Tests and Measures Flashcards
impairments
ROM(joint) flexibility(muscle) muscle strength cardiovascular endurance Balance
types of measurements
- 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
factors to consider for choosing test and measure
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.
validity
does the test measure what it is intended to measure
- does it have appropriateness, meaningfulness, usefulness
predicted validity
a test that allows one to predict ability to perform other actions
reliability
- 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
intra-tester reliability
often assessed by using Intraclass Correlation Coefficient(ICC)
- assesses variance between repeated measures
- performed by same tester
inter-tester reliability
error of variance of measurement between different testers
reducing measurement error
- maintain position of patient in measurement
- calibration of equipment
- environment
