Although weakness has been identified in cerebral palsy (CP) in isolated muscle groups, the magnitude of weakness in multiple muscles and the patterns of weakness across joints have not been documented. The maximum voluntary contraction of eight muscle groups in the lower extremities of 15 children with spastic diplegia, 15 with spastic hemiplegia, and 16 age-matched peers was determined using a hand-held dynamometer. Children with spastic diplegia were shown to be weaker than age-matched peers in all muscles tested, as were the children with hemiplegia on the involved side, with strength differences also noted on the uninvolved side. Weakness was more pronounced distally in the groups with CP, and the hip flexors and ankle plantarflexors in spastic CP tended to be relatively stronger than their antagonists as compared with the strength ratios of the comparison group. In conclusion, children with spastic CP demonstrate quantifiable lower-extremity weakness and muscle imbalance across joints.
尽管已确定脑瘫（CP）患者存在孤立肌肉群的无力，但多块肌肉的无力程度以及关节间的无力模式尚未有文献记载。使用手持式测力计测定了15例痉挛性双侧瘫患儿、15例痉挛性偏瘫患儿以及16例年龄匹配的同龄人下肢八组肌肉的最大自主收缩。结果显示，痉挛性双侧瘫患儿在所有测试肌肉中均比年龄匹配的同龄人弱，偏瘫患儿患侧的情况也是如此，未患侧也存在力量差异。CP组患儿的无力在远端更为明显，与对照组的力量比相比，痉挛性CP患儿的髋屈肌和踝跖屈肌往往相对比其拮抗肌更强。总之，痉挛性CP患儿表现出可量化的下肢无力以及关节间的肌肉失衡。
