中風病患姿勢控制評估量表及柏格氏平衡量表使用於可行走的慢性中風病患之比較

Comparison of the postural assessment scale for stroke and the berg balance scale among ambulatory patients with chronic stroke

臨床上中風病患姿勢控制評估量表及柏格氏平衡量表常被使用於評估中風病患的平衡功能，柏格氏平衡量表因為地板效應，並不適合用來評估急性中風或嚴重失能的中風病患。本研究聚焦於可行走的慢性中風病人，共收案23人，發現中風病患姿勢控制評估量表及柏格氏平衡量表之間具有統計學上的高度相關（斯皮爾曼等級相關係數為.93, P<0.05），但因中風病患姿勢控制評估量表更為全面並且施作更省時，對可行走的慢性中風病人是更好的選擇。另外我們也發現中風病患姿勢控制評估量表的動態項目與拿掉閉眼行走項目的柏格氏平衡量表之間具有更高度相關（斯皮爾曼等級相關係數為.99, P<0.05），是否能取代柏格氏平衡量表作為中風的預後因子需要未來更多的研究。

 

Background and purpose: We examined the correlation between the scores of the Postural Assessment Scale for Stroke Patients (PASS) and those of the Berg Balance Scale (BBS) among ambulatory patients with chronic stroke. If the PASS scores are strongly correlated with the BBS scores, the PASS would be a superior alternative for evaluation because it can be administered faster and is more comprehensive. Methods: The PASS and BBS scores of 23 independently ambulatory patients with chronic stroke were collected and analyzed using Spearman’s rank correlation. Because the BBS includes more items for assessing dynamic balance function, we also analyzed the correlation between the scores of the changing posture subscale of the PASS and the scores of the BBS. Results: The Spearman rank correlation coefficient (r) between the BBS and PASS scores was .93 (P<0.05), that between the changing posture scores and BBS scores was .87 (P <0.05). Conclusions: Our study indicated that among ambulatory patients with stroke, the PASS and BBS scores were strongly correlated. Thus, the PASS is a superior alternative for evaluating patients with stroke because it is faster to administer and more comprehensive. Contrary to our hy-pothesis, the degree of the correlation between the changing posture scores and the BBS scores was not higher than that of the correlation between the PASS and BBS scores. Nev-ertheless, we believe that the PASS is still a more effective test for evaluating balance func-tion among ambulatory patients with stroke.
