1
Q

What does ASIA stand for?

A

American Spinal Injury Association

2
Q

What are the levels scored in the ASIA examination

A
C2 to S4-5
The pinpricks are measured on a 0-2
0: absent
1: impaired
2: normal
3
Q

how do you classify a person as an incomplete SCI?

A

Partial preservation of sensory and motor function is found below the neurological level and must include the lowest sacral segment

4
Q

How do you classify a person as complete SCI?

A

He or she has no sensory or motor function inthe lowest sacral segment.

5
Q

What are some possible complications in children with SCI?

A

Hip dislocation/subluxation
Scoliosis
Pressure ulcers

6
Q

What are the different walking patterns seen in patients with SCI?

A

Step to
Step through
Swing to
Swing through

7
Q

For a patient with SCI using an Floor reaction or Ground reactionAFO, what muscles must be present?

A

Hip flexion

quad strength of 4/5

8
Q

For a patient with SCI using an articulated AFO, what muscles must be present?

A

Hip flexion
Quad strength of 4/5
Knee strength

9
Q

What muscle strength is absent for a patient with SCI to use a KAFO?

A

Quads

10
Q

What is parastance?

A

The most stable stance involving neutral ankle
Knee in extension
Hips in passive extension

11
Q

Why would a patient with SCI require a HKAFO?

A

The level of injury is higher
Hip flexion, knee flexion, or ankle plantarflexion contractures,
Poor balance
Decreased motor control.

12
Q

What are HGO ORLAU parawalkers?

A

Hip Guidance Orthosis
Orthotic Research and Locomotor Assessment Unit (ORLAU) parawalker
Theses are HKAFOs with free-moving hip joints that allow a reciprocal gait pattern.

13
Q

What is a RGO?

A

A Reciprocating Gait Orthosis
An HKAFO that uses a mechanical system that connects the two sides of the brace by an isocentric bar (IRGO), double cable (LSU RGO from Louisiana State Univeristy), or single push/pull cable system (advanced RGO [ARGO])
The patient achieves a reciprocal gait by shifting body weight forward and laterally while extending the hips and upper trunk.

14
Q

What is the HALO in regards to Lower limb SCI?

A

Hip and Ankle Linked Orthosis
It is a cable system that links both ankle joints with a medial hip joint. The linkage of the ankles by way of a pulley system results in assistance of the swinging leg when the contralateral ankle is flexed.

15
Q

What is the SCO?

A

Stance Control Orthosis
Has knee joints that provide stability during stance but free motion during swing. It reduces the energy required during gait.

16
Q

What are the different standers available for children?

A

L-Frame
Parapodium
Swivel standers
The Rabbit: Strapped into a stander with wheelchair like wheels for mobility.

17
Q

You have an athletic patient with a T9 injury and no significant comorbidities. Their goal is spontaneity of activities for short distances. What orthoses could work for them?

A

KAFOs

18
Q

You have a patient with a T9 injury and no significant comorbidities. The patient is interested in using an orthosis for limited function and prefers a reciprocating gait pattern. What orthoses should they use?

A

A Parawalker or RGo to be more stable.

19
Q

What orthopedic considerations might affect the patient if they want to stand?

A
Scoliosis
Pelvic Obliquity
Hip subluxation/dislocation
Lower Limb contractures
Spasticity
History of Lower limb fractures.
20
Q

Which contractures might prevent the patient from standing?

A

30 degrees hip flexion contracture
20 degree knee flexion contracture
15 degrees of plantarflexion contracture

21
Q

What might reduce spastisity or make it worse?

A

Standing reduces spasticity

But movement may trigger a patient’s spasticity

22
Q

Which braces can be used for patients with SCI at motor level L2 or above?

A

HKAFOs (including RGOs) and KAFOs

23
Q

What are the benefits of the HGO?

A

Lateral stiffness, which prevents adduction during swing through of the free limb, and broad footplates, which encourage stability during double limb stance.

24
Q

What patient’s will benefit from an added pelvic section in a HKAFO

A

Patient’s with hip obliquity due to scoliosis or hip subluxation.
Children with pliable Y-ligaments.

25
Q

Transverse stability below the hips can be achieved how?

A

With a spreader bar, but it eliminates the possibility of a reciprocal gait.

26
Q

How can you provide reciprocal gait without transversing the hip?

A

KAFO section linked with a single medial hinge joint such as the walkabout orthosis (WO) or the primewalk orthosis.

27
Q

Patients with SCI are at risk for chronic conditions of age due to inactivity such as what?

A

Hypertension
Cardiovascular disease
Obesity
Diabetes.

28
Q

Why are orthoses prescribed for patients with SCI?

A
Stabilization after injury
Anti-footdrop to prevent contractures
TLSOs for spine and pelvic stability
Therapeutic and functional upright mobility
independence
Decrease energy cost
29
