脳卒中片麻痺患者の歩行時酸素摂取量

Abstract

The relations between oxygen uptake and Brunnstrom's recovery stage, speed of walking, age and sex were investigated in nineteen hemiparetic patients. Nine of them were males and ten were females. Their mean age was 59.3. There were thirteen cases of cerebral hemorrhage and six of cerebral infarction. Oxygen uptake was determined by analysis of expired gas collected in a Douglas bag during walking. The mean of oxygen uptake was 12.85±4.14(S.D.) mlO_2/kg/min. There were no significant relationships between oxygen uptake and Brunnstrom's recovery stage, speed of walking or age. However, oxygen uptake in females was significantly less than in males. We speculated that males walked with more effort than females and found that several patients required more oxygen than normal subjects in unrestrained walking.
