、可量化的跑步機復健運動計劃，對心臟手術病患體能、疲憊感、日常活動的執行與自我效能的影響，希望能藉由 研究確立此心臟復健運動計畫之成效與益處，進而將此心臟復健運動計劃做全面化的推行。

本研究從民國 89 年 10 月到民國 90 年 6 月，共計 9 個月，採立意選樣法，於台北某一教學醫院心臟科病房選取接受 冠狀動脈繞道術術後的開心病患，以跑步機心臟復健運動計劃介入為自變項，因變項包括： 6 分鐘最大行走距離、

疲憊感受與活力知覺得分、日常活動自我效能得分及日常活動進展，分別以 6-minutes walk test 、日常活動進展量 表、日常活動自我效能量表及疲憊問卷量表檢測。追蹤測試的時間分別是出院時及出院後一週與四週。資料分析採 平均數、標準差、百分比、 repeated measurement 、 correlation 、 t test 及 ANOVA 。

研究結果顯示﹙一﹚冠狀動脈繞道術者，術後平均住院天數為 8 天，要達到 4.5mets 的活動量平均是手術後 7.8 天。

﹙二﹚術後平均第 2.72 天完成 1.5mets stage﹙ Ⅰ﹚ 的活動訓練，第 3.88 天完成 2.0mets stage﹙ Ⅱ﹚ 的活動量，第 5.2 4 天完成第一次的跑步機運動訓練﹙ 2.5mets , stageⅢ﹚ ，第 6.25 天完成 3.0mets stage﹙ Ⅳ﹚ 的訓練，第 6.87 天完成 3.7mets stage﹙ Ⅴ﹚ 的訓練，第 7.8 天完成 4.5mets stage﹙ Ⅵ﹚ 的訓練。﹙三﹚各階段運動訓練要達百分之百完成率

，在手術後的日數分別是： stageⅠ 術後第 5 日、 stageⅡ 術後第 6 日、 stageⅢ 術後第 9 日、 stageⅣ 術後第 10 日、

stageⅤ 術後第 9 日、 stageⅥ 術後第 9 日。﹙四﹚影響運動訓練執行的延緩因素有術後肋膜積水、心跳過快、心房 纖維顫動、皮下氣腫、發燒等醫療性因素，與傷口疼痛、頭暈、虛弱。﹙五﹚男性、無糖尿病、氣管內管 24 小時內 拔除者較早進入跑步機的使用階段﹙ stageⅢ﹚ 。﹙六﹚個案出院後 6 分鐘最大步行距離、疲憊感受與自我效能在出 院後一週與出院後四週都有顯著進步。兩階段的進步幅度量並未達統計上顯著差異。﹙七﹚出院到出院後一週與出 院到出院後四週，此二階段的自我效能進步幅度與跑步機首次使用日數成正相關。﹙八﹚出院後之日常活動進展以 爬一層樓﹙ 5.5mets﹚ 為指標，在出院第一週時， 78.38 % 個案完成，到出院第四週時 100 % 個案，可在完全不費 力之下完成該活動。﹙九﹚出院時最高活動 met 數，對出院後 6 分鐘最大步行距離、疲憊感受、活力知覺與自我效 能的進步幅度無影響，但是與出院後一週的自我效能得分呈正相關。

本計畫在執行上是可行的，活動量在出院時最大可達 4.5 mets ，較以往國內的 3.0 或 3.5 mets 活動量，更是接近 美國運動醫學會（ ACSM ）的建議。

The Effectiveness of Inpatient Cardiac Rehabilitation (Treadmill Exercise) Program on Patients with Coronary Artery Bypass Graft



英文摘要



Cardiac rehabilitation program is commonly performed in America and Europe, whereas in Taiwan, it still is in a beginning level. Therefore, the purpo se of this study was to design an aggressive and countable inpatient cardiac rehabilitation （ treadmill exercise ） program for patients with coronary artery bypass graft, and to examine the influences of the program on the physical endurance, performance of ADL, self-efficacy of ADL, and fatigue.

This study was conducted from Oct. 2000 to Aug. 2001. Twenty-fifth subjects who met the selection criteria were selected by purposive sampling fro m a teaching hospital in Taipei. The independent variable was the exercise program and the dependent variables included a maximal distance by using a 6-minute walk test, fatigue, self-efficacy, and the ADL. The data were collected at the 1st week and 4th week after discharge from hospital by the 6- minute walk test, the Fatigue/Stamina scale, the Activity Self-Efficacy scale and the Duke Activity Index. Data was analyzed by percentage, mean, sta ndard deviation, t test, one-way ANOVA, correlation, and repeated measurement.

The major finding of this study were as follows ：

1. The average time in hospital was 8 days after CABG. It took 7.8 days after operation to complte the stage Ⅵ （ 4.5 METs ） of the program.

2. The average days for completing each stage was 2.72 days （ stage , 1.5 METs Ⅰ ） , 3.88 days （ stage , 2.0 METs Ⅱ ） , 5.24 days （ stage , 2 Ⅲ .5 METs, as first treadmill’s using ） , 6.25 days （ stage , 3.0 METs Ⅳ ） , 6.87 days （ stage , 3.7 METs Ⅴ ） , and 7.8 days （ stage , 4.5 MET Ⅵ s ） .

3. Patients in every stage of training achieved 100 completion, the average day of completion was stage at 5th day after operation, stage at 6th ﹪ Ⅰ Ⅱ day after operation, stage at 9th day after operation, stage at 10th day after operation, stage at 9th day after operation, stage at 9th day after o Ⅲ Ⅳ Ⅴ Ⅵ peration.

4. The major reasons for prolonging the progression of exercise training were plural effusion, tachycardia, atrial fibrillation, subcutaneous emphysema, fever, chest wall’s wound pain, dizziness, and weakness.

5. The thired stage of the program was started early in patients who are male, non-diabetes and the endotracheal tube removed in 24 hours after operati on. 6. After discharge, the maximal walking distance, self-efficacy, fatigue and stamina were significantly improved at the 1st week and 4th week after dis charge from the hospital.

7. From discharge to after discharge 1st week and from after discharge 1st week to 4th week, these two section increased percentages of the self-effica cy scores with the first treadmill’s use shows a significant positive correlation.

8. One week after discharge from hospital, 78.38 of patients may perform 5.5 METs ADL. Four weeks after discharge from hospital, 100 of patie ﹪ ﹪ nts may perform the same level of ADL without complaint.

9. The maximal performed at discharge was significantly correlated with the self-efficacy scores at the 1st week after discharge.

It was concluded that the patients who undergone the inpatient cardiac rehabilitation （ treadmill exercise ） program can perform higher intensity in

daily activities than the patients who received the general inpatient cardiac rehabilitation programs.
