It is an allied health profession regulated by professional bodies including the American Speech-Language-Hearing Association (ASHA) and Speech Pathology Australia.SLPs also play an important role in the screening, diagnosis, and treatment of autism spectrum disorder (ASD), often in collaboration with pediatricians and psychologists.Services are provided in the following areas: Speech, language, and swallowing disorders result from a variety of causes, such as a stroke,[7] brain injury,[8] hearing loss,[9] developmental delay,[10] a cleft palate,[11] cerebral palsy,[12] or emotional issues.Research has indicated that children who receive early language intervention are less likely to develop compensatory error patterns later in life, although speech therapy outcomes are usually better when surgical treatment is performed earlier.Experimental, empirical, and scientific methodologies that build on hypothesis testing and logical, deductive reasoning have dominated research in speech-language pathology.Following graduation and passing a nation-wide board exam, SLPs typically begin their Clinical Fellowship Year, during which they are granted a provisional license and receive guidance from their supervisor.When evaluating impairment-based level of breakdown, therapists are trained to use a cognitive neuropsychological approach to assessment, to precisely determine what aspect of communication is impaired.[31] Teleconferencing tools such as Skype are being used more commonly as a means to access remote locations in private therapy practice, such as in the geographically diverse south island of New Zealand.[34] Speech and language therapists work in acute settings and are often integrated into the MDT in multiple areas of speciality for neonatal, children and adult services.
