Cards

Term
motor control
Definition
ability to regulate or direct the mechanisms essential to movement
Term
motor program
Definition
abstract representation of movement that results in production of coordinated movement sequence
Term
motor plan
Definition
idea or plan for purposeful movement that s made up of several component motor programs
Term
neuroplasticity
Definition
neural modifiability

short term change: efficiency or strength of synaptic connections

Long term change: organization and #s of neural connections
Term
motor learning
Definition
Internal processes associated with practice or experience leading to relatively permanent changes in capacity for skilled behavior
Term
associative learning
Definition
One stimulus to another (Classical conditioning)
One’s behavior to consequence (Operant conditioning)
Term
feedback
Definition
Response-produced information received during or after the movement; monitor output for corrective actions
Term
feedforward
Definition
Response-produced information received during or after the movement; monitor output for corrective actions
Term
lethargic
Definition
slow to respond, drowsy
Term
obtunded
Definition
dull, blunted response, difficult to arouse, appears confused
Term
stupor
Definition
semiconscious, aroused only with intense stimuli
Term
coma
Definition
no response to stimuli
Term
attention
Definition
the ability to focus and maintain one’s consciousness on a particular stimulus or task without being distracted by other stimuli.
Term
Fluent aphasia/Wernike’s
Definition
Speech that flows smoothly but contains errors
Neologisms- nonsense words
Circumlocutions- word substitution
Circling around the word b/c can remember it
Term
Nonfluent aphasia/Broca’s
Definition
Anomia – lack of name/word
Speech that is slow and hesitant with limited vocabulary and impaired syntax
Term
ideomotor apraxia
Definition
movement is automatic, not on command
Term
ideational apraxia
Definition
Purposeful movement not possible, worse out of the two
Term
yerkes-dodson law
Definition
very low or very high arousal are detrimental to performance
Term
Closed loop system of motor control
Definition
uses feedback, somatosensation
Term
open-loop system of motor control
Definition
does not use feedback or error detection, usually rapid/well learned movements
Term
tone
Definition
Resistance of muscle to passive elongation or stretch while attempting to maintain muscle relaxation
Factors
Term
spasticity
Definition
velocity dependent resistance to passive stretch
Term
decorticate rigity
Definition
UE flex, LE ext
disinhibition of red nucleus
lesion above superior colliculus
Term
decerebrate rigidity
Definition
UE & LE ext
lesion between superior colliculus and vestibular nucleus
Term
Opisthotonus
Definition
sustained contraction of neck and trunk extensors
Term
0 tone
Definition
no response (flaccidity)
Term
1+ tone
Definition
decreased response (hypotonia)
Term
2+ tone
Definition
normal response
Term
3+ tone
Definition
exaggerated response (hypertonia)
Term
4+ tone
Definition
sustained response (rigidity)
Term
0 MAS
Definition
no increase in muscle tone
Term
1 MAS
Definition
Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at the end of the range of motion when the affected part(s) is moved in flexion or extension
Term
1+ MAS
Definition
Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the ROM
Term
2 MAS
Definition
More marked increase in muscle tone through most of the ROM, but affected part(s) easily moved
Term
3 MAS
Definition
Considerable increase in muscle tone, passive movement difficult
Term
4 MAS
Definition
Affeced part(s) rigid in flexion or extension
Term
jendrassik maneuver
Definition
patient hooks fingers of hands together while LE reflexes are tested. Squeeze knees together or cross ankles for UE testing
Term
0 reflex integrity
Definition
No response (abnormal)

LMN syndrome
Term
1+ reflex integrity
Definition
decreased response (hyporeflexia)
Term
2+ reflex integrity
Definition
Normal response
Term
3+ reflex integrity
Definition
Brisk response (hyperreflexia)
Term
4+ reflex integrity
Definition
Very brisk, hyperactive, 1-3 beat clonus (abnormal) UMN syndrome
Term
5+ reflex integrity
Definition
>3 beat clonus or sustained response (abnormal)
UMN syndrome
Term
chaddock reflex
Definition
stroke laterla ankle/foot
Term
oppenheim reflex
Definition
stroke down medial tibial crest
Term
flexor withdrawal
Definition
Knee flexion, hip ABD ER Flex, DF and eversion
Term
ATNR
Definition
Extensors will be activated on side you are looking at and flexors on the other (fencing position)
Term
STNR
Definition
With flexion of neckflexion of UE’s/ext of LE’s
With extension of neck extension of UE’s/flexion of LE’s
Term
STLR
Definition
Person in supine extension of UE/LE/neck
Person in prone flexion of UE/LE/neck
Term
closed motor skill
Definition
performed in a stable, non-changing environment
Term
open motor skill
Definition
performed in a variable, changing environment
Term
limits of stability
Definition
maximum distance able to lean in any direction without loss of balance
Term
generalizability
Definition
Extent to which practice on one task contributes to the performance of other, related skills
