Twenty-six ambulatory children underwent preoperative and 1-year postoperative assessments after selective dorsal rhizotomy. These included spasticity, passive range of motion, tone, three-dimensional motion analysis, and electromyography. Independent and dependent ambulators were evaluated separately. A decrease in spasticity was found in all lower extremity muscle groups. An increase in passive range of motion was found only at the hip for both independent and dependent ambulators. Gait changes included increases in velocity and stride length in the independent ambulators. An improvement in hip extension during stance was found in the dependent ambulators only; however, an increase in knee extension and dorsiflexion in stance were seen in both groups. Selective dorsal rhizotomy improves both passive and dynamic range of motion in children with spastic diplegia.
26名门诊患儿在接受选择性背根切断术后进行了术前和术后1年的评估。这些评估包括痉挛程度、被动活动范围、肌张力、三维运动分析和肌电图检查。独立行走和依赖他人行走的患儿分别进行了评估。所有下肢肌肉群的痉挛程度均有所降低。仅在独立行走和依赖他人行走的患儿中，髋关节的被动活动范围有所增加。步态变化包括独立行走患儿的速度和步幅增加。仅在依赖他人行走的患儿中发现站立时髋关节伸展有所改善；然而，两组患儿在站立时膝关节伸展和背屈均有所增加。选择性背根切断术可改善痉挛性双侧瘫患儿的被动和动态活动范围。
