Chapter 3: MSD exam Flashcards
What are the three components of the motor speech examination?
The three components of the motor speech examination are the 1. history 2. identification of salient features 3. identification of confirmatory signs.
History
The history provides information about time of onset, course of development, patients complaints and observations. It also provides an opportunity to listen to the patient’s speech without them knowing you are listening to their speech.
Salient Features
Features that contribute most directly to the diagnosis and most influence the diagnosis.
What are the Salient Neuromuscular features?
- Strength
- Speed
- Range
- Steadiness
- Tone
- Accuracy
Strength
In oder to perform appropriately, muscles have to have a certain strength. Muscle weakness can affect the 3 major speech valves: laryngeal, velopharyngeal, and articulatory. Muscle weakness can also impact the other components of speech production such as respiration, phonation, resonance, and prosody. Muscle weakness is the most prominent in flaccid dysarthria.
Speed
All speech movements require speed. Speech requires quick, unsustained and discrete movements which are called phasic movements. Phasic movements can be single muscle contractions or repetitive contractions. Phasic movements are controlled primarily through UMN input.
Speed cont.
The affects of slow movement is most seen in spastic dysarthria.
Range
decreased ROM is common and can be associated with slow or excessive speeds. ROM can vary with ataxic dysarthria. Patient’s can over or undershoot the targets- dysmetria.
Steadiness
lack of steadiness manifest itself in motor speech disorders as a tremor or other hyperkinesias.
Steadiness cont.
Tremors may be mild to severe and may affect speech as well as other parts of the body. Tremors can affect phonation and sometimes prosody. The effects of tremors in speech can best be heard in vowel prolongation. Tremors may be seen in non speech task involving the oral mechanism. Tremors can be resting tremors, intentional tremors, and terminal tremors ( at the end of a movement).
Steadiness cont.
The other hyperkinesias include dystonias, choreas, athetosis which may interfere with or be present during speech.
Tone
Tone refers to muscle tone and may either be hypo or hyper.
Accuracy
accurate movements are required for speech. inaccurate moments can result in speech errors. If there is too much f ROM the articulators may overshoot the target and vice versa. Innacurate movements also affect the major speech valve which are laryngeal, velopharyngeal and articulatory.
Confirmatory Signs
Confirmatory signs are additional clues about the pathology in the nervous system. These are signs other than the problematic speech characteristics noted and other than the neuromuscular symptoms. Confirmatory signs help support the speech diagnosis.
Confirmatory signs within the speech system
Confirmatory signs within the speech system are : atrophy, fasciculations, reduced tone, emotional lability ( spastic dysarthria), reduced normal reflexes, and pathological reflexes (spastic dysarthria)
Confirmatory signs of the nonspeech motor system
Confirmatory signs of the non speech motor system are : gait, muscle stretch reflexes, pathological reflexes, hyperactive limb reflexes, limb atrophy and fasciculations.
What does the history consist of?
introduction and goal setting basic data Onset and course of speech deficit Associated deficits Patient's perception of deficits Consequences of the disorder Management Awareness of diagnosis and prognosis
The history consist of?
Introduction and Goal setting- ask the pt why they are there. This gives you information about the patients perceptions, complaints etc.
