Age, Frailty and Sarcopenia Flashcards
Sarcopenia
Skeletal muscle loss
poor muscle quality
frailty
a syndrome of decreased reserve and resistance to stressors that result in cumulative declines across multiple physiologic systems causing heightened vulnerability to adverse outcomes
what is frailty such a problem?
it has increased risk factors and poor outcomes across disease states and health care interventions
in what areas can PT impact in the cycle of frailty?
- sarcopenia
- decreased strength and power
- decreased vo2 max
- decreased walking speed
- decreased activity
what is the impact of frailty in acute care and ICU
decreased HRQOL
delirium
increased falls
greater debility
institutionalization
why is measurement of frailty important?
predicts:
falls
ED visits
entry into residential care
survival rate
in the elderly better health care results in longer life but not _____
higher health care cost
What are the frailty phenotype components (5) greater than 3 of these indicates frailty
- shrinking- >10 lbs
- self reported exhaustion
- weakness (decreased grip strength)
- slow walking speed
- low physical activity
what is the cutoff for walk speed
about >7 sec for 10m walk test
gait speed of ____ or higher consistently demonstrated survival that was longer than expected by age and sex along
1.0 m/s
why would gait speed predict survival?
integrates alot of different body systems
the degenerative loss (atrophy) of skeletal muscle mass, loss of muscle quality and loss of strength associated with aging
fat in muscles
sarcopenia
sarcopenia is a component of _____ syndrome
frailty
decreased muscle quality in older adults is correlated with _____.
reduced force production
Can 12 weeks of resistance training improve patient strength even in older age
yes
