Severe muscular spasticity encountered frequently in patients with spastic cerebral palsy not only affects patient locomotor function but also causes musculoskeletal complications. Significant reduction of spasticity over pelvis and lower limbs after selective posterior rhizotomy (SPR) results in improvement of trunk stability, locomotor function, and function of upper limbs also. The purpose of this study was to investigate the difference of sitting balance before and after SPR using a quantitative measurement in sitting stability represented as dispersion index provided by the Chattecx Balance System. Seventeen children with spastic cerebral palsy, ten boys and seven girls, with a mean age of 5.06 yr, underwent SPR. Their sitting stability under static and dynamic, visual and nonvisual testing conditions was assessed before SPR and three mo after SPR. Their sitting balance showed significant improvement at postoperative evaluation except for the static-nonvisual testing condition. Dispersion index under the dynamic testing condition was significantly higher than under the static testing condition, which implies that dynamic sitting balance was worse than static sitting balance in these patients. There was no statistical difference of sitting performance between visual and nonvisual condition both preoperatively and postoperatively. Quantitative measurement of dispersion index provided by the Chattecx Balance System offers an objective evidence of improvement in sitting balance for children after SPR.
痉挛型脑瘫患者经常出现的严重肌肉痉挛不仅影响患者的运动功能，还会引发肌肉骨骼并发症。选择性后根切断术（SPR）后骨盆和下肢痉挛的显著减轻，不仅改善了躯干稳定性和运动功能，上肢功能也得到了改善。本研究的目的是使用Chattecx平衡系统提供的以离散指数表示的坐位稳定性定量测量方法，研究SPR前后坐位平衡的差异。17例痉挛型脑瘫儿童，10例男孩和7例女孩，平均年龄5.06岁，接受了SPR。在SPR前和SPR后3个月评估他们在静态和动态、视觉和非视觉测试条件下的坐位稳定性。除静态非视觉测试条件外，术后评估时他们的坐位平衡有显著改善。动态测试条件下的离散指数显著高于静态测试条件，这意味着这些患者的动态坐位平衡比静态坐位平衡差。术前和术后视觉和非视觉条件下的坐位表现均无统计学差异。Chattecx平衡系统提供的离散指数定量测量为SPR后儿童坐位平衡的改善提供了客观证据。
