The effect of 3 hours of ambulatory activity on the mental function of 12 elderly persons with postural hypotension was examined. There was little difference between the mean combined mental status and set test scores when the subjects were supine (42.3) and when they were erect after 3 hours of ambulatory activity (42.2). A control group of persons of similar age and health who did not have hypotension also exhibited little difference in mean scores (49.9 v. 51.5 respectively). The mean scores of the two groups of subjects did not differ significantly. After 6 months the mean scores of the two groups were 40.9 and 44.7 respectively. It appears that elderly individuals with postural hypotension do not exhibit any appreciable deterioration in mental function with ambulation or after a 6-month period.
研究了3小时动态活动对12名患有体位性低血压的老年人心理功能的影响。当受试者仰卧时（平均综合心理状态和成套测试分数为42.3）以及在进行3小时动态活动后直立时（42.2），平均综合心理状态和成套测试分数之间几乎没有差异。一组年龄和健康状况相似但没有低血压的对照组在平均分数上也几乎没有差异（分别为49.9和51.5）。两组受试者的平均分数没有显著差异。6个月后，两组的平均分数分别为40.9和44.7。看来，患有体位性低血压的老年人在行走或6个月后，其心理功能并未出现明显恶化。
