Tests and Measures

Question 1

impairments

Answer 1

ROM(joint)
flexibility(muscle)
muscle strength
cardiovascular endurance
Balance

Question 2

types of measurements

Answer 2

• unable to walk more than 20 meters before SOB
• pain when running
• function tests of balance(timed up and go; Berg balance)
• functional assessments(barthel, FIM, stair climb)
• quality of life

Question 3

factors to consider for choosing test and measure

Answer 3

1) appropriate for patient/client
2) Does it measure what it is meant to measure?(validity)
3) Is the test or measure repeatable/consistent?(reliability)
4) Cost, time to administer, practicality of the test for a given population.

Question 4

validity

Answer 4

does the test measure what it is intended to measure

- does it have appropriateness, meaningfulness, usefulness

Question 5

predicted validity

Answer 5

a test that allows one to predict ability to perform other actions

Question 6

reliability

Answer 6

• refers to amount of consistency between successive measurements when taken under same conditions
• highly reliable = little measurement error
• measurement error of +- 3.5 degrees
• at least 5 degrees for a week

Question 7

intra-tester reliability

Answer 7

often assessed by using Intraclass Correlation Coefficient(ICC)

• assesses variance between repeated measures
• performed by same tester

Question 8

inter-tester reliability

Answer 8

error of variance of measurement between different testers

Question 9

reducing measurement error

Answer 9

• maintain position of patient in measurement
• calibration of equipment
• environment
