過去的研究顯示，骨折術後早期自主運動能有效降低組織沾黏，但病人常因為手術後的疼痛及對術後限制的不了解，僅用藥物達到良好的疼痛控制，而複雜的復健動作只能在治療師有限的介入下才能實施，造成病人平時缺乏互動的回饋，而無法達到自主運動的目地，錯過復健的時機。此外在評估病人的活動量，通常經由醫護人員臨床訪視詢問照顧者，以整理病人的自我報告所獲得，因口頭敘述較為主觀，對於病人的活動量及動作品質難以量化，可能導致彙整的結果無法進行比較或參考，成為現行醫療體系中記錄上的盲點。本研究目的在於結合無線感測器技術以及動畫技術，對於髖關節、膝關節與踝關節，開發下肢骨折術後引導式互動復健訓練系統，並建立動作分析方法(Motion Analysis)以及運動表現評估方法，提供醫療照顧人員客觀的評估，在簡單方便的紀錄工具下，可以瞭解病人的復健狀況。並透過互動回饋(Interactive Feedback)的設計，嘗試改善術後復建的方式，增加參與者自我健康管理的興趣，以利持續追蹤復健資訊。本系統經由醫學實證顯示，引導式復健系統能夠增進病患投入復健訓練的動機及意願，也能夠提升訓練過程之運動活動的「質」與「量」。Prior studies show that self-motions early after a fracture surgery can effectively reduce the tissue viscosity. However, due to the postoperative pain and unawareness of the postoperative limitations, a patient prefers to take medication to alleviate pain while complicated rehabilitation exercises can only be implemented under the limited intervention of a therapist, resulting in the patient's lack of interactive feedback on a daily basis and a failure of self-motions to miss the timing of rehabilitation. Additionally, an assessment for the patient's amount of movements is usually carried out by questioning a caregiver by the medical staff during a clinical interview to organize the patient's self-report because an oral statement is more subjective and difficult to quantify the patient's amount and quality of movements, which may lead to the compiling results that can not be compared or referenced to, and may become a blind spot in the record in the current health care system. This study is intended to develop a lower limb fracture postoperative-guided interactive rehabilitation training system for the hip, knee and ankle joints, and establish a method of motion analysis and a method of motion performance assessment in conjunction with the wireless sensor technology and animation techniques, providing an objective assessment from the caregiver and learning the patient's rehabilitation status with a simple and easy recording means. Additionally, with the design of interactive feedback, the improved postoperative rehabilitations are tried to increase the participant’s interest in self-management of health and facilitate to keep tracking the rehabilitation information. The medical evidences show that a guided rehabilitation system can enhance the patient's motive and willingness to be committed to a rehabilitation training as well as increase Quality and Amount of the exercise activity during the training process.
