社區高齡者於直線、橢圓形走道與跑步機上執行六分鐘行走測試距離的差異

Differences on The Distance of Six-minute Walk Test on A Line, An Oval Track, or A Treadmill in Community-Dwelling Older Adults

指導教授 : 許妙如

摘要


背景與目的:六分鐘行走測試已被證實可用於測試高齡者功能性能力,臨床上常以方便取得的空間做六分鐘行走測試,但不同走道對高齡者行走測試距離影響還需要進一步探討。因此本研究主要目的為探討高齡者在直線走道、橢圓形走道和跑步機上測量六分鐘行走測試距離的差異。次要目的為:一、建立高齡者分別於三種測試環境執行六分鐘行走測試之預測公式;二、建立高齡者三種不同測試環境所得距離之互換公式;三、探討生理層面(下肢肌力、平衡),以及心理層面(運動動機、自覺表現能力)對於此三種不同測試環境下所測得之距離的差異相關性。 方法:本研究採橫斷式設計,共61位社區高齡者參與研究,每位受試者隨機執行三種測試環境之行走測試。測量參數包含行走距離、老年人身體活動量表、運動行為調節問卷、自覺完成能力、下肢肌力及柏格氏平衡量表,以及每次行走測試前後之心率、血壓、自覺用力係數。其中有41位在不同天進行第二次三種走道之六分鐘行走測試,以比較學習效應。 統計:所得資料先以描述性統計分析,並依據資料分布情形進行母數或無母數分析,統計顯著水準為0.05。以皮爾森相關係數分析不同種走道間距離與各變數的相關性,並以多元及單元迴歸分析分別建立各測試走道六分鐘行走測試距離的預測公式及兩兩互換公式。 結果:直線走道比在橢圓形走道及跑步機上的六分鐘行走測試距離遠,橢圓形走道顯著比在跑步機上的行走測試距離遠,且皆有統計上的差異。第二次三種走道的六分鐘行走測試距離皆增加且有統計上的差異。六分鐘行走測試距離與受試者的柏格平衡量表得分和下肢膝伸直、膝彎曲和踝蹠屈肌力、行走測試後心率及收縮壓顯著相關,但不同走道上六分鐘行走測試距離與老年人身體活動量得分、運動行為調節問卷得分、自覺完成能力和自覺用力係數沒有統計上的相關。本研究結果建立的直線、橢圓及跑步機迴歸公式預測力分別為0.33、0.25、0.36。 結論:本研究顯示不同走道間六分鐘行走測試距離具有相關性,但跑步機上測試距離最短,臨床上使用不建議直接與直線測試結果相比較。

Background and Purpose: Six-minute walk test (6MWT) has been considered as a functional capacity test for the older people. Due to the limitation of clinical environments, 6MWT is often executed over modified test walkways. Whether the test results of 6MWT over different walkways are the same is not fully explored. Therefore, the main purpose of this study was to explore the differences on the distance of 6MWT over a line, an oval track, or a treadmill in community-dwelling older adults. Secondary purposes were: 1) to establish the prediction equations of walking distance for 6MWT (6MWD) over those three walkways and the conversion equations between any two of the three 6MWD; 2) to explore the correlation of physiological (lower extremity muscle strength and balance) and psychological (motivation and self-perceived performance ability) parameters with the distance for each of 3 different walkways. Methods: A cross-sectional design was used. Sixty-one community older adults over 65 years were included. Each subject randomly received 6MWT over a line, an oval track, and a treadmill. Outcome measures included the 6MWD, the Chinese version of the physical activity scale for the elderly ( PASE-C), lower extremity muscle strength, berg balance scale (BBS), self-perceived performance ability, and before/after heart rate (HR), blood pressure (BP), and Borg's rating of perceived exertion scale (RPE). Forty-one subjects completed an additional 6MWT over the 3 walkways on a separate day to compare the learning effect. Statistics: All data were analyzed with descriptive statistical analyses. Data were examined with normality tests and parametric or nonparametric statistical analyses were used accordingly. The Pearson correlation analysis was employed to examine the correlation between three 6MWDs and physiological and psychological parameters. Multiple regression and simple linear regression analyses were used to establish prediction equations for each 6MWD and the conversion equations between any two of the 6MWDs, respectively. Results: The distance from 6MWT for the line walkway was farthest, followed by the oval walkway and then the treadmill. The second 6MWD for each of the three walkways was significantly farther. BBS, the muscle strength of knee extensors, knee flexors and ankle plantarflexors, systolic BP and HR after 6MWT had correlations with the 6MWD of the 3 walkways. No correlation between 6MWD and PASE-C, BREQ-2, self-perceived performance ability, and RPE were found. The percentage of 6MWD for the line, oval track, and treadmill explained by the predictors were 0.33, 0.25, and 0.36, respectively. Conclusions: Any two of the 6MWDs of 3 walkways are correlated with each other, but the treadmill 6MWD the least. It is inappropriate to consider the treadmill 6MWD as the same as the line 6MWD.
