Final answer:
Speech-language pathologists help children with all of the above options: sports injuries, problems due to trauma, and autism, as these conditions can affect speech, language, communication, and swallowing.
Step-by-step explanation:
Speech-language pathologists (SLPs) are professionals who specialize in the evaluation and treatment of communication and swallowing disorders. Among the populations that SLPs serve, children with autism spectrum disorder (ASD) are a primary group. Autism is characterized by deficits in social interaction, verbal and nonverbal communication, and engagement in repetitive behaviors or interests.
SLPs also help individuals who have suffered from trauma, as they might experience issues with language, cognition, and swallowing. This can also include problems due to sports injuries where the individual might have difficulty with speech, language, cognitive communication, and oral motor skills. In addition, SLPs assist those with developmental disabilities which can affect language, speech, and social communication.
Regarding the options presented in the question: a) Sports injuries, while not the primary focus, an SLP may assist if there are related communication or swallowing disorders; b) Problems due to trauma including cognitive communication deficits; and c) Autism, where SLPs often play a critical role. Therefore, the correct answer is d) All of the above.
