Flashcards in Measurement of Motor Learning and Performance AEP Deck (47):
1

Concept map: appropriate measurement of motor performance in clinical rehabilitation is necessary to provide a quantitative basis for:

• assessing motor capabilities and limitations
• determining the locus or source of performance limitations
• providing evidence that skill improvement results from your chosen interventions

2

Points of emphasis (of a concept map) #1 =

learning-performance distinction

3

Points of emphasis (of a concept map) #2 =-

performance measures
-outcomes
- production

4

Points of emphasis (of a concept map) #3=

error measurement

5

Points of emphasis (of a concept map) #4=

tests of learning
- retention
- transfer

6

Learning-performance distinction involves what 2 types of characteristics?

performance characteristics and
learning characteristics

7

List 4 performance characteristics:

1. outcome of executing a motor task
2. directly observable or measurable
3. temporary in nature
4. fluctuates in accord with variable that do not affect learning

8

Learning characteristics =

1. not directly observable
2. inferred from performance
3. results from practice
4. relatively permanent change in capacity to perform a given skill

9

If performance is variable, how can we infer that learning has occurred?
1. persistent ___________________
2. increased _____________________
3. stability of _________________
4. ____________________
5. Reduction of ___________________ demand

1. persistent improvement
2. increased consistency
3. stability of performance
4. Adaptability
5. Reduction of attentional demand

10

stability of performance =

performance is stable even with disruptions or changes in external or internal conditions

11

Adaptability =

can apply learned skills in different contexts

12

As a clinician my task is to:

- identify the key features of a skill
- prioritize the performance characteristics most necessary to function in the given environment
- measure the key performance characteristics that indicate the level of mastery and progress

13

Name 2 types of performance measures:

1. outcome measures
2. production measures

14

outcome measures =

indicate the result of performing a motor skill, such as

15

list examples of outcome measures:

• distance walked
• speed of a thrown ball
• distance from a target
• number of successful shots on goal
• gait speed

16

Do outcome measures give info about movements of the head, limbs or body?

no

17

Time to complete a task, # of trials to completion, #/% of errors, time on/off target, time on/off balance, magnitude of error in performing a movement, consistency of errors are all examples of what type of performance measure?

outcome

18

Production measures =

measures characteristics of the movement that produced the outcome

19

The benefit of performance measure is that they can provide information about:

• muscular activity
• limb interaction before/during/ and after a skill
• nervous system function

20

3 performance production measures are:

1. biomechanical measures
2. electromyography (EMG)
3. Brain activity

21

Biomechanical measures involve:

kinematics --> movement
and kinetics -->force

22

Kinematics involve:

• displacement (spatial position)
• velocity (speed)
• acceleration (change in velocity)
• joint angle / limb position

23

kinetics involve:

• joint torque (force * distance)
• ground reaction forces

24

Electromyography (EMG) involves timing of onset of __________ activation, muscle timing ______________ and relative _____________.

onset of MUSCLE activation, muscle timing COORDINATION, and RELATIVE activation

25

Brain activity can be recorded by:

• fMRI
• EEG
• positron emission tomography (PET)
• rCBF

26

Error measurement =

nearly all skilled task performance requires some level of task accuracy

27

Evaluation of pt performance relative to the goals of task mastery is crucial to document progress towards and achievement of:

goals in the medical record

28

Error measurement can reveal patterns of change in performance to customize:

interventions

29

Name the 3 types of error measurement?

1. Absolute error (AE)
2. Constant error (CE)
3. Variable error (VE)

30

absolute error is defined as =

average difference between the measured value and the criterion value over a given number of trials

31

Absolute error =

criterion score minus actual score (regardless of direction or algebraic sign)

(criterion score - actual score) = Xn

AE = IX1I + IX2I + IX3I + ... / #trials

32

constant error (CE) =

average error over a given number of trials

33

Constant error is based on both:

magnitude and direction

34

Constant error provides a measure or response:

bias

35

(45, 40, 35, 35, 30) --> (+5, +0, -5, -5 ,-10) ; Mean CE =

mean CE = (-15)/5 = -3

36

Variable error (VE) =

measure of consistency or response, not the amount of erro

37

Variable error is calculated as the standard deviation of error around an individual's:

average performance

38

Retention =

measures persistence or relative performance of performance improvement

39

The assessment of performance of the same skill under the _____________________ over time

same conditions

40

Retention involves a skill that is retested after a period of no practice with no:

feeback

41

Retention reflects the strength of the _______________________ representation created during the learning process

motor memory

42

Transfer =

measures the adaptability of a skill under different conditions

43

transfer of novel contexts =

physical environment or feedback changes

44

transfer of novel skill variation=

fast vs slow, different object manipulation

45

Transfer gives information about the extent to which a learner may perform in a _____________________.

different situation

46

Transfer reflects the _________________ of the motor memory.

flexibility

47

Transfer is important when skill learned must be performed:

across a variety of conditions
