Some studies have indicated that functional exercise training, known as the task-oriented exercise, improved cerebral blood flow. However, the effects of task-oriented aerobic exercise training on chronic stroke patients were unknown. The study was designed to investigate the effects of task-oriented aerobic exercise training on cardiorespiratory fitness, functional performance, physical activity, cerebral blood flow in patients with chronic stroke, and the association between the changes of measured outcomes. Methods: Patients with chronic ischemic stroke (post-stroke duration > 6 months) were recruited and assigned to exercise intervention group or control group by the stratified randomization according to the gender and severity of stroke. The intervention group underwent task-oriented aerobic exercise training for 12 weeks, while control group was asked to maintain regular physical activities by weekly telephone checks. Outcome measures included variables in a symptom-limited exercise test, 6-minute walk distance, selective walking speed from a 10-meter walk test, Rivermead mobility index (RMI), instrumental activity of daily living scale (IADL), physical activity scales for individuals with physical disabilities (PASIPD) and Doppler measurements before and after 12 weeks. All statistical analyses were performed by SPSS 11.5 (SPSS Inc., Chicago, USA). A two-tailed p value less than 0.05 were considered statistically significant. Independent t test and chi-square test were used to compare baseline data between two groups. A mixed model ANOVA was used to compare the exercise capacity, functional performance and physical activity between groups across time. A 2×2 two-way ANCOVA was performed to analyze the cerebral blood flow between two groups with age, gender and resting mean blood pressure as covariates. The relationships between changes of outcomes were analyzed by partial correlation coefficient. Results: There were no significant group differences in baseline data except comorbidity and respiratory exchange ratio derived from the exercise test. Significant interaction was noted in variables of peak oxygen consumption, peak oxygen pulse, peak minute ventilation, 6 minute walk test, selective walking speed and mean blood flow velocity of anterior cerebral artery in non-affected hemisphere. In addition, participants in exercise group showed significant time main effect without interaction in RMI, PASIPD, mean flow velocity and flow volume of internal carotid artery in non-affected hemisphere, and total flow volume of extracrainial arteries in non-affected hemisphere after 12 weeks. The change of selective walking speed moderately correlated with the change of IADL (r=0.469), PASIPD (r=0.676), peak oxygen consumption (r=0.503), peak oxygen pulse (r=0.573), and peak minute ventilation (r=0.649). Moreover, the change of peak workload and the change of mean flow velocity of anterior cerebral artery in affected hemisphere showed moderate negative correlation as well (r=-0.800). Conclusion: Task-oriented aerobic exercise training improved cardiorespiratory fitness, ambulatory capacity and cerebral blood flow of specific region (territory of anterior cerebral artery in non-affected hemisphere) in our chronic stroke patients. The improvement in cerebral blood flow demonstrated significant correlation with the improvement in cardiorespiratory fitness.第一章、 前言 1 第一節、研究背景 1 第二節、研究目的 3 第三節、研究假說 3 第四節、名詞及操作型定義 3 第五節、研究重要性 5二章、文獻回顧 6 第一節、中風存活者之心肺適能 6 第二節、有氧運動訓練對於中風患者之效果 7 第三節、任務導向有氧運動訓練 8 第四節、腦血流之評估工具 10 第五節、中風患者之腦血流 12 第六節、運動訓練影響腦血流之機制 15三章、研究方法及實驗步驟 18 第一節、研究設計 18 第二節、受試者 18 第三節、實驗步驟 19 第四節、研究工具及方法 19 第五節、運動介入方式 23 第六節、研究變項 23 第七節、資料處理與統計分析 24四章、研究結果 26 第一節、受試者資料 26 第二節、兩組十二週後的參數改變 27 第三節、訓練前後參數改變量之間的相關性 31五章、討論 33 第一節、運動訓練對心肺適能改善之效果 33 第二節、運動訓練對功能評量及身體活動之效果 35 第三節、運動訓練對腦血流參數之影響 38 第四節、不同失能程度分組之探討 39 第五節、各變項改變量相關性之探討 40 第六節、研究限制 41六章、結論 42考文獻 43表目錄1. 中風患者之心肺適能 532. 慢性中風患者之有氧運動訓練研究 543. 受試者人口學資料 564. 慢性中風患者之受傷部位 575. 慢性中風患者最大運動測試結果 586. 慢性中風患者功能評量及身體活動結果 597. 慢性中風患者健側腦半球之血流 608. 慢性中風患者患側腦半球之血流 619. 運動組以失能狀況分組於最大運動測試及功能之表現 6210. 運動組以失能狀況分組於腦血流之表現 6311. 運動組功能評量、身體活動與最大運動測試改變量之相關性分析 6412. 運動組功能評量、身體活動與腦血流改變量之相關性分析 6513. 運動組最大運動測試與腦血流改變量之相關性分析 661. 研究設計流程圖 672. 心肺適能評估收案之狀況 683. 腦血流測量示意圖 694. 受試者收案流程圖 705. 兩組受試者最大攝氧量在前後測之表現 716 .兩組受試者最大氧脈在前後測之表現 717. 兩組受試者最大每分鐘換氣量在前後測之表現 728. 兩組受試者最大呼吸交換速率在前後測之表現 729. 兩組受試者六分鐘行走距離在前後測之表現 7310. 兩組受試者自選行走速度在前後測之表現 7311. 兩組受試者Rivermead移動指數在前後測之表現 7412. 兩組受試者身體活動評量在前後測之表現 7413. 兩組受試者健側前大腦動脈血流速在前後測之表現 7514. 兩組受試者健側內頸動脈血流速在前後測之表現 7515. 兩組受試者健側內頸動脈血流量在前後測之表現 7616. 兩組受試者健側顱外血流總量在前後測之表現 76件目錄件1. 修正Rankin中風等級評量 77件2. 簡易智能狀態測驗 78件3. 受試者同意書 79件4. 受試者資料表 85件5. 美國國家衛生研究院腦中風評估 88件6.
