Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), [1] is a condition in which an individual has problems saying sounds, syllables and words. This is not because of muscle weakness or paralysis.
One such current debate relates to the efficacy of oral motor exercises and the expectations surrounding them. According to Lof, [19] non-speech oral motor exercises (NS-OME) includes "any technique that does not require the child to produce a speech sound but is used to influence the development of speaking abilities". These sorts of exercises ...
Fine motor planning, control and coordination are often affected. [117] Dysarthria, a speech disorder resulting from neurological damage to the motor-speech system, occurs in an estimated 31% to 88% of those with cerebral palsy. Such individuals may require AAC support for communication.
Dysarthria is the reduced ability to motor plan volitional movements needed for speech production as the result of weakness/paresis and/or paralysis of the musculature of the oral mechanism needed for respiration, phonation, resonance, articulation, and/or prosody.
Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), [3] [4] is an inability to utilize motor planning to perform movements necessary for speech during a child's language learning process. Although the causes differ between AOS and DVD, the main characteristics and ...
Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes. [2] It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.
Dysarthria is a motor speech disorder caused by damage to the central and/or peripheral nervous system, and it is related to degenerative neurological diseases, such as Parkinson's disease, cerebrovascular accident (CVA), and traumatic brain injury (TBI). [13]
[3] [7] Expressive aphasia differs from dysarthria, which is typified by a patient's inability to properly move the muscles of the tongue and mouth to produce speech. Expressive aphasia also differs from apraxia of speech, which is a motor disorder characterized by an inability to create and sequence motor plans for conscious speech. [8]
