Q

What are the benefits of the recumbent stepper? (2)

A
  1. Better for OA with balance, gait, or weight issues
  2. Better for OA with imparted motor coordination (stroke, parkinsons)
18
Q

What are the disadvantages of the recumbent stepper?

A
  1. Not functional
  2. Expensive and not portable
  3. Difficult to take BP during test
  4. Recent = limited exercise protocols for testing
19
Q

What are the benefits of the arm cycle ergometer?

A
  1. Idea for OA with ambulatory difficulty (wheelchair, stroke, etc. )
  2. Can be portable
  3. Relatively inexpensive
20
Q

What are the disadvantages of the arm cycle ergometer?

A
  1. Localized muscle fatigue in smaller arm muscles
  2. Lack of functional specificity
  3. Difficult to take BP during test
21
Q

How many protocols are there for the recumbent stepper?

A

1

22
Q

What percent of max age-predicted HR must OA reach in a submax exercise test?

A

+/- 75%

23
Q

What is the basis for predicting VO2 max with a submax test?

A

That HR will increase linearly (at the same rate) as VO2 max

24
Q

What is the Modified Balke -Ware test?

A

A slow and constant walking speed with small increases in grade every minute (about 1%)

25
Q

T/F: The mod. Balke-Ware test is best for OA with good ambulation?

A

True

26
Q

T/F: The mod. Balke-ware test has never been used for stroke or Parkinsons.

A

False, it can be successful

27
Q

What are two ways to modify the Balke-Ware test?

A
  1. Increase walking speed
  2. Increase grade increments
28
Q

Reasons for stopping the Balke-Ware test? (15+)

A

-angina
-OA not sweating
-lightheadedness
-confusion, unsteadyness
-palor
-blue lips
-BP drops from rest
-no increase in systolic BP with increased intensity
-excessive rise in systolic BP
-HR dies not rise
-change in heart rhythm
-participant requests to stop
-physical or verbal signs of severe fatigue
-failure of testing equipment

29
Q

What is considered and excessive rise in BP

A

Over 260 in systolic or over 115 in diastolic

30
Q

How low is too low for a BP to drop from rest during exercise?

A

20mmHg

31
Q

What is the typical walking speed of OA?

A

4.5-4.8 km/hr

32
Q

What is the prediction equation for the treadmill test?

A

(0.1speed)+(1.8 speed* grade) +3.5

33
Q

What unit should speed be in?

A

Meters/min

34
Q

What is the conversion of mile/hour to meter/min?

A

1 mile/h = 26.8 m/min

35
Q

How many cycles of adding weight are recommended for 1RM testing?

A

3-5

36
Q

What are the 4 measurements of balance?

A
  1. Static
  2. Dynamic
  3. Reactive
  4. Sensory integration and organization
37
Q

What is static balance?

A

The ability to maintain the Center of Mass directly over the base of support.

38
Q

What do dynamic stability tests measure?

A
  1. Distance reached (A-P, M-L, diagonally)
  2. time of reaction
  3. movement accuracy
39
Q

What do force plates measure?

A

Time + magnitude of reaction to perturbation

40
Q

What is sensory integration and organization?

A

Ability to integrate and organize sensory information provided by visual, somatosensory, and vestibular systems.
