Mobility, Disability, and Function Flashcards
Lec 4 (part 1)
What is physical function and what does it relate to?
the integration of physiological capacity and physical performance mediated by psychosocial factors. phys fxn relates to carrying out activities of daily living both basic and instrumental without risk of inury
What is the diff btwn functional independence and functional limitation?
fxnl independence is your ability to carry out ADls. fxnl limitation is a reduced ability to complete certain activities
What is disability?
limitation in performing socially defined roles and tasks expected of a person within a sociocultural and phys enviro. ex not being able to walk unassisted. Disability is a decline in fxn (but also determined by societal roles)
how are disability and frailty different?
disability is a reduction in fxn but frailty is a reduced response to an ext stressor, so instability in the syst. frailty is a predictor of disability.
how does the prevalence of disability change with age?
as increases so does the prevalence, so in OAs 65-74 its 33%, and in OAs age 75+ is 56.3%. this was with a study done in 2006 where 14.3% of canadians were considered frail. prevalence was also higher in women which could be due to many factors such as that more women live longer, or b. loss and mm mass loss.
What are the types of disability reported by OAs?
Mobility-related; unable to do locomotion, ie walking, stairs, running, carrying objects, and long periods of standin. Agility; difficulty reaching, bending, dressing, getting in and out of bed. Pain; experience long-term or reoccuring pain which limits what activities can do. more older ppl experience all 3 types of disability
What are some examples of ADL and when they are lost?
basic activities related to everyday life. dressing, personal hygiene, (early loss) transfer, locomotion, toilet use, (middle loss) eating, bed mobility (late loss)
What are some examples of IADL that are lost?
more integrative, complex activities related to ones adaptation of the environment. ie. cooking/meal prep, driving/transportation, shopping, ability to handle finances, ability to use medication, cleaning
Why are women more in need of assistance with old age then men?
could be bc of psychosocial factors or physical factors. like maybe W are more likely to ask for assistance, but could also be due to greater bone and mm mass loss.
What is mobility?
ability to locomte, so get from point a to b. either by walking, running, climbing, carrying smthn, etc. a mobility disability is when a person cant perform locomotor tasks in the usual manner. Mobility is a strong predictor of disability.
How is walking ability an indicator for mobility?
walking is determined by so many physiological systems so its an indicator for their function. (ie muskoskel., nervous, resp, etc) can asl omeasure chronic ilnesses. Gait speed test is 2m long and determines that if your walking speed is slower then 0.8m/s you are at risk for disability/ have poor mobility. more then 1m/s is good. can determine this by measuring; 1. walking speed (4-8m) 2. time to walk (400m), 3. self-report walking ability (1/4 mile)
What are some factors associated with lower mobility on OAs?
low SES, low education, women more affected by age, # and type of chronic illnesses, chronic and sensory impairments.
What is optimal mobility?
being able to safely and reliably go where you want, how you want, and when you want. so being able to locomote in various ways. especially bc walking and driving are primary ways to get around
What is the difference btwn autonomy and independence?
autonomy is being able to make decisions. independence is being able to do the task you’ve already decided on your own.
How does automobile dependency affect OAs?
if oas can drive they are more likely to go out. so with lack of transportation options like driving themselves, they are more likely to stay home at any given day. older non-drivers take 15% less trips to the dr.s and 65% less trips for recreation and social activities.
