摘要

目的：本研究目的為依據國際功能、障礙和健康分類模式，分析機構失智症老人身體功能評估項目中，三公尺計時起走測驗的相關因子，以及5周後三公尺計時起走測驗改變量之預測因子。方法：本研究探病歷回顧方式，收集台北市至善老人安養護中心失智區內，失智症老人之常規物理治療評估結果。針對計時起走測驗表現、5周內改變量，選擇身體功能構造、活動與參與等評估結果，加入年齡等個人因素，進行多變數迴歸分析。結果：共收集17位失智症老人之評估結果，平均年齡為80.65±6.22歲，簡易智能狀態測驗分數平均14.12±5.06分。5周內計時起走測員會改變量平均為4.91秒(p=0.01)，達顯著進步。多變數迴歸分析結果，行走速度和30秒坐到站為計時起走測驗的相關因子(R^2=0.65, p=0.001)。但在計時起走測驗改變量之預測模式中，未找到統計上顯著之預測因子。結論：國際功能、障礙和健康分類中活動與參與層級的行走速度及身體功能與構造層級的30秒坐到站為機構失智症老人計時起走測驗能力之相關因子。本研究中未找到計時起走測驗改變量之預測因子，未來研究可加入環境因素及不同嚴重度之失智症患者進行大型實驗。

Purpose: The purpose of this study was to evaluate the associated factors of Timed Up and Go test (TUGT) and predictors of 5 weeks change of TUGT for institutionalized seniors with dementia. Classification of assessment items was based on International Classification of Function, Disability and Health. Methods: This study used retrospective chart review, collecting physical therapy assessment record of seniors with dementia from a long term care facility in Taipei, Taiwan. Pearson's correlation coefficient was used to find the possible factors of TUGT Multivariate regression analyses were performed to identify factors associated with TUGT performance and 5 weeks change of TUGT. Results: A total of 17 assessment records of seniors with dementia were included (averaged age 80.65±6.22 years, MMSE 14.12±5.06). There was significant progress of TUGT in 5 weeks (4.91 seconds, p=0.01). Multivariate regression analysis identified walking speed and 30-s chair-stand test as associated factors of TUGT (R^2=0.65, p=0.001). However, no predictors were found in the predictive model of 5 weeks change of TUGT. Conclusion: Walking speed and 30-s chair-stand test are associated with TUGT in institutionalized seniors with dementia. This study did not find any significant predictors for 5 weeks change of TUGT. Future studies may include environmental factors and severity of dementia as potential associated or predicting factors.
