The purpose of this article has been to present a theoretical construct that would enhance our understanding of the basis of the disorder apraxia of speech, whether it be developmental or acquired. From a theoretical explanation a conceptual framework was developed to guide the selection of appropriate treatment strategies. DAS, like acquired apraxia of speech, is conceived here as a sensorimotor impairment. The sensorimotor impairment is based on reduced or aberrant reafference. Thus, tactile or kinesthetic methods of treatment, as well as treatment techniques that may facilitate the processing of peripheral sensation (such as slowed speech), have been proposed as being the most facilitative. The hypotheses proposed herein require extensive investigation. Nonetheless, according to a number of clinical reports, methods that highlight movement sequences and methods that heighten the melodic line and slow rate are the ones that have gained the greatest favor in the treatment of children with DAS and adults with acquired apraxia of speech.
本文的目的是提出一种理论架构，以增进我们对言语失用症（无论是发育性还是后天性）基础的理解。基于理论解释构建了一个概念框架，以指导适当治疗策略的选择。在这里，发育性言语失用症与后天性言语失用症一样，被视为一种感觉运动障碍。这种感觉运动障碍基于反馈减少或异常。因此，已提出触觉或动觉治疗方法以及可能有助于外周感觉处理的治疗技术（如放慢语速）是最有帮助的。本文提出的假设需要广泛研究。尽管如此，根据一些临床报告，突出运动序列的方法以及提高旋律线和放慢语速的方法在治疗发育性言语失用症儿童和后天性言语失用症成人方面最受青睐。
