Exam 2 - PD - Chapter 6 Flashcards
____ control is required to perform tasks and activities necessary for independence and life fulfillment.
motor
_____ control is necessary for a person to function independently during occupational performance tasks.
motor
The ability to regulate or direct movement
motor control
Information is relayed to the _______ to organize the musculoskeletal system and create coordinated movements and skilled actions.
central nervous system
Movement involves these these 5 things
Perception Motor Planning Motor Execution Feedback Biomechanics
Making sense of input
perception
processing input
motor planning
carrying out movement
motor execution
relationship of muscles and joints to each other
biomechanics
When an insult to the CNS occurs or a progressive, neurologic disease develops, ______ is affected.
motor control
This theory says that movement is a function of interactions among the neuromuscular system, environment, cognition, and the task itself.
dynamical systems theory
This system includes the nervous system, muscular system, and skeletal systems, which interact to influence and produce movement.
neuromusculoskeletal
When examining the neuromusculoskeletal system, practitioners evaluate these three things
Physical appearance
Postural mechanism
Coordination
These mechanisms include postural tone, muscle tone, integration of the primitive reflexes and mass patterns of movement, righting reactions, equilibrium reactions, protective extension, and selective voluntary or intentional movement.
postural mechanisms
In patients who have sustained CNS damage secondary to a CVA or traumatic brain injury, the normal ______ mechanism is disrupted
postural
OT practitioners assess the degree of _____ to the postural mechanism in patients with CNS trauma or disease.
damage
This refers to muscle tension in the neck, trunk and limbs.
Postural tone
Postural tone must be high enough to resist _______, thus enabling persons to be upright against ______ yet low enough to allow _______.
gravity, gravity and movement
Abnormal muscle tone may be too low, resulting in poor ________ or too high, resulting in _______
stability, rigidity
This is a continuous state of mild contraction, or state of readiness of a specific muscle.
normal muscle tone
Muscle tone is the resting state of a muscle in response to ___ and _________.
gravity and emotion
The level and distribution of muscle tone change as the ___ changes
position of the patient’s head in space
When it comes to muscle tone, the OT is responsible for _________.
evaluating muscle tone and its distribution (and how it interferes with activities)
Abnormal muscle tone is described as these three categories
hypotonicity, hypertonicity, or rigidity
How does a person begin to “feel” the range of muscle tone
practice
Muscle tone increases with___ or ____
stress, difficulty
This is a decrease in mucle tone
hypotonicity or flaccidity
What is a symptom of flaccidity?
muscle feels soft and offers no resistance
This is a state of increased muscle tone
jasonicity
This is commonly defined as an increased resistance to passive stretch caused by an increased or hyperactive stretch reflex.
Hypertonicity or spasticity
Loud noises, bright lights, cool temps, and bright-colored cluttered walls may stimulate
muscle tone
This scale provides a uniform way to measure muscle tone in adults
Ashworth Tone Scale
MODIFIED ASHWORTH SCALE FOR GRADING SPASTICITY: Give me your score: No increase in muscle tone (0-4)
0
MODIFIED ASHWORTH SCALE FOR GRADING CAUSTICITY: Slight incrrease in muscle tone, manifested by a catch and release or by minimal resistance at the end of the ROM when the affected parts are moved in flexion or extension
1
MODIFIED ASHWORTH SCALE FOR GRADING SPASTICITY: More marked increase in muscle tone through most of the ROM, but affected parts easily moved
2
MODIFIED ASHWORTH SCALE FOR GRADING SPASTICITY: Considerable increase in muscle tone, passive movement difficult
3
MODIFIED ASHWORTH SCALE FOR GRADING SPASTICITY: Affected part(s) rigid in flexion or extension
4
This is an increase in muscle tone in the agonist and antagonist muscles simulatneously.
rigidity
This results from lesions of the extrapyramidial system such as in Parkinson’s disease, certain degenerative diseases, encephalitis, tumors
rigidity
TF - When asssessing ROM, move quickly, hold and wait to “feel” a release
F - move slowly
TF - Never inform the client of what is happening and the process.
F - Always inform them
These are innate motor responses elicited by specific sensory stimuli
reflexes
REFLEX: Response is suckling,
suck/swallow reflex
REFLEX: Extension of arm and leg on face side; flexion on arm and leg on skull side
aymmetrical tonic neck reflex
REFLEX - flexion of arms and extension of legs; Extension of Arms and flexion of legs
symmetrical tonic neck relex
REFLEX: Extension of trunk and extremities or increased extensor postural tone
TLR - Tonic Labarynthine reflex
REFLEX: Extension in leg stimulated
PSR - Positive Supporting Reflex
REFLEX: Extension of opposite leg
Crossed extension reflex
REFLEX: Flexion of digits into palmar grasp
Palmar grasp reflex
REFLEX: Flexion of toes
Plantar grasp reflex
What are used to protect the head and face when a person is off balance or falling?
Protective Extension Reactions
These maintain or restore the normal position of the head in space and it’s normal relationship with the trunk and limbs.
Righting Reactions
These maintain and restore a parson’s balance in all activities
Equilibrium reactions
ONe of the main factors that interfere with good quality of movement
sensory processing difficulties
What could help the OT practitioner understand the client’s volition for activities and his or her reaction to different environments
Observing clients in a variety of environments and performing a variety of activities
The ability to control movements at each individual joint
selective movement
This type of therapy helps clients regain motor functioning by promoting the USE of the AFFECTED extremity in daily activities
constraint-induced
The patient can use the involved upper extremity to stabilize objects being manipulated by the uninvolved extremity
Minimal stabilizing assist
The patient can use the involved upper extremity to assist actively in a single part of an activity.
Minimal active assist
The patient can use the involved arm and hand in all activities that require motor control for pushing or pulling, stabilizing, and gross grasp and release
maximal active assist
The patient can use the involved extremity to assist the uninvolved extremity in most occupational performance tasks, although speed and coordination may be impaired
Incorporation of involved upper extremity in all bilateral tasks
This tool is used to determine the client’s ability to complete ADLs
Functional Independence Measure
This is frequently considered an impairment to functional movement
abnormal muscle tone
This treatment frame of reference argues that clients must achieve typical muscle tone before moving
neurodevelopmental treatment (NDT)
The OT Practitioner must _______ increased muscle tone necessary for stability
facilitate
For hypotonia, the OT practitioner uses inhibitive techniques to decrease the
abnormal muscle tone
