本研究的目的是证实动态和固定马蹄骨畸形对膝关节后屈（过伸）时间影响的假设。根据我们的假设，动态马蹄足与早期和固定马蹄足以及晚期膝关节过伸有关。将35例脑瘫患儿（47条下肢）根据最大膝关节过伸时间分为两个亚组。临床检查证实了我们的假设。步态分析和肌肉骨骼建模结果与12名正常发育的儿童进行了比较。两组均为前足着地，均未达到正常踝关节背屈。肌电图检查显示单站立时比目鱼肌活动异常高。内侧腓肠肌和比目鱼肌的肌肉长度变化符合我们的假设。这一发现可能简化了选择治疗膝后翻患者马蹄形畸形的决定。[J]儿科骨科杂志（英文版）：366-372 (c) 2010 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins。
The aim of the study was to confirm the hypothesis of the influence of the dynamic and fixed equinus deformity on the timing of knee recurvation (hyperextension). According to our hypothesis, dynamic equinus is linked to early and fixed equinus and to late knee hyperextension. A group 35 children with cerebral palsy (47 lower limbs) was divided into two subgroups according to the timing of maximum knee hyperextension. Clinical examination confirmed our hypothesis. Gait analysis and musculoskeletal modelling results were compared with 12 normally developing children. Both recurvatum groups had forefoot landing and neither achieved normal ankle dorsiflexion. Electromyographic examination revealed an abnormally high soleus activity in a single stance. Muscle length changes of medial gastrocnemius and soleus were in agreement with our hypothesis. Such a finding might simplify the decision as to which treatment to select for equinus deformity, present in patients with genu recurvatum.
