A GAME-LIKE DUAL-TASK EXERCISE MAY SAVE THE OLDEST-OLD WOMEN FROM THE COGNITIVE DECLINE

摘要

We investigated an effect of a new cognitive and motor dual-task performance (DT) intervention called ‘Synapsology’ program (SYNAP) for the oldest-old women living in nursing home. Subjects (n=15) were aged 85 to 95 (mean: 89.5 ± 3.3) and we received the agreement of the subjects and their guardians. Participants carried out DT for 30 min once a week for 48 weeks. (1 to 24 weeks: the program with the professional instructors, 25 to 48 weeks: self-exercise based on the same program performed before). Evaluation items were in the cognitive function by mini mental state examination (MMSE) and in the physical function by grip strength, one-leg balance with eyes open and 6-m habitual walk test. The statistical method used Friedman test and the difference was judged as P<0.05. Statistically significant improvements (P=0.02) were observed in the cognitive function (MMSE median: 26; 29; 28 score, respectively) from pre-, mid and post test. There was no statistically significant change in physical function (grip strength median: 12.65; 14.00; 12.25 kg, respectively (P=0.12), one-leg balance with eyes open medina: 3.16; 5.57; 2.76 s, respectively (P=0.69), 6-m habitual walk test median: 7.5; 7.6; 6.9 s, respectively (P=0.30)). The cognitive and physical function in the oldest-old women were shown the significant improvement or maintenance by SYNAP intervention for one year, and there were no dropout subjects. Therefore, it can be suggested that a new DT exercise program is an effective cognitive and physical function program for the oldest-old women living in nursing home.
