目的:本研究旨在針對罕見皮肌炎患者的動作與生活功能，透過以職能為基礎，結合低強度任務導向型的介入模式，並融合「個案為中心」、「任務導向訓練」及「以職能為方法」三大介入原則的治療成效。方法:本研究由具備合格執業執照的職能治療師，在研究進行之醫療院所執行所有的評估與介入流程。我們在治療前與治療後，以肌力量表評估個案上肢與下肢肌力，並以巴氏量表評估日常生活功能。個案接受每次 30 分鐘、每週 5 次、為期 2 週，共 10 天的治療。結果:巴氏量表與肌力量表的評估結果於前後測表現並無差異。然而，個案在軀幹控制能力，以及部分基本日常生活功能可觀察到微幅的進步。結論:本個案報告的初步研究結果，有助於未來逐步建構對於皮肌炎患者的實證職能治療介入模式。未來我們須要透過進一步的實驗設計證實本個案報告所觀察到的現象。

Objective: The purpose of this study was to examine the effects of occupation-based intervention combined with low-intensity task-oriented training incorporating the tenets of client- centeredness, task-oriented training, and occupation-as-means to intervention for patients with dermatomyositis. Methods: All assessments and intervention sessions were conducted by a licensed occupational therapist at the study site. Results: The intervention consisted of 10 treatment sessions. There were no differences from the pre- to post-intervention on the Barthel Index (BI) and the MRC score. However, there was a trend for improvement in trunk control and certain basic activities of daily living. Conclusion: This research paved the way to evidence-based interventions in occupational therapy for patients with dermatomyositis. Future research based on a group-design study is needed to validate the findings of this case study.
