What does structural adequacy refer to?

Structural adequacy pertains to the development of orofacial structures—such as the lips, tongue, teeth, and palate—and how these anatomical features and relationships contribute to effective communication. This concept is essential in speech-language pathology because any abnormalities or developmental issues in these structures can influence a person’s ability to articulate sounds clearly, which is foundational for speech development.

Understanding structural adequacy helps clinicians assess whether an individual's physical capabilities align with the demands of speech production. This includes evaluating the functionality and coordination of the organs involved in speech. An optimal configuration and functioning of orofacial structures can significantly enhance speech clarity and intelligibility.

In contrast, emotional stability, bilingual proficiency, and fluent speech production are important aspects of communication but do not directly relate to the physical characteristics and development of the orofacial structures involved in speech. Hence, structural adequacy focuses specifically on the anatomical and functional aspects that enable effective verbal communication.
