Preoperative and postoperative gait analysis data were retrospectively studied for 54 children with cerebral palsy who had undergone either gastrocnemius recession (GR) or tendo-achilles lengthening (TAL) as part of multi-level surgery. Decision-making between GR and TAL was based on the Silfverskiöld test. The TAL group had greater equinus preoperatively than the GR group. Both groups showed significant improvement in static and dynamic dorsiflexion and in outcome measured by a modified Physician Rating Scale (PRS) postoperatively. Calf spasticity decreased and push-off power increased after GR. Both GR and TAL are effective in appropriately selected patients. However, a potential for over- and under-correction with both GR and TAL was demonstrated.
对54例接受了腓肠肌松解术（GR）或跟腱延长术（TAL）作为多级手术一部分的脑瘫患儿的术前和术后步态分析数据进行了回顾性研究。GR和TAL之间的决策基于西尔弗斯基öld试验。TAL组术前马蹄足比GR组更严重。两组术后在静态和动态背屈以及通过改良医师评分量表（PRS）测量的结果方面均显示出显著改善。GR术后小腿痉挛减轻，蹬地力量增加。GR和TAL对适当选择的患者均有效。然而，GR和TAL均显示出过度矫正和矫正不足的可能性。
