Dysarthria
Pronunciation: dis-AR-three-ah
A motor speech disorder affecting articulation and intelligibility that physical therapists may address through respiratory and oral motor interventions.
Full Definition
Dysarthria is a motor speech disorder characterized by weakness, slowness, or incoordination of the speech mechanism, resulting in unclear or difficult-to-understand speech. While primarily treated by speech-language pathologists, physical therapists play a crucial role in addressing underlying respiratory support, postural control, and oral motor function that contribute to speech intelligibility. Physical therapy interventions may include breathing exercises, postural training, and coordination activities that support speech production. The condition can result from various neurological conditions including stroke, traumatic brain injury, Parkinson's disease, or multiple sclerosis. Physical therapists must understand the relationship between respiratory function, postural stability, and speech clarity when developing comprehensive treatment plans.
Usage
Usage note: Do not confuse with dysphasia (language disorder) or dysphagia (swallowing disorder). Specify the type when known (e.g., spastic, flaccid, ataxic dysarthria).
