Functional electrical stimulation can be used to provide hand opening in hemiplegics with spastic finger flexor muscles through stimulation of the extensor digitorum communis (EDC) muscle and the ulnar nerve. Stimulation of the finger extensor muscles in both hemiplegics and nonneurologically impaired individuals does not appear to cause significant reciprocal inhibition of finger flexor muscles. Thus stimulation of the EDC and ulnar nerve may not decrease finger flexor spasticity in the hemiplegic subjects, yet functional hand opening can still be obtained through a direct mechanical effect of the extensor stimulation.
功能性电刺激可通过刺激指总伸肌（EDC）和尺神经，用于为手指屈肌痉挛的偏瘫患者提供手部伸展。在偏瘫患者和无神经功能障碍的个体中，刺激手指伸肌似乎不会导致手指屈肌产生明显的交互抑制。因此，刺激EDC和尺神经可能不会降低偏瘫患者手指屈肌的痉挛程度，但通过伸肌刺激的直接机械效应仍可实现功能性手部伸展。
