脊髓損傷患者之功能性電刺激踩車系統

在各種復健的方法中，功能性電刺激最早是被利用來治療中風患者，後來才漸漸地被推廣至脊髓損傷患者的復健治療上。目前，功能性電刺激在脊髓損傷患者上主要是應用在肌力訓練、踩車、站立及行走。在這四者之中，功能性電刺激踩車運動有著設備較簡單，設計容易及安全性高等優點。目前市面上功能性電刺激踩車系統的商業化産品中，是以兩家美國的公司爲主，但是價格昂貴。本文主要是報告一位脊髓損傷患者使用一套由國立成功大學醫工所研發出的功能性電刺激踩車系統的測試結果，希望在國內能有價格更大眾化，使用更方便的系統使得此種復健治療方式更爲普及。使用及測試結果顯示，此系統訓練的模式及刺激的組態可事先設計在電腦程式中，在操作上非常簡便。最重要的是，在低速定速、速度漸增、速度先增後减及高速定速四種運動下，刺激的電流量都能有效的調整，同時病患可以達到平順的踩車運動。然此系統由於沒有阻力的裝置，因此運動的訓練量很低，未來應朝向將阻力裝置與原系統整合，才能利用功能性電刺激踩車運動來做爲下半身癱瘓患者的復健方式。

Functional electrical stimulation (FES) was first applied for rehabilitation of stroke patients, and then to spinal cord injured (SCI) patients. FES were mainly used for muscle strengthening, cycling, standing and ambulation training in SCI. Among these four training, FES cycling exercise has the advantage of safe, efficient, and easy execution over other three. There are two American company manufacture commercialized FES cycling system, but both of them are very expensive. This paper aimed to report the application of a FES cycling system which was designed by Graduate Institute of Biomedical Engineering, National Cheng Kung University. It is our hope that soon SCI patients here can have access to this system for their therapy. According to the result of testing, all the stimulation pattern arid training protocol can be designed and saved in the computer in advance. This made the operation very easy. There are four exercise protocol including constantly low speed, low to high speed, high to low speed and constantly high speed. Under each of these four conditions, the amplitude of electrical stimulation adjusted itself efficiently and the patient was able to finish the cycling exercise very smoothly. There is no load cell installed in this system, and the currently exercise intensity is not sufficient to challenge the cardiopulmonary system. Future development should add load control to this system to improve its function.
