Abstract

<p>本研究の目的は,プレサルコペニア高齢者の歩行速度と身体機能および認知機能との関連を検討することである。対象者を正常筋肉量群(48名)とプレサルコペニア群(17名)の2群に分類し,歩行速度(通常・最速)と身体機能(膝伸展筋力,上体起こし,開眼片足立ち時間,長座体前屈距離)および認知機能(Mini-Mental State Examination, Trail making test-Part A; TMT-A)との相関分析を行った。その結果,プレサルコペニア群の通常歩行速度と中程度以上の有意な相関が認められたのは,膝伸展筋力(r=0.51)およびTMT-A(r=-0.52)であり,最速歩行速度では膝伸展筋力(r=0.74),TMT-A(r =-0.66)および開眼片足立ち時間(r=0.56)であった。一方,正常筋肉量群の歩行速度はいずれの項目とも中程度以上の有意な相関は認められなかった。これらの知見より,プレサルコペニア高齢者は正常筋肉量の高齢者に比べ努力性の高い歩行である可能性が示され,下肢筋力,バランス能力および注意機能のわずかな低下をきっかけに歩行能力低下を生じる可能性が示唆された。</p>

<p>The objective of this study was to analyze the association between gait speed and physical function as well as cognitive function in elderly individuals with presarcopenia. Subjects were divided into the normal muscle mass group (n=48)andthepresarcopenia group (n=17). We performed a correlation analysis of gait speed (usual/maximum gait speed) with physical function (knee extension strength, sitting-up, one-leg standing time with eyes open, and sit-and-reach distance) and cognitive function (Mini-Mental State Examination and Trail making test-Part A [TMT-A]). The results showed moderate or higher significant correlations of usual gait speed with knee extension strength (r=0.51) and the TMT­A (r=­0.52). Maximum gait speed was correlated with knee extension strength (r=0.74), TMT-A score (r=­0.66), and one-leg standing time with eyes open value (r=0.56) in the pre-sarcopenia group. In contrast, in the normal muscle mass group, no moderate or higher significant correlations between gait speed and any of the items were observed. These findings indicated that elderly individuals with pre-sarcopenia may walk with a higher level of exertion than those with normal muscle mass; this finding implies that a slight decrease in leg strength, balance ability, or attention function may trigger a decrease in walking ability of elderly individuals with pre-sarcopenia.</p>
