: To compare muscle strength, ankle dorsiflexion range of motion (ROM), motor coordination and balance, between children with and without Idiopathic Toe Walking (ITW). This is an observational case-control study. The primary outcome is the triceps surae muscle strength. The secondary outcomes are the anterior tibialis muscle strength, lower limb balance, motor coordination, and ankle dorsiflexion ROM. Thirty-eight children were recruited: 19 between 5 to 11 years old with ITW and 19 healthy (control). Ankle dorsiflexion ROM, triceps surae, anterior tibialis muscle strength, motor coordination, and balance were assessed. Children with ITW showed reduced triceps surae strength [mean difference (MD): 16.2 kgf/kg100; 95% confidence interval (CI) -32.72 to 0.28; = .05], reduced anterior tibialis strength (MD: 8.5 kgf/kg100; 95% CI -13.35 to -3.05; p ≤ 0.001), reduced ankle dorsiflexion ROM (MD: 19.6 degrees; 95% CI 15.43 to 23.77; p ≤ 0.001) and impaired motor coordination and balance (MD: 17.7; 95% CI -25.54 to -9.82; p ≤ 0.001) compared to healthy children. Children with Idiopathic Toe Walking, presented in this study, demonstrated triceps surae and anterior tibialis muscle strength reduction, ankle dorsiflexion ROM reduction, impaired motor coordination, and balance compared to healthy children.
比较特发性趾行儿童与非特发性趾行儿童之间的肌肉力量、踝关节背屈活动度（ROM）、运动协调能力和平衡能力。这是一项观察性病例对照研究。主要结局是比目鱼肌力量。次要结局是胫骨前肌力量、下肢平衡、运动协调能力和踝关节背屈 ROM。共招募了 38 名儿童：19 名 5 至 11 岁特发性趾行儿童和 19 名健康对照儿童。评估了踝关节背屈 ROM、比目鱼肌、胫骨前肌力量、运动协调能力和平衡能力。特发性趾行儿童的比目鱼肌力量减弱[平均差异（MD）：16.2 公斤力/公斤100；95%置信区间（CI）-32.72 至 0.28；= .05]，胫骨前肌力量减弱（MD：8.5 公斤力/公斤100；95% CI -13.35 至-3.05；p ≤ .001），踝关节背屈 ROM 减小（MD：19.6 度；95% CI 15.43 至 23.77；p ≤ .001），运动协调和平衡能力受损（MD：17.7；95% CI -25.54 至-9.82；p ≤ .001），与健康儿童相比。本研究中，特发性趾行儿童表现出比目鱼肌和胫骨前肌力量减弱、踝关节背屈 ROM 减小、运动协调能力受损和平衡能力下降。
