Three-dimensional ultrasound (3-DUS) was used to examine the size and appearance of the medial gastrocnemius (MG) muscle in children with unilateral cerebral palsy (CP). Twenty-six children with CP and 10 typically developing (TD) children participated. Three-dimensional US images of both limbs in children with CP and the right limb in TD children were analysed using quantitative methods to determine muscle volume, global echo intensity, global echo pattern and regional echo intensity. Significant differences in MG volume and all echo parameters were found between TD and CP children. The more involved limb was smaller and had higher echo intensity and a more heterogenous echo pattern compared with the TD group. Compared with that of the more involved limb, the MG of the less involved limb was larger but had a similar echo appearance. The MG of both limbs in children with unilateral spastic CP is smaller and, based on quantitative ultrasound, structurally different from that of TD children.
采用三维超声（3-DUS）检查单侧脑瘫（CP）患儿腓肠肌内侧头（MG）的大小和外观。26例CP患儿和10例发育正常（TD）儿童参与研究。采用定量方法分析CP患儿双下肢及TD儿童右下肢的三维超声图像，以确定肌肉体积、整体回声强度、整体回声模式和局部回声强度。发现TD儿童与CP患儿的MG体积及所有回声参数存在显著差异。与TD组相比，受累更严重的肢体较小，回声强度更高，回声模式更不均匀。与受累更严重的肢体相比，受累较轻肢体的MG更大，但回声外观相似。单侧痉挛型CP患儿双下肢的MG较小，基于定量超声检查，其结构与TD儿童不同。
