目的比较唐氏综合征（DS）和正常发育（TD）儿童的扁平足外翻程度、踝关节肌肉质量和足部肌肉质量。我们还研究了患有DS和TD的儿童的扁平足外翻程度与踝关节和足部肌肉的肌肉质量之间的关系。受试者为24名TD儿童（对照组）和23名DS儿童（DS组）。为了评估扁平足，测量了站立位的足弓高度指数（AHI）。使用超声成像装置测量踝关节和足部肌肉的肌肉厚度。DS组比目鱼肌和胫骨后肌的AHI和厚度显著低于CTR组。DS组趾长屈肌厚度明显大于CTR组。逐步回归分析显示，趾长屈肌厚度是CTR组和DS组儿童AHI的显著独立因素。趾长屈肌厚度随AHI的降低而增加。本研究的结果表明，AHI和比目鱼肌和胫骨后肌的肌肉质量减少，而屈趾长肌的肌肉质量增加，在DS儿童。结果还表明，降低AHI与儿童趾长屈肌肌肉质量增加有关。
We aimed to compare the degree of pes planovalgus and muscle mass of the ankle joint and foot muscles between children with Down syndrome (DS) and children with typical development (TD). We also examined the association of the degree of pes planovalgus with muscle mass of the ankle joint and foot muscles in children with DS and children with TD. The subjects were 24 children with TD (control [CTR] group) and 23 children with DS (DS group). To assess pes planovalgus, the Arch Height Index (AHI) in the standing position was measured. Muscle thickness of the ankle joint and foot muscles was measured using an ultrasound imaging device. The AHI and thickness of the soleus and tibialis posterior muscles were significantly lower in the DS group than those in the CTR group. The thickness of the flexor digitorum longus muscle was significantly greater in the DS group than that in the CTR group. Stepwise regression analysis revealed that the thickness of the flexor digitorum longus muscle was a significant and independent factor of the AHI in children comprising the CTR and DS groups. The thickness of the flexor digitorum longus muscle increased with decreasing AHI. The results of this study suggest that the AHI and muscle mass of the soleus and tibialis posterior muscles decrease, while muscle mass of the flexor digitorum longus muscle increases in children with DS. The results also indicate that decreased AHI is associated with increased muscle mass of the flexor digitorum longus muscle in children.
