“习惯化不良”。年龄和性别对所研究受试者的眉间轻叩反应无显著影响。文中讨论了导致对眉间轻叩异常反应的可能生理机制。
