片麻痺老人の臥位安静時,坐位安静時および坐位活動時の酸素摂取量比較

Comparison of oxygen consumption among the conditions of quiet lying, quiet chair sitting and chair sitting performing OT activities with the hemiplegic elderly persons

要旨：離床を促し活動性を高める働きかけを酸素摂取の面から捉える目的で，歩行困難な片麻痺老人12人の臥位安静坐位安静および坐位活動時の酸素摂取量を測定した．酸素摂取量は坐位安静の平均3.1ml/min/kgに対し，臥位安静は0.85倍，歌は1.24倍，体操は1.66倍，ボール運動は1.79倍であり，これらの値は体操・ボール運動間を除く全項目間で有意差(p＜0.001)が認められた．以上の結果は健常老人15人とほぼ同様であり，今回対象とした活動では障害の有無や程度にかかわらず同程度の酸素量が摂取されていた．但し低ADL群は高ADL群に比べて呼吸数が多く1回換気量，酸素摂取率が低い傾向があり，活動能力の違いにより酸素摂取の生体反応が異なることが示唆された．

　The purpose of this study was to compare the oxygen consumption measured by the Douglas Bag Method within conditions of quiet lying, quite chair sitting and three kinds of OT activities in chair sitting (singing, physical exercises, playing catch) of the twelve hemiplegic elderly persons who had disabilities in self-walking.

　The mean value of oxygen consumption of each item increased in the order of quiet lying, quiet chair sitting, singing, physical exercises and playing catch. Significant differences were recognized among the oxygen consumption of the five items except between physical exercises and playing catch. The oxygen consumption of each item compared with that of quiet sitting were 0. 85 times for quiet sitting, 1. 24 times for singing, 1. 66 times for physical exercises and 1. 79 times for playing catch. There were not significant differences, except in the case of physical exercises, between the result of twelve hemiplegic elderly persons and the result of fifteen able bodied elderly persons.

　But in the group of low Barthel Index, the result showed a low ventilation volume and a low ratio of oxygen consumption and a high number of respiration. It was suggested that the responces for the oxygen consumption were different according to their ability for activities of daily living.
