1
Q

Define Motor Control.

A

The study of the nature of movement; or the ability to regulate or direct essential movement

Historically though to arise from reflex or hierarchical models where the cortex was perceived as the highest functioning component of the system and spinal level reflexes were the lowest functioning components

Q

What does Motor Learning differentiate?

A

Differentiates learning vs performance, provides guidelines for appropriate use of feedback, prioritizes the impact of practice as it relates to skill and movement, and also focuses on the transfer of learning across tasks and environments of practice.

Q

What is the autonomous stage characterized by?

A
  1. automatic response
    - mainly error-free regardless of the environment
    - patterns of movement are non-cognitive and automatic
    - distraction does not impact the activity
    - the person can simultaneously perform more than one task If needed
    - extrinsic Feedback should be very limited or should not be provided
    - internal feedback or self-assessment should be dominant

Q

Why is feedback important?

A
  • It is imperative for the progression of motor learning.
  • Allows for correction and adaptation within the environment
  • Pts will rely on both intrinsic and extrinsic feedback

Q

List the types of feedback

A
  1. Intrinsic (inherent) FB
  2. Extrinsic (augmented) FB
  3. Knowledge of results (KR)
  4. Knowledge of performance (KP)
24
Q

Describe Intrinsic (inherent) FB.

A
  • represents all FB that comes to the person through sensory systems as a result of the movement.
  • Includes: visual, vestibular, proprioceptive, and somatosensory inputs
25
Q

Describe extrinsic (augmented) FB.

A
  • represents the information that can be provided while a task or movement is in progress or subsequent to the movement
  • typically in the form of verbal FB or manual contacts
26
Q

Describe KR.

A
  • important form of extrinsic FB

- includes: terminal FB regarding the outcome of a movement that has been performed in relation to the movement’s goals

27
Q

Describe KP

A

Extrinsic FB that relates to the actual movement pattern that someone used to achieve their goal of movement

28
Q

In NeuroRehab what does practice refer to?

A

Repeated performance of an activity in order to learn or perfect a skill

29
Q

What does practice allow?

A

Allows for direct physical experience and kinesthetic stimulation to assist with acquisition of the skill

30

What is mental practice?

A

Cognitive rehearsal of a task or experience without any physical movement

32
Q

Massed Practice

A

The practice time in a trial > the amount of rest b/t trials

33
Q

Distributed practice

A

The amount of rest time b/t trials is =/> the amount of practice time for each trial

34

39
Q

Part training

A

Practice of an individual component or selected components of a task

40
Q

Closed System model

A
  • characterized by transfers of information that incorporates multiple FB loops and larger distribution of control
  • the NS is seen as an active “participant” with the ability to enable the initiation of the movement as opposed to solely “reacting” to stimuli
41
Q

Compensation

A

Ability to utilize alternate motor and sensory strategies due to an impairment tha limits the normal completion of a task

42
Q

Habituation

A

Decrease in response that will occur as a result of consistent exposure to non-painful stimuli

43
Q

Learning

A

The process of acquiring knowledge about the world that leads to relatively permanent change in a person’s capability to perform a skilled action

44
Q

Types of learning

A
  1. Non-associative
    2 associative
  2. Procedural
  3. Declarative
45
Q

Non-associative Learning

A

A single repeated stimulus (habituation, sensitization)

46
Q

Associative Learning

A

Gaining understanding of the relationship b/t two stimuli, causal relationships or stimulus and consequence (classical conditions, operant conditioning)

47
Q

Procedural Learning

A
  • Learning tasks that can be performed without attention or concentration to the task
  • A task is learned by forming movement habits (developing a habit through repetitive practice)
48
Q

Declarative Learning

A

Requires attention, awareness, and reflection in order to attain knowledge that can be consciously recalled (mental practice)

49
Q

Motor learning

A
  • ability to perform a movement as a result of internal processes that interact with the environment and provide a consistent strategy to generate the correct movement.
  • acquisition of, or modification of movement
50
Q

Motor program

A
  • concept of a central motor pattern that can be activated by sensory stimuli or central processes.
  • motor programs are seen as contains the rules for creating spatial and temporal patterns of motor activity needed to carry out a given motor task
51
Q

Open system model

A
  • characterized by a single transfer of information w/o any FB loop (reflexive hierarchical theory)
  • in theory, the NS is seen as awaiting stimuli in order to react
52
Q

Performance

A
  • temporary change in motor behavior seen during a particular session of practice that is a result of many variables, however, only one variable is focusing on the act of learning.
  • Performance is not an absolute measure of learning since there are multiple variables that potentially affect performance
53
Q

Plasticity

A

-ability to modify or change at the synapse level either temporarily or permanently in order to perform a particular function

54
Q

Plasticity

A

-ability of the motor and sensory systems to stabilize position and control movment

55
Q

Recovery

A

-ability to utilize pervious strategies to return to the same level of functioning

56
Q

Sensitization

A

The increase in response that will occur as a result of a noxious stimuli

57
Q

Strategy

A

A plan used to produce a specific result or outcome that will influence the structure or system
