背景和目的：米勒費雪症候群是格林—巴利症候群的變異型態。臨床上常見的症狀有喪失深部肌腱反射、 共濟失調、眼肌麻痺。在物理治療臨床經驗上是非常有限的。本篇研究目的在呈現一位米勒費雪症候群的患者， 執行個別化運動訓練後的效果。方法：一位77 歲男性有軀幹共濟失調，意向動作震顫，缺少深部肌腱反射及 延髓麻痺，被醫生診斷為米勒費雪症候群。我們使用柏格式平衡分數量表、修改版國際協調共濟失能評估量表 和功能獨立量表來評估平衡、共濟失調及日常功能；運動訓練包括動態站姿平衡訓練、協調訓練及功能訓練， 最後我們記錄運動訓練前後的生理評估測試。結果：利用國際健康功能與身心障礙分類系統分析個案問題，發 現有軀幹共濟失調、站姿平衡不足及步態不穩等問題。在6 週的個別化運動訓練後，不論是修改版國際協調共 濟失能評估量表、柏格式平衡分數量表及功能獨立量表分數均有進步。結論：米勒費雪症候群患者接受6 週個 別化物理治療訓練後可以改善其行走能力、平衡及減少共濟失調。

Background and Purpose: Miller Fisher syndrome is a variant Guillain-Barré syndrome, and is clinically defi ned by a triad of symptoms, namely: arefl exia, ataxia, and ophthalmoparesis. It is rare and lack of clinical evidence to support physical therapy intervention. Th e purpose of this study is to present the eff ect of individual exercise training program in a patient with Miller Fisher syndrome. Methods: A 77-year-old man presented with trunk ataxia, intentional tremor, absent deep tendon refl ex, and bulbar palsy was referred to physical therapy department. Miller Fisher syndrome was diagnosed after serial examinations. We used Berg balance scale (BBS), Modified International Cooperative Ataxia Rating Scale (MICARS) and Functional Independence Measure (FIM) to assess the balance, ataxia and functional ability. Training program included dynamic standing balance training, coordination training, and functional ability training. We recorded the data of physical examination before and after exercise training. Results: With the analysis of international classifi cation of functioning, disability, and health model, we found the main problems included trunk ataxia, insuffi cient standing balance and unsteady gait. After 6 weeks of individual training program, MICARS, BBS and FIM scale were improved. Conclusions: Patients with Miller Fisher syndrome could improve their walking ability, balance and reduce ataxia after six weeks of individualized physical therapy training.
