Q

Step 4

implementation/selection of assistive technologies

A

Brainstorming of Assistive Technologies begins. Activities and desired outcomes must be established and possible solutions discussed with educators, family members, physical therapist, and other people with whom the child interacts on a weekly basis. Supports should be included for movement, communication and/or use of materials if needed. Available supports in the environment should be considered first, then adaptations to those materials

Q

Hearing assistive technology systems (HATS)

A

are devices that are designed to help those with hearing disabilities function better in their day-to-day communication situations. They can be used with or without hearing aids or cochlear implants to make hearing easier and hopefully reduce stress and fatigue

Q

Lower section of linear or planar backs:

A

The lower section, which is often mounted at a 90º angle to the seat, goes up to the top of the pelvis to support a neutral pelvic tilt

23
Q

Where can secondary supports be placed?

A

laterally, anteriorly, or posteriorly to the body

24
Q

What do lateral supports do?

A

generally on the trunk

25
Q

What are hip guides for?

A

help control the pelvis

26
Q

Anterior supports:

A

used to help maintain an upright posture and topromote trunk extension and scapular retraction;

27
Q

Examples of anterior supports:

A

shoulder straps, shoulder retractors, chest straps, and vest

28
Q

Anterior pelvic support:

A

maintain the pelvis in the best functional sitting posture

Pelvic belts are the most commonly used anterior pelvic support

29
Q

Posterior supports:

A

headrests or head supports. Head supports prevent the head from falling rearward, support the head during recline or tilt, and help the client to hold his or her head upright in an aligned position

30
Q

What can neck flexion or hyperextension lead to?

A

Neck flexion or hyperextension can lead to drooling, poor swallowing, breathing impairment, and a poor visual field

31
Q

Measuring WC seat height/leg length

A

Measure from the user’s heel to the popliteal fold and add 2 inches to allow clearance of the footrest

32
Q

Average adult size of seat height/leg length:

A

19.5-20.5 inches

33
Q

How far is the bottom of the footrest from the floor?

A

2 inches

You can fit 2-3 fingers under the distal thigh (between the thigh and the seat)

34
Q

Measurement of seat depth:

A

Measure from the user’s posterior buttock, along the lateral thigh to the poplitealfold; then subtract 2 inches to avoid pressure from the front edge of the seat against the poplitealspace

35
Q

Average adult size of seat:

A

16 inches

36
Q

Measure of seat depth:

A

Can you can fit 3-4 fingers between the front edge of the seat and the patient’s poplitealfold with your palm horizontal to the seat?

37
Q

Measurement of seat width:

A

Measure the widest aspect of the user’s buttocks, hips or thighs and add 2 inches. This will provide space for bulky clothing, orthosesor clearance of trochantersfrom the armrest side panel

38
Q

Average adult size of seat width:

A

18 inches

39
Q

Hand placement for seat width

A

You should be able to place your hand between the patient’s trochanter, hip or thigh and the armrest panels with your hand positioned vertically to the seat, with slight contact to both
Both hands should be used at the same time

40
Q

Measurement of back height:

A

Measure from the seat of the chair to the floor of the axillawith the user’s shoulder flexed to 90, then subtract 4 inches. This will allow the final back height to be below the inferior angles of the scapula

41
Q

Average adult size of back height:

A

16-16.5 inches

42
Q

Location of inferior angles of scapular:

A

approx. 1 finger-breadth above the back upholstery when the patient sits with erect posture

43
Q

Measurement of armrest height:

A

Measure from the seat of the chair to the olecranonprocess with the user’s elbow flexed to 90, then add 1 inch

44
Q

Average adult size of armrest:

A

9 inches above the chair seat

45
Q

What can a seat too long cause?

A

posterior pelvic tilt

sliding out of wc

46
Q

Seat too short:

A

pressure ulcer, lack of support under femur

sliding our of seat

47
Q

Seat too wide:

A

pelvic obliquity
trunk scoliosis
feeling of instability
lateral shift or pelvis in chair

48
Q

Seat too narrow

A

pressure ulcers over greater trochanter

difficulty transferring in and out of wc

49
Q

Back too wide:

A

flexible scoliosis
lateral trunk bending
pelvic obliquity
feeling of instability

50
Q

Solution for back too wide:

A

narrower back support
lateral thoracic support
lateral pelvic support

51
Q

Back too narrow

A

lack of movement needed for function
skin breakdown on lateral trunk
discomfort caused by inability to move

52
Q

Back too low:

A

upper trunk instability; limited function
excessive thoracic kyphosis
posterior pelvic tilt

53
Q

Back too high:

A

falling forward in wc

inability to propel wc optimally

54
Q

Rear wheels too far back:

A

shoulder pain; impingement

inability to optimally propel wc

55
Q

Rear wheels too far forward:

A

wc tipping backwards; user unable to control
