Q

what are 4 goals of a seating system

A
  1. extrinsically duplicate waht is intrinsically impaired w/i the patient
  2. provide proximal stability to enable distal mobility
  3. restore “normal” seated posture without restricting function
  4. maximize pressure distribution to prevent tissue trauma

  1. loss of strength, inc ms tone, etc.
  2. give them a stable base

Q

how does the axle being further back vs further forward change mobility in a manual wc

A

further back - more stable, less responsive, wider turn radius, more effort needed
* B LE amps COM’s will be further back, so need the axle further back

further forward (under COG) - more responsive, tighter turns radius, better alignment for shoulders to propel
* less shoulder strain and better redistribution of wt

* pts who have to travel under time constraint (college students)

29
Q

smart drive

what is it and why does it slay

A

creates “cruise control”
clamp that you can drop on so you can be hands off and only have to do course corrections
* works up and down curbs bc will flex w you
* intuitive system - will stop the second you brake

30
Q

what is required to be able to navigate the controller of a power wc (2)

A

consistent volitional mvmt
cognitive capacity

31
Q

what is the justification for a power wc

A

cannot propel any wt or configured manual wc because…

have to r/o less costly manual wc - give reason why they can’t propel manual wc even the custom fit ones

32
Q

what are 4 criteria for funding any powered mobility device

A
  1. unable to accomplish MRADLs safely in home
  2. can’t accomplish MRADLs in reasonable amt of time
  3. limitations not resolved by cane or walker
  4. limitations not resolved by optimally configured manual wc

MRADLs = mobility related ADLs

33
Q

5 considerations in a pt for a power operated vehicle (POV)

A
  • meets PMD criteria
  • can transfer to/from
  • can maintain postural control while operating
  • home is accessible
  • 2 functioning UE to operate the tiller
34
Q

who does she usually see as a good candidate for a POV

A

someone in a nursing home:
* don’t have endurance for longer walking distances
* nursing home w those distance, medicare would cover bc “in the home”

35
Q

6 considerations in a pt for all power wc (PWC)

A
  • needs to exceed criteria for POV
  • established ability to safely operate
  • home is accessible
  • PWC sig improves MRADLs
  • pt willing and able
  • pt within weight requirements

think ab visual acuity (ie neglect) and cog ability to operate PWC
home needs to be accessible bc so heavy

36
Q

what are the 2 main things that r/o a POV for a pt and elevates it to a PWC

A
  • UE needs
  • postural control
37
Q

PWC: group 1

1 pro, 2 cons

A

pro: small enough turning radius for home use (unlike POV)

cons:

PWCs

if your pt needs/depends on tilt/recline functions for skin breakdown prevention or pressure redistribution, what group do you jump to

A

3

40
Q

PWC: group 3

what is the needed justification

A

need ATP involvement
qualifying dx

ATP = assistive tech professional

41
Q

PWC: group 3

why does the programming capability of this group slay so much

A
  • if they have a tremor - can talk to controller to disregard tremor and keep course straight
  • if they have hand weakness - can adjust throw of joystick so more sensitive
42
Q

PWC: group 3

4 pros

A
  • higher speeds
  • improved battery life for all day use
  • programming capability
  • power seat functions (can add tilt/recline)

what 3 characteristics separates this from group 3

A
  • no compromises (ant tilt, full post tilt)
  • improves suspension
  • standing/power seat elevation
44
Q

PWC: group 4

how can you justify a chair in this group

A

physiologic/psych benefits of standing as well as function in the home

45
Q

PWC: group 5

3 characteristics

A
  • pediatric
  • designed w growth in mind
  • pt weighs <125#
46
Q

PWC: group 5

how can you justify this

A

to keep up w their peers’ function/ mobility at school, etc.

47
Q

rear wheel drive

turns, speeds

A

larger turning radius
* so much of wc frame in front of wheel to turn

higher speeds

all that was available at first

48
Q

midwheel drive

turns

A

very tight turning radius

made a huge difference environmentally w turns

49
Q

midwheel drive

what is a consideration in pts w spasticity and tone

A

may say they feel like they can feel the bumps in this chair
* even tho the suspensions are pretty good

50
Q

midwheel drive

location of center and why is this relevant

A

high center
* if caught, front casters can get up but midwheels can’t catch anything to propel forwards

51
Q

front wheel drive

turns, obstacle navigation

A

larger turning radius than midwheel (smaller than rear wheel)
* handles 90deg turns in home better than midwheel

can climb over obstacles
* drive wheels in front of chair and can pull chair along
* front casters don’t get in the way

52
Q

what is the more intuitive drive configuration in PWCs

A

front wheel

53
Q

what is a good thing to ask in PMH when prescribing a wc and why

A

upcoming surgeries
* can structurally alter what they look like which changes the needs of the chair

54
Q

why do we care ab the pt’s social hx (beyond the obvious of helping us have a good recommendation)

A

can paint the picture of a personal touch in letter of medical necessity
* include what person wants to do w seating system

55
Q

what are 10 things to ask about in the PMH

A
  1. CC
  2. age
  3. height and weight
  4. dx

clinical exam

what 3 things do you screen in your CVP screen

A
  • cardiac limitations (CHF)
  • respiratory problems (COPD)
  • circulation (PVD)
61
Q

why is it significant to assess for respiratory problems

A

postural ms help w breathing, in pts w cardiopulm problems their posture will be sacrificed so those ms can help pt breathe

62
Q

clinical exam

how can better posture help the respiratory system

A

deeper breathing and respiration

can also help w hypophonia in PD

63
Q

clinical exam

what are 4 things to screen as part of your integ systems screen

  • protective measures (tilt and recline, pressure redistribution)
  • general care (clean/dry)
64
Q

clinical exam

where is it common for pts to get skin breakdown? and how does posture contribute?

A

pts commonly sit in post pelvic tilt
* breakdown over sacrum
* if asymmetrical pull, ITs are next

65
Q

what factor is a huge contributer to pressure ulcers beyond just the amt of pressure

A

moisture

cushions today sometimes have airflow tech to mitigate moisture building up

66
Q

clinical exam

what are 5 things to assess in your functional exam
