Duffy Motor Speech Flashcards
Combined processes of speech motor planning, programming, control and execution
Motor Speech Processes
Speech disorders resulting from neurological impairments affecting the planning, programming, control or execution of speech.
Motor speech disorders
Collective name for neurological speech disorders that reflect abnormalities in speech, speed, range, steadiness, tone or accuracy of movements required for breathing, phonatory, resonatory, articulatory or prosodic aspects of speech production
Dysarthria
A neurological speech disorder that reflects impaired capacity to plan or program sensorimotor commands necessary for during movements that result in phonetically and prosodically normal speech
Apraxia of speech
Rely primarily on auditory perceptual attributions of speech
Perceptual
The three instrumental analsysis of speech
Acoustic, physiological and visual imaging
Methods that can visually display and numerically quantify frequency, intensity, temporal component of speech
Acoustic
Measurement that focuses on muscles contractions that generate movements
Physiologic
What are the the factors of categorising motor speech disorders?
Age at onset, course, site of lesion, neurological diagnosis, pathophysiology
What are the variables relevant to speech disorders?
Speech components involved, severity and perceptual characeristics
What is the localisation of flaccid dysarthria and neuromotor bases specific?
Lower motor neuron and weakness
What is the localisation of spastic dysarthria and neuromotor bases specific?
Bilateral upper motor neuron and spasticity
What is the localisation of ataxic dysarthira and neuromotor bases specific?
Cerebellum and incoordination
What is the localisation of hypokinetic dysarthria and neuromotor bases specific?
Basal ganglia and rigidity
What is the localisation of hyperkinetic dysarthria and neuromotor bases specific?
Basal gangalia and involuntary movements
What is the localisation of apraxia and neuromotor bases specific?
Left hemisphere and programming
What do the final common pathways of speech include that supply muscles involving phonation, resonance, articulation and prosody as well as involved in speech breathing and prosody.
Paired cranial nerves and paired spinal nerves
What is the trigeminal nerve responsible for?
sensation of the face and anterior tongue, jaw motor movement, motor movement trigeminal nerve,
What is the facial nerve responsible for?
Motor muscles of the face and lip
What is the glosso pharyngeal nerve responsible for?
Raise and dilate of pharynx, taste sensation of the tongue, gag reflex
What is the vagus nerve for?
Motor muscles of the larynx, sensory of the lower larynx
What is the tongue nerve for?
Motor muscles of the tongue
Speech is manifested through movements triggered by what which innervate breathing, phonatory, resonatory and articulatory muscles
Spinal nerves and cranial nerves
What are the 3 essential components of motor speech examination
Case history, salient speech features and identify confirmatory signs
