有语言错误的儿童如果运动技能下降，可能更容易发展出与终身挑战相关的残余错误。利用强调体感敏锐度在更新运动计划中的作用的语言产生模型，本初步研究探讨了儿童运动技能和语言准确性之间的关系，以及体感敏锐度和运动技能之间的关系。理解感觉运动测量和语言结果之间的联系，可以深入了解在语言产生过程中身体感觉和运动技能是如何合作的，这可以为这类人群的治疗决策提供信息。25名儿童（9-14岁）在超声生物反馈治疗方案前后在/ r /刺激任务中产生音节。我们首先测试了运动技能（通过两种基于舌头形状复杂性的超声指标来衡量）是否预测了声学测量的准确性（第二和第三峰频率之间的标准化差异）。然后，我们测试了体感灵敏度（通过口腔立体感知任务测量）是否预测了运动技能，同时控制了听觉灵敏度。舌形复杂程度的一项测量是准确性的重要预测因子，因此，较高的舌形复杂程度与预处理时较低的准确性相关，而与处理后较高的准确性相关。基于同样的测量，体感敏锐度更好的儿童产生了更复杂的/ r /舌形，但这种关系仅在治疗后出现。在治疗后观察到体感敏锐度、运动技能和声学测量/音/音生产精度之间的预测关系，但出乎意料的是，在治疗前不成立。令人惊讶的发现，舌形复杂程度越高，治疗前的准确性越低，这突出了在治疗前评估舌形模式（例如，使用超声波）的重要性，并有可能表明，在治疗前舌形复杂程度高的儿童可能是超声治疗的良好候选者。
Children with speech errors who have reduced motor skill may be more likely to develop residual errors associated with lifelong challenges. Drawing on models of speech production that highlight the role of somatosensory acuity in updating motor plans, this pilot study explored the relationship between motor skill and speech accuracy, and between somatosensory acuity and motor skill in children. Understanding the connections among sensorimotor measures and speech outcomes may offer insight into how somatosensation and motor skill cooperate during speech production, which could inform treatment decisions for this population. Twenty-five children (ages 9–14) produced syllables in an /ɹ/ stimulability task before and after an ultrasound biofeedback treatment program targeting rhotics. We first tested whether motor skill (as measured by two ultrasound-based metrics of tongue shape complexity) predicted acoustically measured accuracy (the normalized difference between the second and third formant frequencies). We then tested whether somatosensory acuity (as measured by an oral stereognosis task) predicted motor skill, while controlling for auditory acuity. One measure of tongue shape complexity was a significant predictor of accuracy, such that higher tongue shape complexity was associated with lower accuracy at pre-treatment but higher accuracy at post-treatment. Based on the same measure, children with better somatosensory acuity produced /ɹ/ tongue shapes that were more complex, but this relationship was only present at post-treatment. The predicted relationships among somatosensory acuity, motor skill, and acoustically measured /ɹ/ production accuracy were observed after treatment, but unexpectedly did not hold before treatment. The surprising finding that greater tongue shape complexity was associated with lower accuracy at pre-treatment highlights the importance of evaluating tongue shape patterns (e.g., using ultrasound) prior to treatment, and has the potential to suggest that children with high tongue shape complexity at pre-treatment may be good candidates for ultrasound-based treatment.
