We investigated tlle correlations between the bone stiffness index and activities of daily living (MDL) of aged women. We examined 53 Japanese women, whose mean age was 80.65.0 years. To deteImine bone stiffness, we used a Lunar tdtrasonic bone measuring instnlment. The degree of dementia was checked by Hasegawa's Questionnaire. The bone stiffness index of outpatients is higher than the bone stiffness index of inpatients. People with normal walking abilities fuld tllerefore comparatively high seLFreliance have a ltigher bone sfffness index than handicapped women. The bone stiffness index of tlle subjects who were getting on their feet is higher than that of subjects with low self-reliance.There is no conelation bertveen the degree of dementia and bone stiffness index. The physical stimuli to the bone snucture of subjects with high self-reliance in everyday-living is high, therefore sdficiently contributing preservation of bone stiffness.
