五十肩又稱冰凍肩，是臨床上常見的肩部疾病，一旦肩關節受傷則許多日常生活功能就會受到限制，但是由於傳統治療過程枯燥乏味，患者往往無法持續完成整個療程，因此影響復健的效果。隨著科技的進步發達，眾多新興科技，例如：虛擬實境技術、互動技術、遊戲技術..等，日漸純熟且普及，有許多的研究結合新式科技技術與醫療復建，進行新型復健系統的開發。
本研究將針對冰凍肩患者的復健運動，包括屈曲、外展、內轉、外轉、環狀(繞圈) 等運動，結合虛擬實境技術及互動技術開發肩關節復健系統，模擬生活情境並設計以任務為導向的的訓練任務，同時也設計各式感知刺激(視覺、聽覺)以提升使用者沉浸度，並運用被動式力量反饋模式提供病患真實力量刺激，更設計一系列各式難易度之訓練任務，以適應不同損傷程度的病人。
為了探討本系統的復健成效以及患者之科技接受度，並開發新型評估運動指標，本研究設計了臨床試驗並招募四十位五十肩患者參與實驗，在實驗中量測包括臨床評估、任務表現、運動軌跡歷程以及使用者問卷等資料。
實驗結果顯示，本系統能夠有效地提升五十肩的復健成效，同時也成功地開發了具有評估功能之新型運動指標，使用者對於本系統有很高的科技接受度，願意持續使用本系痛進行復健。

Frozen shoulder is a common clinical disease. If a shoulder is injured, many everyday functions will be limited. Because of boring traditional treatment, patients are often unable to continue to complete the entire course of treatment it affects the result of rehabilitation. With advanced technology, many new technologies, such as: virtual reality technology, interactive technology, games technology etc., increasingly skilled and popularity, there are many studies combined with modern technology and medical rehabilitation science and technology for the development of new rehabilitation system.
This study will focus on patients’ frozen shoulder rehabilitation exercises, including flexion, abduction, internal rotation, external rotation, and circling sports combined with virtual reality technology and interactive technology development shoulder rehabilitation system.
It simulates life situational and task-oriented design of the training mission, while also designed to stimulate all kinds of perception (vision, hearing) to enhance the user immerse degrees, and the use of passive force feedback mode provides patients with true strength exciting, and more
kinds of difficulty choose of the training mission, to adapt to different degree of injury to the patient.
In order to investigate the effectiveness of the system of
rehabilitation and patient acceptance of the technology and the development of new assessment exercise index, this study was designed clinical trials and recruited forty patients with frozen shoulder participate in the experiment, measured in the experiment, including clinical assessment, task performance, sports track process and user questionnaires and other information.
Experimental results show that the system can effectively enhance the effectiveness of frozen shoulder rehabilitation, but also successfully developed a new type of movement indicator assessment function, the user for this system has a high degree of technology acceptance, willing to continue to use this system for pain rehabilitation.
