resistance to contextual change

35
Q

what are the 3 ways of knowing if motor learning occurred

A

retention, generalizability of the skill, resistance to contextual change

36
Q

what are the 3 stages of motor learning

A

cognitive, associative, autonomous

37
Q

Person has to think or concentrate on the movement - high degree of cognitive activity
Consciously considering all strategies to accomplish movement
May even have to talk their way through the motion
Movements are typically stiff, inefficient, slow, non-fluid
May hesitate or not finish the movement
Have lots of errors in the movement
Trial and error needed

A

cognitive stage

38
Q

Best strategy for the task has been determined - no longer having to concentrate on the specifics of the movement
Using practice to refine the skill by making subtle adjustments
Addressing environmental demands of the movement
Less variability in performance in this stage

A

associative stage

39
Q

Requires very low amount of attention to the task
Skill is mostly automatic
Able to scan environment or perform two tasks at the same time
Paying too much attention in this stage might actually cause the motion to degrade

A

autonomous stage

40
Q

number of planes of motion possible at a single joint

A

DOF

41
Q

what are the 3 stages of motor learning by mastery of DOF

A

novice, advanced, expert

42
Q

fixing-learner co-activates muscles around a joint in order to allow another joint to move freely until the task is mastered

A

novice stage

43
Q

learner allows more joints to participate in the movement - less stiffness observed, more fluid, fewer errors, more efficient

A

advanced stage

44
Q

learner allows all DOF that are possible in a movement
Movement is efficient, learner able to adapt to speed, quality and coordination of movement

A

expert stage

45
Q

happens at cellular, tissue and organ levels within milliseconds

A

motor control

46
Q

happens over a period of hours, days and weeks with feedback and practice

A

motor learning

47
Q

happens over an individuals lifespan

A

motor development

48

A

T

49
Q

a PT is working with a pt teaching a quad set exercise; the pt accurately demonstrates exercise prior to leaving clinic to go home; this would indicate pt has motor learned the activity T/F

A

F

50
Q

what are the early theories of motor control

A

reflex theory, hierarchial theory, neuromaturational theory

51
Q

what are the contemporary theories of motor control

A

central pattern generators, bernstein’s circular loop theory, dynamic systems theory

52
Q

bottom up process (closed loop) where information comes in from sensory system as a stimulus and then produces a response

A

sherrington’s reflex theory

53
Q

motor behavior occurs in one way, top down approach in which motor control emerges from reflexes that are nested in the hierarchy of CNS

A

hughlings jackson’s hierarchical model of organization

A

spinal cord

55
Q

tonic reflexes - changes in posture and muscle tone

A

56
Q

righting and equilibrium reflexes

A

midbrain and cortex

57
Q

what are the 3 levels of CNS control that can override reflexes in hierarchical model

A
  • upper level: association cortex (least automatic and driving by one’s will and makes commands)
  • middle level: sensorimotor cerebral cortex (passes command on)
  • lower level: brainstem and spinal cord (carries out the action)
58
Q

normal motor development occurs as CNS develops and matures (myelinates)

A

neuromaturational theory

59
Q

in any given motor task a wide variety of neuromuscular movements may be combined in infinite ways in varying DOF

A

bernstein’s DOF problem

60
Q

proposed that the will to do a given motor behavior sets off a dynamic process

A

bernstein’s circular loop hypothesis

61
Q

movement is not based on a set pattern, but rather movement occurs as a closed loop process

A

berntein’s circular loop hypothesis

62
Q

the functional unit of motor behavior believed by Bernstein

A

syngergies

63
Q

DOF in any motor task are controlled by _____ coupling of muscle functions and joint motions into task specific functional movements in Bernsteins theories

A

synergies

64
Q

motor patterns can either be activated by a sensory stimulus or by central process within the brainstem and spinal cord knowns as

A

central pattern generators (CPG)

65

hardwired for rhythmic patterns of movement rather than only reactive, reflexive patterns

A

central motor patterns

66
Q

coordinate movement of flexor/extensor muscles within a single limb

69
Q

movement is based on dynamic interactions between task, individual and environment

A

dynamic systems theory

70
Q

reciprocal flow of information is essential if movement patterns are to be contextually adapted based on internal and external contraints; reinforces and refines motor patterns; allows us to initiate compensatory strategies if the wrong motor plan is initially selected or is unexpected environmental actions occurs

A

information processing in a dynamic system

71
Q

what are the 3 types of information processing

72
Q

specific lock-step passing of information from one part of the NS to the next (only processing one thing)

serial processing

73
Q

processing information by more than one center at a time (processing multiple things at once)

A

parallel processing

74
