Description

<p>The purpose of this study was to examine the relationship between objective and subjective assessments for declines of physical performances and oral function in elderly and to verify the siginificance of oral function and its subjective assessments as consciousness. Methods: The participants were 225 older adults. Maximum occlusal force, as indicators of oral frailty; and grip strength and walking speed, as indicators of physical frailty, were measured. Regarding the subjective assessments, 4 types of consciousness: “chewing well”, “legerity of walking”, “less fatigability”, and “much activity” were assessed by asking the present level when the level was assumed to be 100 at 20-year-old. The assessments on “chewing well”and “much activity” were comparatively high, then followed by “legerity of walking” and “less fatigability”. The siginificant relationships between the objective walking speed and subjective “legerity of walking” and between the objective occlusal force and subjective “chewing well” were found. The siginificant relationship of the objective walking speed with subjective “less fatigability, and “much activity” were found, but no relationship of the objective occlusal force was found. It is suggested the relationship between the objective and subjective assessments for occlusal force would be different from that of other physical performance, thus objective and subjective assessments on chewing would be required in the considerations of frailty.</p>
