In twenty-three patients with cerebral palsy and functional spastic hemiplegia, the contracted thenar-adductor space of the involved hand was evaluated by electromyography. The needle electromyogram was used to determine if the patient had selective control of the adductor muscle. In eight patients only partial myotomy of the adductor muscle during z-plasty of the web was performed because selective control of that muscle was present during either grasp or release. In four patients a complete release was done, and in two of them the ability to pinch was impaired.
对23例患有脑瘫和功能性痉挛性偏瘫的患者，通过肌电图评估患侧手部收缩的大鱼际内收肌间隙。采用针电极肌电图来确定患者是否能选择性控制内收肌。8例患者在蹼状切开成形术期间仅对内收肌进行部分肌切开术，因为在抓握或松开过程中该肌肉存在选择性控制。4例患者进行了完全松解，其中2例捏力受损。
