The Effects of Exercise Training on Walking Functi on and Percetion of Health Status in Elderly Patien

運動訓練對老年周邊動脈阻塞患者行走功能 與自覺健康狀態成效之探討



本研究採類實驗設計法選取台北市北區某醫學中心，經由心臟血管外科專科醫師轉介周 邊動脈阻塞病患為研究對象，依隨機方式將個案分為運動組及對照組，共有 22 位個案 完成此研究，其中運動組 10 人，對照組 12 人。運動組參與為期八週的跑步機運動訓練

，對照組則保持其原本生活方式，八週前後經結構式問卷、六分鐘行走測試與跑步機運 動測試進行資料收集。資料分析採百分比、平均值、標準差、 Spearman correction 、 M ann-Whitney U test 、 及 Wilcoxon Sign-Rank test ，以探討跑步機運動訓練對周邊動脈 阻塞病患對其自覺、實際行走功能與自覺健康狀態之成效。

研究結果發現：（一）周邊動脈阻塞病患在自覺健康狀態中得分屬於中等，身體功能層 面得分較心理功能層面得分低。（二）基本屬性與病患自覺健康狀態並無顯著相關，年 齡與病患實際六分鐘行走距離呈現負相關，收縮壓對於病患自覺行走距離亦呈現負相關。

（三）運動訓練後，病患在自覺健康狀態中身體功能層面增加 50% ，較心理功能層面 增加來的顯著，各次概念增加程度則由 20% 至 178% 。（四）運動訓練後，病患自覺 行走功能有顯著的改善，改善程度由 17%-36% 。（五）運動訓練後，病患在實際行走 功能有顯著的改善，其改善情形達 168.9%-187.5% 。

本研究結果顯示周邊動脈阻塞病患因行走功能受限，影響其自覺健康狀態，在經過八週 的跑步機運動訓練後，對於周邊動脈阻塞病患在自覺行走功能、實際行走功能與自覺健 康狀態皆達到顯著的成效。

The Effects of Exercise Training on Walking Functi on and Percetion of Health Status in Elderly Patien

ts with Peripheral Arterial Occlusive Disease



There are great impact on the walking function and perception of health status due to limited arterial blood supply to lower extremities and intermittent claudication among patients with peripheral arterial occlusive disease. However, studies regarding the effects of exercise training on the patients'' walking f unction and perception of health status are very rare in Taiwan. The purpose of this study is to explore the effects of exercise training on the walking function and perception of health status in elderly patients with peripheral arterial occlusive disease.

A quasi-experimental design was used to guide the study. Subjects who met the criteria were referred by a cardiovascular surgeon at a medical center in Taipei. Twenty two patients enrolled in our study who were r andomly assigned into either exercise or conrtrol group. The exercise group was assigned to join an 8-week treadmill exercise program. The control group remained their living pattern. Data were collected by the str uctural questionnaires, 6-minute walking test and treadmill exercise test. Percentage, mean, standard deviat ion, Spearman correlation, Mann-Whitney U test and Wilcoxon Sign-Rank test were used for the data anal ysis.

Research results were shown as follows: （ 1 ） Patients perceived moderate degree of health status and reported lower scores in physical function dimension than in psychological dimension. （ 2 ） Age was negatively correlated with 6-minute walking distance. Systolic blood pressure was negatively correlated wi th perceived walking function. （ 3 ） The perception of health status of patients was improved by 20%~

178% after exercise training program. The physical function dimension of perceived of health status impro ved more significant than the psychological dimension. （ 4 ） Patients perceived better of walking func tion by 17%~36% after exercise training program. （ 5 ） The actual walking function by 168.9% to 157 .5% of the patients was increased after exercise training.

Based on the results of this study, it was concluded that there was a great impact on patients''

perception of health status due to their limited walking function. After paticipating in an 8-week treadmill

exercise training program, the patients indeed improved their perception of health status and walking functi

on.
