Functional Capacity Assesment of Geriatric

Question 1

How does better aerobic capacity/fitness affect cardiovascular disease?

Answer 1

Higher fitness= less mortality and incidence of disease

MET levels > 7.9 had less mortal events
-low aerob fitness 10.8

Question 2

Fall Risk Stratification criteria for older adults

Answer 2

Fall History- 8 points
Live alone- 3 points
Female- 3 points
4 or more meds- 3 points

Low risk: 0-4
Mod risk: 5-10
High risk: 11-16

Question 3

What does Living Space Mobility Assesment test? What are the categories?

Answer 3

On scale 0-120 assess functional capacity in older adults
Multiplies:
A) Location: 
-bedroom: 0
-home: 1
-outer house: 2
-neighborhood: 3
-town: 4
-unlimited: 5
B) How often: 1-7 day/week
C) Assertive device 

Healthy older adult= 100 points
High risk disability and decreased aerobic capacity

Question 4

What is the Duke Activity Status Index used for?

Answer 4

Measures functional capacity via 12 y or n questions
Estimates VO2 peak (up to 34 or 9.8 METS)
[0.43xDASI]+9.6

Min capacity needed for Functional Independence
M: 18 mL/kg/min = 5.14 METS
F: 15 mL/kg/min = 4.3 METS

Question 5

How is the DASI Tested?

Answer 5

Ask yes or no questions
ex: walk indoors? light housework? sexual relations?
yes= no difficulty performing

(Asistive device okay to use!)

Question 6

What is the Short Physical Performance Battery?

Answer 6

3 Sub-tests with total 12 points measuring balance, gait, and strength

1. Static standing balance: rhomberg then tandem
2. Gait speed via 4M walk
3. 5 Time S-toS

Question 7

What is the Risk Stratification for Gait Speed?

Question 8

How does aging affect Gait and VO2?

Answer 8

Aerobic capacity decreases as well as LE strength resulting in higher RPE and slower gait speeds

• lose 86% VO2 from decreased muscle mass and mitochondrial function
• sarcopenia and mass loss contributes

Question 9

3 Risk Factors for Disability in new CHF patients

Answer 9

cognitive impairements
depressive sx
gait speed

Question 10

Five time Sit-to-Stand Norms

Answer 10

Age 60-69: 11.4s
Age 70-79: 12.6s
Age 80-89: 14.8s

> 15s= 2x incidence of falls!!

Question 11

What is the Prognostic Value for the SPPB regarding hospitalization and MCID?

Answer 11

Scores 0-4= 5x increased risk of hospital/death
Scores 5-7= 2.6x increase risk hospital/death

1 point increase results in 14% less risk

MCID: 1-2 points
-muscular power associated with meaningful change in SPPB and gait speed
