At the same time,the number of stroke patients raises annually. The mortality rate of stroke is very high. Though some survive,most of them will surfer varying degrees of paralysis sequel. Modern robotics technology is introduced for those patients with paralysis sequel. During their rehabilitation,modern robotics technology plays a very great role and improves efficiency greatly. This subject mainly studies the designing of hardware circuit for a finger rehabilitation system. In the beginning, this paper introduces the current research status and trend of the finger rehabilitation system. According to the analysis of recent researches in the field of finger rehabilitation,MagoRheological Damper in force feedback is introduced in the rehabilitation system. Based on the phases and demands of finger rehabilitation,this paper has investigated passive force feedback mechanism and achieved force feedback control method for a hybrid of active amp。 passive circuit of the finger rehabilitation system contains data acquisition module,dive control module,munication debugging and interface modules and power conversion and management modules. On the basis of rational schematic design and bining circuit simulation,the feasibility of the circuit gets guaranteed. Keywords: finger rehabilitation。 MagoRheological Damper。 control system。 hardware circuit designing 4 第一章 緒論 腦卒中又稱腦血管意外, 因為突發(fā)性的或者腦血管病變從而引起腦功能障礙,并且持續(xù)二十四小時以上或者直接導致死亡的癥候群。每年腦卒中的發(fā)病率為 200/100 萬, 存活者中約 75% 致殘, 40% 的患者留下功能障礙, 15% ~ 30%的患者留下重度殘疾 [1]。臨床以昏仆,口舌歪斜,失語,偏身麻木,半身不遂等癥狀,其中肢體功能障礙為主要致殘原因。 腦中卒發(fā)病迅速,變化快,一般是是老年人容易患上中風。腦中卒患者如果得以幸存,往往會留下后遺癥,一些語言或者肢體的障礙會給患 者自我的生活帶來極大的不便。隨著人們生活水平的不斷提高,一些人的生活作息不規(guī)律,飲食不健康,長期缺乏適當運動,人體的生理
