下背痛是一種疼痛症狀的描述名稱，影響各年齡層的人，是一種非常常見的症狀，大約8成的人在一生中曾因下背痛而抱怨，而以一成不變的治療計畫治療每一位患者，是無法得到成效的，加上傳統復健繁瑣令人覺得枯燥乏味而缺少前來復健的動機。數位科技的進步使虛擬實境技術應用於醫療復健變的可行，加上隨著穿戴式科技日益茁壯，輕巧、準度高、價格低廉的感測器問世，在協助治療師及給予患者動機方面都有很大的助益。 本研究結合虛擬實境技術及IMU無線感測器模組協助治療師與下背痛患者進行三階段的復健運動，三階段分別為：觀察並糾正患者日常生活中因姿勢錯誤而導致背部受傷的動作、由治療師調整適合患者身體狀況的復健目標，患者藉由重複的運動建立全身及關節的穩定度、以金次塔原則增強患者耐力。 共40位下背痛患者參與這次復健計畫，研究以臨床評估、復健表現、使用者問卷探討患者使用系統進行復健之成效與科技接受度，臨床評估在實驗開始前、實驗結束後進行，而復健表現則以第一次和做後一次的數據進行分析。 實驗結果顯示使用系統進行復健的患者在臨床評估上和進行傳統復健的患者相比有較顯著的進步，而在復健表現的部分，每個動作最後一次的結果皆優於第一次復健，此外，使用者對於本系統也有很高的科技接受度，願意持續使用本系統來進行復健。 ;Low back pain affects people of all age, it is a very common health problem worldwide, about 80% of people may have complained about it in their life, and it’s ineffective if we use same treatment to all patient. In addition, rehabilitation therapy takes a long period of time, patient may lacked for motivation or don’t have enough physiotherapists, patients are often unable to finish the entire course of treatment. With the progress in technology and electronic process, makes virtual reality a useful tool in rehabilitation field. Cheaper and more accurate wearable device can also be substitute for motion tracking system in measuring patient’s movement. The system is based on virtual reality and combined wireless sensor which is aim to assist therapist and patient in doing three stages low back pain rehabilitation exercises. The three stages are as follows: Observe and correct patient’s posture which is wrong and will makes them get injury. Therapist adjust proper rehabilitation target for every individual in order to training muscle strength. And in the third stage, the system will set the goal of exercise time and frequency for training endurance. Total of 40 low back pain participate recruited in this study, clinical assessment (include VAS for unpleasantness, VAS for pain and Oswestry Low Back Disability Questionnaire), task performance and user acceptance of technology questionnaires are used to investigate the effectiveness of the system. Experimental result shows that participates using the system for rehabilitation tool have significant improve in clinical assessment compare with traditional therapy group. In task performance, the study group also have great improvement. Finally, the users also have a high degree of technology acceptance and willing to continue to use the system for rehabilitation
