自从罗马尼亚神经病学者Marinsco和Rodorici 1920年于皮层脑干束广泛受损的肌萎缩性侧索硬化症患者检出此征以来,该反射得到广泛的研究。但其发生机理和临床价值尚未完全清楚.健康人中掌颊反射的阳性出现率差异甚大。为了解健康的中老年人掌颏反射的出现率我院于1983年4～6月,对410名中老年人进行键康体检的同时,作了本反射的调查。对象方法及结果410名系在职/退休干部,且均无脑部的器质性病变。男性400人,
This reflex has been extensively studied since this finding was detected in patients with amyotrophic lateral sclerosis, extensively impaired by romanian neuropathologist Marinsco and Rodorici in cortical brain stem tracts in 1920. However, its mechanism of occurrence and clinical value have not yet been completely understood, and the positive incidence of palmar reflex in healthy people varies greatly. In order to understand the appearance of the palm and chin reflexes of healthy middle-aged and elderly people, we conducted a survey on this reflex while carrying on the key health examination of 410 middle-aged and elderly people from April to June of 1983. Methods and Results of Objectives 410 were employed / retired cadres, and no organic brain lesions. 400 men,
