腦血管疾病俗稱中風或腦中風，在十大死因中排名第三，研究顯示糖尿病、高血壓抽菸是中風的主要因子之一，根據衛福部2007年的研究，高血壓及高血糖的盛行率隨著年齡呈顯著上升的趨勢，而隨著人口結構的改變，台灣將在2018年將邁入高齡社會，更將於2025年邁入超高齡社會，由以上因素可推論台灣社會將面臨嚴苛的中風及中風後的復健需求，並將成為醫療上的重大負擔。有許多學者提出早期的被動運動以及在患肢軟弱無力(flaccid)的階段提供肩部的保護、支撐，可以減少HSP或軟組織攣縮的風險，但一般復健運動需要復健師的全程參與，對復健師是一大工作負擔。本研究所發展之復健輔具以充氣及強制洩氣的方式，透過氣囊進行手臂外展、內收的被動運動。輔具有一充氣背心(以魔鬼氈做穿戴，可穿戴於左手或右手)及控制箱，控制箱上有三個模式按 - ModeⅠ/Ⅱ/Ⅲ，患者僅需穿戴充背心並按下欲執行之模式，輔具便會啟動，幫助患者執行手臂之被動運動。在系統的穩定性實驗中，本復健輔具在0 ~ 3公斤的外力測試下，抬升角度誤差皆在三度以內，顯示本系統穩定性高，適用於不同體態之中風患者。在氣囊之壓力與外力(0 ~2 kg)的實驗中，我們發現外力與氣囊壓力的變化量呈正相關，因此若為同一復健患者，在短時間之復健過程中，若所量測到的氣囊I之壓力呈穩態上升，可推論為復健患者出現肌肉張力變大的狀況，並採取必要措施。由實驗的測試結果證實，本研究所發展之充氣式肩關節復健輔具，具低成本、方便使用之特性，是一適合中風後居家執行手臂外展、內收被動運動之工具之一。

Cerebrovascular disease is commonly known as stroke and has been ranked as third in 10 Leading Causes of Death in Taiwan in 2013. Some researches mention that the major factors of stroke include diabetes, hypertension, and smoking. Furthermore, diabetes and hypertension have been ranked fifth and eighth in the 10 Leading Causes of Death respectively in Taiwan. According to the Ministry of Health and Welfare in 2007, the prevalence of hypertension and hyperglycemia are increasing with age. The changes in age composition of the Taiwan population would become an aged society by 2018 and a “hyper-aged” society by 2025. From the above factors it can be inferred that Taiwan society will encounter a severe issue of stroke and after stroke rehabilitation needs and increasing burden of healthcare. Many studies have been proposed early passive movement and providing the support and protection in the flaccid stage can prevent immobility, soft tissue contracture and minimize the risk of HSP. Rehabilitations are heavy burden of physical therapists due to a one-on-one interaction with patient has been required. The purpose of our study is to develop a low cost and portable rehabilitation device for patients to rehab at home. Home-based rehabilitation not only increases the convenience, but also reduces the cost of rehabilitations and the burden of physical therapists. The rehabilitation device we developed is conducting the shoulder abduction and adduction by inflating and deflating the airbags of device. The device includes one inflatable vest (using Velcro to fix the vest on body, and is suitable for both side of arm) and one control box. The control box has three mode buttons - ModeⅠ/Ⅱ/Ⅲ. Patient only needs to wear the inflatable vest and press the mode button which was advised by the physical therapist. Then the rehabilitation device will aid patients to complete the passive movement. The results of system stability test showed that the lifting angle variation of our device under different external force (0 ~ 3 kg) was below three degrees. It appears that our device has good suitability for users with wide range of body weights. The positive correlation between external force (0 ~2 kg) and the pressure in airbag have been found by loading vs. airbag pressure experiment. If the same patient’s pressure in airbag is steady rising during rehabilitation course, a close attention should be paid to the muscle tension increasing. Our shoulder rehabilitation device is one of the cost effective and user friendly devices for stroke patients to conduct the passive movement at home.
