27
Q

characteristics of self propelling wheelchairs

A

Tthe chairs have either
– a fixed or rigid frame
– or ‘folding frame’
• Big wheels at the rear, and small wheels at the front to enable the user to push the chair
• In general, fixed frame chairs are easier to push and more sturdy, but unable to fold, and folding chairs have more apparatus and are heavier to push, but more convenient for storage.
• *require good upper limb strength
• *can alter every component of wheelchair for the specific person.
• *no arm rests are for more active people

28
Q

high performance wheelchairs

A
  • Users with increased level of indoor and outdoor independence
  • Standard equipment doesn’t meet lifestyle needs
29
Q

attendent propelled wheelchair

A
  • Used by people who are unable to push themselves, and include buggies or pushchairs for younger users, as well as wheelchairs that are purely for someone else to push.
  • This type of chair tends to have small wheels at the back and the front, and is an essential back up if the person uses a powered wheelchair as their main form of independent mobility
30
Q

special types of mobility systems

A
  • Children’s wheelchairs and buggies
  • High performance sports wheelchairs
  • Bariatric wheelchairs
  • Stand up wheelchairs
  • Elevating wheelchairs
31
Q

seat angle

A
  • Change by changing height if axle plate
  • Changing caster or fork size
  • Can add stability to user
  • Too little can make person fall forward
  • Too much can increase pressure on sacrum
  • Too much can make it difficult to bring bottom forward
  • **Tilt backwards for someone who finds it difficult to sit up straight against gravity
32
Q

setting up wheelchair

A

Position of axle affects balance and stability

  • When wheels are moved forward of axle, more of the weight is behind the axle, therefore the chair is more tippy, but also more inefficient propulsion
  • Whereas if wheels are moved in front of axle, chair more likely to tip person out the front
  • Position is process of trial and error, depends on person’s strength and skills
33
Q

key role of pelvis in seating

A
  • Joins spinal column and lower limbs
  • Supports body in sitting
  • Moves backwards and forwards as we perform activities
Normal sitting;
•	Pelvis in slight anterior tilt 
•	Weight taken evenly through both ITs 
•	Good for function 
•	Sacrum supports no body weight
34
Q

whats posterior pelvic tilt

A 
•	Sacral sitting’ 
•	Common when sitting for long periods 
•	Most dangerous 
•	Associated with sacral, heel & spine pressure ulcers
(arching back head forwards)
35
Q

whats pelvic obliquity

A
  • Common when sitting for long period
  • Caused by instability of chair or person
  • Weight taken through one IT - risk of ulcers
  • Associated with scoliosis
36
Q

whats shear force

A

is parallel or tangential to the face of the material (in this case skin). Shear force causes rubbing of the skin over the bone (think blisters from uncomfortable shoes). This leads to sores, which, combined with compression leads to pressure injuries.

37
Q

factor affecting wheelchair assessment

A
  • Client
  • Carer
  • Environment
  • Personal choice
38
Q

client assessment considerations

  • Perception
39
Q

  • Access eg narrow doorways and hallways, steps, stairs, ramps, turning space, worktop heights, height of through floor lift
  • Transport of chair
  • Terrain – driveway
  • Storage
41
Q

personal choice

A
  • Lifestyle, work
  • Recreation, hobbies
  • Finance
  • Aesthetic values
  • Personal choice
42
Q

whats the mechanical assessment tool assessment (MAT Tool)

A

Mechanical Assessment Tool assessment widely considered “good” or “current best” practice
– Provides clinical evidence for decisions
– Provides measurements which form a basis for intervention (product selection, customisation)
Assesses
– Joint ROM, sitting posture, balance, tone, muscle strength, coordination, endurance
– Body / anthropometric measurements (linear & angular) Measurement for seating:
- *Important role of Occupational Therapist
- Correct measurement of chair or wheelchair is essential in order to:
- Provide good positioning
- Provide comfort
- Prevent increased pressure in susceptible areas

43
Q

other integlral parts of mat assessment

A 
Sensory Impairments 
-	Paralysis 
-	Neuropathy
Developmental/Cognitive Level 
-	Able to identify sore areas? 
Other orthoses, devices that are used 
-	Do they interfere with position 
Nutrition 
-	Malnourished? 
-	 Bariatric
Risk of Pressure
44
Q

basic seating measurements

A
  • A - widest measure across the hips
  • B - rear of the buttocks to the inside of the bent knee
  • C -Bottom of the heel to the inside of the bent knee
  • D - Seat to Scapula
  • E - Seat to Top of Shoulder
  • F - Seat to Top of Head
45
Q

whats a pressure injury

A

Pressure injury: is a localised injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear and/or friction.

46
Q

whats the ASIS scale

A

used to define and describe the extend an d severity of a patient’s spinal cord injury and help to determine rehabilitation and recovery needs.

47
Q

whats the there main parts of the ASIS test

A
  • Manual Muscling testing
  • Light touch sensation
  • Pinprick sensation
48
Q

when is the ASIS scale used

A

It is ideally completed within 72 hours after the initial injury. T

49
Q

mental health affects from spinal cord injury

A 
Depression:
- longer hospitalisations 
- fewer functional improvements 
- greater pressure ulcer occurrence 
- poorer subjective health 
- higher medical expenses 
Anxiety:
- excessive worry
- social anxiety
Post traumatic stress disorder:
- flashbacks/nightmears
50
Q

acute care for spinal cord injury

A

Successful acute care management is dependent upon excellent positioning and extraordinary attention to regular and correct turning.
The primary aim of positioning is to support the injured spine in a good healing position.
Secondarily, the aim is to maintain limbs and joints in a functional position, hence reducing the incidence of spasticity and preventing contractures and deformity.
Other aspects of concerns may include psychological care, range of motion, respiratory care and pressure sore prevention.

Most (more than 50 percent) of the muscles that are spared below the level of injury are strong enough to move against gravity.
Grade E
All neurologic function has returned.

64
Q

whats the two types of paralysis

A

flaccid paralysis

spastic paralysis

65
