Motor Feedback in Intervention

Question 1

Knowledge of Results (KR)

Answer 1

• Intrinsic (sensory info) or extrinsic (external) info about a task’s success or lack of success
• available during the task or immediately after completion of the task (or both)
• After you’ve completed the task, you know whether it’s successful or not

Question 2

Knowledge of Performance (KP)

Answer 2

-knowledge of the movement pattern(s) underlying the response

Question 3

General feedback

Answer 3

-not truly helpful especially when inappropriately given
(too frequent)
(error)

Question 4

Specific feedback

Answer 4

• Appropriate for adults

- Not appropriate for children or cognitively-involved patients

Question 5

Precision of KR

Answer 5

-The amount of accuracy contained in the feedback info

Ex) “off to the left” “too short” or “too long” Kinetics/Kinematics

Question 6

Relative Frequency of Feedback

Answer 6

100% KR (everytime) is good for immediate performance, but bad for retention

-less frequent KR is bad for immediate performance, but better for retention

Question 7

Summary KR

Answer 7

• watching

- not as good as immediate 100% KR in the performance phase, but much better for retention

Question 8

Summary vs Averaged KR

Answer 8

5 trials either summarized OR averaged appears to be optimal for retention

Question 9

Faded schedule of KR

Answer 9

gradually reducing the frequency of KR is beneficial

Question 10

Band-width KR

Answer 10

• tolerance for error around the movement goal

- correcting relatively poor performance and praising relatively good performance

Question 11

KR-delay period

Answer 11

• learner is evaluating outcome
• shortening KR-delay period is detrimental
• PT should not be talking to pt. during this period b/c it will distract them

Question 12

Post-KR delay period

Answer 12

• learner is processing KR and constructing the next movement
• shortening post-KR delay period is detrimental

Question 13

what happens if the learner is required to perform another activity during these KR periods?

Answer 13

expected to interfere or distract the learner from processing information and feedback during these KR periods

Patients must make errors, recognize that an error has been made and then correct the error in order to improve future movements

Question 14

Knowledge of Performance

Answer 14

videotape replays

kinematic feedback

kinetic feedback

-movement that produces task
