When testing OA (vs. YA), which physical parameter (s) should we focus on and why?
Strength and mobility to prevent sarcopenia and prevent fall
-> Most important one is strength training
Performing Assessments will help you:
- Help _ if a participant is at risk for mobility problems & disability
- Determine if the _
is appropriate for the older
exercising population - _ your participants to set personal goals
- _ that meet specific needs of older participants
- provide meaningful _ to participants
- document the _ of your physical activity program
- identify and predict
- program
- motivate
- select exercise
- feedback
- benefit
what is a physical impairement
loss or abnormality at the tissue, organ or body system level
what is a functional limitation
restriction in physical behavior such as rising from a chair, lifting or climbing stairs
what is a physical disability
any restriction or lack of ability to perform a task or an activity in the Lanner considered normal
functional fitness framework objectif
-Identifies physical fitness parameters associated with functional mobility
- Relates functional mobility to ability and active daily living
role of quadricep strength in functional fitness of OA
increase strength = increase stair climbing= increase ADL
The time to peak torqued of quad show what
significant correlation with all measure of physical activity test
does isometric and isokinetic torqued had significant correlation with any of the physical activity
no
what does the study of quad strength vs function in OA show
time to peak torque was the best variable (strongest correlation with climbing stairs) so those able to contract their quad faster were the best at climbing stair -> show strong correlation with quad strength
Common Obstacles with Assessments of OA
- Lack of time ,space and budget
- Lack of trained personel
Either administering test or interpreting test - Lack of assessment tools
- Absence of a requirement by facility management
Are most PA centers for OA good at conducting field-based assessments
yes for assessment but not for follow-up
major criteria for selection & evaluation of test instruments
- praticality
- psychometric proprieties
what is practicality
usability of a test
factor that influence practicality
- Medical permission or supervision required and available (ex: Exercise Stress Test)
- Time needed to administer and score the test
- Personnel and expertise needed to administer test
- Level of fatigue to participant per test
- Is the test meaningful to your participants?
what is psychometric proprieties and what are the 4
Refers to the degree the test will meet specific and established test construction guidelines
Reliability
Validity
Discrimination Power
Performance standards
what is reliability
Refers to the degree that two test scores are similar when tested under identical conditions
Test would then be free of measurement error Referred to as “Test-Re-Test Reliability”
reliability of a test should be >_
0.80
score that are reliable must originate from where
a published protocol
what is inter-rater reliability
When scores obtained from multiple testers are very similar
High correlation
what is validity
Refers to the test having shown to measure what it’s intended to measure
what is the most important characteristic of any test
validity
what is criterion-related validity
Evaluates a test’s validity by comparing its scores with other scores already found to be valid
acceptable correlation value of criterion-related validity
> 0.70
