脑卒中患者主客观记忆能力对工具性日常生活活动能力的预测价值

The prediction of IADL by subjective and objective memory ability for stroke patients

目的:通过对脑卒中患者工具性日常生活活动能力与其主客观记忆能力之间关系的研究,判别影响IA DL的记忆功能因素,探讨脑卒中患者主客观记忆能力对IADL的预测价值。方法:对52例脑卒中患者用RBMT测试其客观记忆能力;采用视觉模拟评价法评测患者的主观记忆能力;用FAQ评估其IADL能力。然后用Pearson相关分析来观察IADL与主客观记忆能力的关系;再以FAQ为因变量,行多元逐步回归分析和Logistic多元逐步回归分析以探讨脑卒中患者主客观记忆能力对IAD L的预测价值。结果:①患者的主观记忆能力与RBMT呈显著正相关(P<0.05);FAQ与主观及RBMT呈显著负相关(P<0.05,P<0.01)。②多元逐步回归分析显示:RBMT中记被藏物、信封两个分项目以及RBMT总分进入方程(P<0.05),且RBMT总分是IA DL的显著预测因子(R2=0.68,P<0.001),Logistic多元逐步回归分析结果表明,对IADL能否自理的预测,仅有RBMT总分进入模型。结论:脑卒中患者的行为记忆能力对预测其在家庭和社区中的IADL水平有重要意义。

Objective:To distinguish the memory influenced factors of IADL for the patients with stroke and to explore the prediction value of IADL by subjective and objective memory ability for the patients with stroke. Method:52 cases of the patients with stroke were assessed in the study.The objective,subjective memory ability and IADL level were evaluated with RBMT,VAS and FAQ respectively.Result:①The RBMT total score was significantly positive related to the subjective memory ability for the patients with stroke(P<0.05);FAQ was significantly negative related to the subjective memory ability and RBMT(P<0.05,P<0.01).②Multiple stepwise regression analysis indicated that three factors of RBMT total score,items of the hidden matter and envelope entered the equation(P<0.05);RBMT total score was the remarkable predictive factor(R2=0.68,P<0.001).Logistic multiple stepwise regression analysis indicated that RBMT total score only entered the model to predict IADL. Conclusion:The behavioral memory ability may play an important role in predicting IADL level in the stroke patients.
