exercise testing Flashcards
why perform exercise testing
diagnois
prognose
exercise presc
treatment eval
indications for exercise testing
structural / functional limitation
factors contributing to activity limitation
does not exercise, asmpyotomic - need medical clearance
yes
exercises, asmpyotomic - need medical clearance
no - but if going vigorous yes
absolute contraindications
condition needs to stabilize first
relative contraindication
can be tested after careful eval of risk/beneftis
5 absolute contraindications
CHF Unstable Angina Uncontrolled asthma Pulmonary Edema Acute infection
5 relative contraindications
recent MI aortic valvue disease resting tacky poorly controlled dieabetes fixed rate pacemaker
how to standardize exercise test
validity and reliability
pre test conditions
explain, consent avoid heavy meal rested clothing termination criteria environment (room time, temp)
criteria for premature test termination
fatigue light headed confused ataio nausea
ECG signs
sins tacky ventricular tachy premature vent contractions Q wave shows up BP below resting
factors to consider when selecting test
cognitive age weight mobilty needs the test (valid reliable)
predictive tests
submaximal used to predict aerobic
performance tests
respond to standard PA
advantages predictive test
frequently used uses HR (easy to measure)
disadvantage for predictive test
error
variabilty
uncomfortable (biking)
12 minute run advantages
no equip
lots ppl tested
high level function ppl
12 minute run disadvantages
males developed
pacing
sounds maximal
age or body weight
20 meter shuttle advantages
stages
little equip
lots ppl tested
20 meter disadvantages
pacing
stoping starting
making sure its submax
1 mile walk advantages
wide range ppl
familiar
little equip
rehab
1 mile walk disadvantages
limited data
facility
assisntat required
modified bruce advantages
lots of data on it
can mesure ECG
disadvantaged modified bruce
treadmill safelty
special training in measuring ECG
Examples performance tests
self paces walking incremental shutte walking bag and carry time up and go harvard step 6 min walk
advantages self paced walking test
mobilty devices are ok
older people
indentfy risk of injury
disadvantages self paced walking test
doesn’t measure endurance
not sensitive for high level of function
could be too hard
how long is recovery in self paced walking test
5 min
incremental shuttle adntages
simple
slow
can help prescribe walking speed
incremental shuttle disadvantages
required near max effort
pacing
bag and carry advantages
integrated endurance balance every activity
bag and carry disadvantages
guidelines not well described
not specification step heigh handrail etc..
timed up n go advantages
easy to do
provided mobility info
disadvantages of times up n go
lack sensitivity
need data on its predictability
Harvard step test advantages
simple
can be done anywhere
disadvantages Harvard step
safety
fixed step height
whats 6 min walk test predictor of
morbidity mortality
T/f warm up for 6 minute ?
patient should be standing before?
walk with patient?
motivate them?
False
false sitting for 10
false
fasle - theres are standard phrases
what do you ask after 6 min walk test
borg
what kept you from walking further
can you perform 6 min walk twice in a day
yes 30 min rest
6 min walk test with or without aid
with
patient on or off meds during test
whatever is regular and and record it
minimally clinically importance difference
30 m
advantages 6 min walk
simple functional healthy or diseased ppl own pace tested and validated
disadvantages 6 min walk
different protocols
difficult to monitor HR
coming measures during predictive and performance tests
HR, BP sp02
