Module 1 chapter 2

Question 1

Categories of performance

Answer 1

Outcome: speed, distance but doesn’t describe the movements or activity of muscles
Production: performance characteristics to achieve outcome, kinematices, force, EMG

Question 2

Reaction time

Answer 2

RT length of time to prepare and initiate a movement (time of stimulus to reaction)

Question 3

Movement time

Answer 3

The amount of time it takes when initiated to completion MT

Question 4

RT + MT = ?

Answer 4

Response time

Question 5

Simple, choice and discrimination are ?

Answer 5

Types of reaction time

Question 6

Simple reaction time

Answer 6

1 signal, 1 response

Question 7

Choice reaction time

Answer 7

1 signal, each signal with specified response

Question 8

Discrimination

Answer 8

1 signal , only 1 response (red blue and green and only supposed to put the button when a certain color appears)

Question 9

Spatial accuracy, temporal accuracy are components of ?

Answer 9

Error measures

Question 10

Error measures indicate accuracy, a problem with consistency may mean

Answer 10

Basic movement pattern has not been acquired

Question 11

Error measures indicate accuracy, a problem with bias may mean

Answer 11

Basic movement pattern has been acquired, but adaptation to task demands has not been acquired

Question 12

One dimensional error measures

Answer 12

Absolute error AE
Absolute difference between actual performance on each rep and goal
Magnitude of error, general index of accuracy
Constant error CE
Signed deviation from target (+-), amount and direction _ walk at a certain speed and are always over or under
Tendency to over or undershoot goal
Variable error VE
Amount of variability in the performance

Question 13

VE vs CE

Answer 13

Marks all over the target vs one general area on target

Question 14

Kinematic measures

Answer 14

Motion description without regard to force
Describe characteristics of critical components of skill during movement
Displacement, velocity and acceleration
-marks joints or track person moving object
-linear motion = in a straight line; whole all body/object moves same distance over same time
-angular motion (rotary motion) = occurs about axis of rotation

Question 15

Kinetics

Answer 15

Consideration of FORCE in study of movement
Force as a cause of motion, force plates, force transducers, strain gauges

Question 16

Measuring coordination

Answer 16

Analyze limbs/limb segments in time and space
-cross correlation technique (relationship between 2 joints at a specific time point, correlation coefficient means extent to which 2 joints follow similar movement patterns

Question 17

Cross correlation technique

Answer 17

Relationship between 2 joints at a specific time point

Question 18

Correlation coefficient

Answer 18

A component of measuring coordination by cross correlation technique, correlation coefficient is extent to which 2 joints follow similar movement patterns

Question 19

Clinical applications for measurement

Answer 19

Assessment and targeted treatment planning
Measure the outcome, movement or neurological basis for outcome
Different measures offer different information
