Motor Speech Disorders Apraxia and Dysarthria by Mind Map: Motor Speech Disorders   Apraxia and Dysarthria

1. Speech Motor Control

1.1. An individual's control over the muscular coordination invovled with producing speech

2. Motor Speech disordr

2.1. An impairment of speech production caused by defects of the neuromuscular system.

3. Respiratory system

3.1. Regulates the inhalation-exhalation cycle for passive breathing and for producing speech

4. Phonatory System

4.1. Regulates the production of voice and the prosodic, or intonational, aspects of speech

5. Resonatory system

5.1. Regulates the resonation or vibration of the airflow as it moves from the pharynxx into the oral or nasal cavities.

6. Velopharyngeal port

6.1. the opening between the velum (soft palate) and the back of the pharynx wall

7. Articulatory sytem

7.1. Regulates the control of the articulators within the oral cavity to manipulate the outgoing airflow in different ways, usually at very high speeds.

8. Motor Program

8.1. muscle synergy, an abstract representation of a relatively invariant movement pattern that can be scaled in size and time to meet the demands of the particular situation.

9. Motor Learning

9.1. the way in which practice or experience leads to "relatively" permanent changes in the capability for movement.

10. schemas

10.1. Memory representations of relationships between various sources of information

11. Motor planning and programming disorders

11.1. caused by an inability to group and sequence the relevant muscles in order to plan or program a movement

12. Motor execution disorders

12.1. Caused by deficits or inefficiencies in basic physiological or movement characteristics of the musculature, such as muscle tone, movement speed, and movement range.

13. Dysarthria

13.1. A group of speech disorders caused by disturbances of neuromuscular control of the speech production systems

14. Muscle tone

14.1. The resistance to passive movement and reflects sustained muscle activity that provides postural support for active movements.

15. Muscle strength

15.1. The ability of the muscle to contract to a desired level and may be reduced, as in flaccid dysarthria.

16. Movement steadiness

16.1. The ability of the muscles to generate steady movements and may be disrupted by involuntary movements.

17. Generalization

17.1. Application or transfer of a skill to related but untrained movement patterns.

18. Conditions of Practice

18.1. 1.

18.1.1. Practice variability Conditions of practice refer to factors such as the number of different targets practicied

18.2. 2.

18.2.1. Practice schedule The order in which different targs are practiced

18.3. 3.

18.3.1. Practice Amount Number of practice trials

18.4. 4.

18.4.1. Practice Distrubution How close in time the practice sessions are spaced

19. Feedback frequency

19.1. How often the learner receives feedback

20. Feedback Timing

20.1. How soon after an attempt the learner receives feedback
