One hundred and ten patients with persistent vegetative state, were followed up for a period of five years from 1973 to 1978. Seventy-three per cent of the patients died during the period while about 10% of them recovered partially from the vegetative state. Among the recovered patients, only three became able to communicate, but two of these are not independent for their daily activites. Reactivity and clinical symptoms of 30 survivors were examined, but no great changes occurred during the last two years of the study.
1973年至1978年期间,对110例持续性植物状态患者进行了为期五年的随访。在此期间,73%的患者死亡,约10%的患者从植物状态中部分恢复。在恢复的患者中,只有3例能够交流,但其中2例在日常生活中不能自理。对30名幸存者的反应性和临床症状进行了检查,但在研究的最后两年中没有发生太大变化。
