功能性电刺激的原理、设计与应用(二)

Functional Electrical Stimulation: Principle, Design and Applications(Ⅱ)

功能性电刺激（FES）这一技术打开了瘫痪运动功能重建的一个广阔领域。本文分三部分阐述FES的基本概念、设计和应用。第一部分讨论电刺激的阈值，募集顺序等概念，第二部分介绍肌内电刺激的安全参数范围，组织损伤，并讨论刺激器的设计。第三部分以C5／C6患者手功能重建为例，阐明功能性电刺激系统的工作原理。

Functional electrical stimulation(FES) offers a vast potential for partial restoration of parlayzed movements. This three part article will review the basic concepts,system design and applications of FES. In part I,concepts such as activation threshold, recruitment order are discussed. Part Ⅱ introduces stimulation waveforme,safe parameters and tissue damage,as well as the design principle of stimulators for use with percutaneous electrodes. Part Ⅲ outlines clinical applications of FES,in particular,for restoration of hand grasp function for C5/C6 patients.
