Assessment Flashcards
2 good reason for testing
- Provides baseline values prior fitness program
2. A key determinant of maintaining independent living (BADL & IADL)
Direct (2 adv + 3 dis) vs Indirect method (5 adv + 1 dis)
Direct:
adv
- More accurate (3 to 5% error)
- Better estimation of desired intensity)
dis
- Required expensive and sophisticated equipment
- Higher risk for adverse events (increase stress)
- Physician supervision can be required
Indirect: adv - Easier to make measurement - Require less sophisticated equipment - Lower risks to participant - Appropriate for OA with known cardiac risk factors - Commonly used with OA dis -Less accurate (10 to 20% error)
Treadmill (5)
- Expensive
- Not portable
- Difficult taking BP
- Not appropriate for OA with balance, gait and weight problems
- Functionally relevant activity
Leg cycle ergometer (5)
- Preferred testing for people with balance, gait and weight problems
- Easier to take BP
- More portable
- Not functional exercise
- Can develop localized muscle fatigue
Recumbent Stepper (Nustep) (5)
- Preferred testing for people with balance, gait, weight and impaired motor coordination.
- Not functional exercise
- Expensive + not portable
- Difficult taking BP
- Quite recent: only 1 protocol
Arm cycle ergometer (6)
- Ideal for OA with ambulation difficulty
- Can be portable
- Relatively inexpensive
- Localized muscle fatigue ine smaller arm muscle
- Lack of functional exercise
- Difficult taking BP
What can limit the type of CRF testing for OA ?
How lower is the vo2max with leg cycle vs treadmill ?
The use of equipment rather than their aerobic fitness
10%
Why modified balke-ware treadmill test most recommended by ACSM for OA? (2)
- Use slow and constant speed (2 m/h or 3.2 km/h) and small increase in grade ( 1% per minute)
- Appropriated for OA with good ambulation (healthy), cardiac problem or chronic disease.
How can we adjust the balke-ware test for OA who are in better shape ?
- Increase speed to 2,5 or 3 m/h 4 or 4.8 km/h
- Increase grade to 2% per min
Reason stop test (9)
- Angina like-symptoms
- BP drops below 20mmHG from rest
- No increase in BP with increase in exerc intensity
- No increase in HR rate with increase in exerc intensity
- Excessive increase in SBP more 260 and DBP more 115
- Subject request to stop
- Participant show physical or verbal signs of severe fatigue
- Failure of equipment testing
- Arrythmias
What is the typical walking speed for OA and YA ?
OA = 4,5 to 4,8 km/h YA = 5,3 to 5,4 mk/h
Formula to calculate O2 consumption
0,1 x speed + 1,8 x speed x grade +3,5
where speed = m/h & grade decimal fraction (8% = 0,08)
Formula for predicted max HR for balke-ware protocole
(207 - 0,7 x age) x 0,75
Protocol 1RM briefly and steps
Avoid ? (2)
- Objectif find the max weight a person can lift once
- Use spotter
- last successful attempt = 1RM
- Only 3 to 5 cycles of adding weight
steps 1: warm up with light weights about half to predicted max
step 2: 3 to 5 reps of higher weight (60 to 80% predicted max)
step 3: small amounts of add weight 2,5-5 pds
avoid multiple reps and decrease injury
Balance is defined as ?
The ability to control the body COM relative to the BOS, whether the base is stationary or moving.
What is the limit of stability?
The max distance OA can move beyond a centered position without altering the BOS.
What are the 4 measurements of balance ?
- Static
- Dynamic
- Reactive
- Sensory integration and organisation
Static balance definition
OA have greater _____________ than YA?
Static assessment?
Force plate measure what ?
- The ability to maintain COM directly over BOS
- postural sway
- Stand still for 20-30sec, can be eyes open-closed, feet heel to toe, one legged stance.
- magnitude + velocity of postural sway
Dynamic balance definition
These tests measure? (3)
Ability to control the COM while leaning through or moving beyond the LOS
- Distance reached forward, backward, laterally, diagonally
- time of reaction
- time of accuracy
Reactive balance definition
Perturbation is elicited through a ____________ ? (3)
Ability to respond automatically to a loss of balance
Moving force plate
- Can rotate + move forward/ backward
- A participant with good balance will respond quiclky with a countermvt opposite to the direction of the plate mvt
- Force plate measure time of reaction + magnitude to the perturbation
Sensory integration & organistaion
Test measures ? (2)
Ability to integrate and organize sensory information provided by the visual, somatosensory and vestibular systems.
- How well each sensory system is functioning
- How well the participants maintains upright balance when the information coming from the 3 systems is not in agreement
