The purpose of this study was to investigate body composition focusing on motor functional capacity and to correlate body composition with functional outcomes with subacute stroke patients. The subjects of this study were 34 inpatients with hemiparetic stroke who could walk. Motor functional capacity of patients was assessed on the basis of the Brunnstrom recovery stage (BRS), and functional status was measured using the Functional Independence Measure (FIM) instrument scores and gait velocity. Body composition was assessed by bioelectrical impedance analysis. Significant correlations were observed between FIM scores and the BRS of the lower extremity or lean body mass. The correlations for body water in affected and unaffected legs with the FIM subscores were statistically significant (p

The purpose of this study was to investigate the relationship between daily physical activity and physical fitness in twenty ambulatory post-stroke patients. The pedometric measurement was made using a caloriecounter in daily life at home and assessed to quantify the time constant (τ on) of oxygen uptake (VO2) and oxygen deficit with gas analysis using a bicycle ergometer. There were negative correlations between the amount of daily walking steps and τ on, as well as the oxygen deficit at the onset of exercise (τ on; r=-0.52, p

Hemiparetic stroke patients have both decreased oxygen consumption and low endurance to exercise. This study examined their physical fitness to quantify the initial deficit and change in oxygen uptake kinetics (VO2 kinetics) during inpatients rehabilitation following stroke. Twenty-nine ambulatory hemiparetic stroke patients were treated in an 8-week program of low intensity aerobic exercise. They undertook a bicycle ergometer test with gas analysis before and after the exercise program to obtain maximum oxygen uptake (VO2 peak), maximum work load (max WR), and VO2 kinetics data. The time constant (τon) and O2 deficit on constant load after exercise training were significantly lower than those in initial measurement by 17% and 10%, respectively. On the incremental load, VO2 peak and max WR were significantly increased by 16% and 17% respectively and ΔVO 2/ΔWR was decreased by 11%. These results show that low-intensity endurance training produces energy efficiency of oxygen uptake kinetics and improves the physical fitness of ambulatory hemiparetic stroke patients.

Exercise testing was used to examine 38 type 2 diabetes mellitus (DM) patients without cardiovascular complications, aged 47-74 years (body mass index (BMI), 23.8 ± 1.6 kg/m 2 ), and 18 healthy volunteers, aged 45-68 years (BMI, 22.5 ± 1.5 kg/m 2 ). A graded cycling exercise test was performed, monitoring gas exchange to evaluate physical fitness and exercise endurance by oxygen uptake (V • O2) kinetics. The following results were obtained. (1) Oxygen deficit (O2deficit) and time constant (τ on) at the onset of exercise were significantly higher in subjects with type 2 DM compared with controls (p

今回,我々は呼気ガス分析による運動負荷試験を試行してCVA片麻痺患者の回復期リハビリテーション期における運動耐容能と運動エネルギー効率の改善の有無について検討を行った。対象は,当センターに入院した歩行可能なCVA片麻痺患者29名(男性23名,女性6名,年齢55.7歳)とした。運動麻痺の程度による比較検討するために,下肢のBrunnstrom StageによりIII∼IVの重度障害群とV∼VIの軽度障害群の2群に分類した。入院時と退院時のVO2 peakを比較すると、重度障害群では,有意に改善したのに対して,軽度障害群では改善傾向を示した。また,max WRでは,重度及び軽度障害群で有意に改善した。重度障害群と比較して軽度障害群では,患側下肢を含めた運動遂行能力が高く,早期歩行自立の獲得ができ,末梢運動骨格筋機能の向上による運動エネルギー効率の改善につながったものと考えられる。
