We examined receptive language developmental trajectories between 18 months and 54 months for three clinical speech-language profile groups of children with cerebral palsy (those with speech motor involvement, without speech motor involvement, and with anarthria) and quantified differences from age-level expectations. We identified latent classes of comprehension development, related these classes to clinical profile groups, and examined how well early receptive language predicted outcomes.
We used a prospective longitudinal design. Eighty-five children with cerebral palsy (43 females, 42 males) were followed longitudinally from 18 to 54 months of age. Children were seen two to eight times (322 data points). Children were classified into clinical profile groups. Language comprehension age-equivalent scores were the primary measures of interest.
Children with anarthria had significant language delays, limited developmental change over time, and comprised their own latent class. Children with speech motor impairment had slight receptive language delays over time. Children with no speech motor impairment had age-appropriate receptive language over time. Early language comprehension scores were highly predictive of later latent profile group membership.
Early language comprehension abilities are highly predictive of language comprehension growth trajectory and suggest that children with early language delay, particularly those who are non-speaking, should receive language intervention to support development.
There are two growth trajectories for language comprehension among children with cerebral palsy. Children with speech motor impairment had a constant 6-month receptive language delay. Children without speech motor impairment had age-appropriate receptive language. Non-speaking children had significant receptive language delay. Early language comprehension change was highly predictive of later trajectory group.
我们研究了脑瘫儿童三个临床言语语言特征组（有言语运动障碍、无言语运动障碍和无言语症）从 18 个月到 54 个月的接受性语言发展轨迹，并量化了与年龄水平预期的差异。我们确定了理解发展的潜在类别，将这些类别与临床特征组相关联，并检查了早期接受性语言预测结果的能力。
我们采用前瞻性纵向设计。85 名脑瘫儿童（43 名女性，42 名男性）从 18 个月到 54 个月进行了纵向随访。儿童每 2-8 次（322 个数据点）就诊一次。儿童被分为临床特征组。语言理解年龄等效分数是主要的研究指标。
无言语症儿童语言严重延迟，随时间变化的发展有限，且构成了自己的潜在类别。有言语运动障碍的儿童随时间有轻微的接受性语言延迟。无言语运动障碍的儿童随时间有适当的接受性语言。早期语言理解得分对后期潜在特征组的成员具有高度预测性。
早期语言理解能力对语言理解增长轨迹具有高度预测性，这表明早期语言延迟的儿童，特别是那些不说话的儿童，应该接受语言干预以支持其发展。
脑瘫儿童的语言理解有两种增长轨迹。有言语运动障碍的儿童有持续的 6 个月接受性语言延迟。无言语运动障碍的儿童有适当的接受性语言。不说话的儿童有明显的接受性语言延迟。早期语言理解变化对后来的轨迹组具有高度预测性。
