対麻痺の起立歩行再建を目的とした膝関節ロック機構連動式FESシステムの開発

本研究的目的是研制一种与膝关节支架相结合的混合式功能电刺激系统，该系统具有电锁定机构，用于截瘫患者的站立和行走。(1)混合式功能电刺激系统对截瘫患者的刺激模式；(2)对已开发的便携式上肢功能电刺激系统的改进；(3)膝关节支架的设计；(4)电锁定机构的设计；(5)混合式功能电刺激系统在截瘫患者中的临床应用。结果表明：(1)混合式功能电刺激系统在截瘫患者中的刺激模式；(2)便携式上肢电刺激系统的改进；(3)膝关节支架的设计；(4)电锁定机构的设计；(5)混合式功能电刺激系统在截瘫患者中的临床应用我们开发的混合式FES系统使截瘫患者能够以最小的疲劳感稳定地站立，这是因为电动锁/解锁支架锁定了膝盖。患者还可以使用自己控制的混合FES系统站立后行走，只需简单的切换程序。

The purpose of this research is to develop a hybrid Functional Electrical Stimulation (FES) system combinated with a knee brace, which has an electrical locking mechanism for standing up and walking in the paraplegics.(1) Stimulation pattern of the hybrid FES system for lower extremities, (2) modification of the portable FES system for upper extremities which we had already developed, (3) Designing of a knee brace, (4) Planning of an electrical locking mechanism, (5) Clinical application of the hybrid FES system in a paraplegic patient were studied.As the result, the hybrid FES system which we developed enabled the paraplegic patient to stand up stably with minimum fatigue because of the locking of the knee by the electrical lock/unlock brace. And the patient also could walk after standing by using the hybrid FES system controlled by himself with a simple switching procedure.
