Q

With ASIA C motor function is _ below the neurological level and _ than 1/2 of the key muscles below the neurological level have a muscle grade of _ than _/5.

A

With ASIA C motor function is PRESERVED below the neurological level and MORE than half of the key muscle below the neurological level have a muscle grade of LESS THAN 3/5

17
Q

With ASIA D, motor function is _ below the neurological level and _ _ _ of key muscles below the neurological level have a muscle grade of _/5 _ _.

A

Motor function is PRESERVED below the neurological level and AT LEAST HALF of key muscles below the neurological level have a muscle grade of 3/5 OR GREATER

18
Q

ASIA E, motor and sensory function are? Valid for?

A

. . . Are NORMAL

Valid only for people who have had a a spinal cord injury

19
Q

The neurological level is the most caudal level that exhibits? Exceptions? Associated levels?

A

Most caudal level that exhibits intact sensory AND motor function

SCI’s that are in levels that are not testable using MMT are considered to be the same as the sensory level

Levels that cannot be tested by MMT include: C1-C4; T2-L1; S2-S5

20
Q

_ of _ _ is sensory and/ or motor function below the neurological level excluding S4-S5. Dermatomes and/ or myotomes below the neurological level remain? Only applies to?

A

ZONES OF PARTIAL PRESERVATION is sensory and motor . . .

Dermatomes and/ or myotomes below the neurological level remain PARTIALLY INNERVATED

Only applies to ASIA A (COMPLETE SCI)

21
Q

With _ _ syndrome there is flaccid paralysis of the lower extremities and areflexic bowel and bladder.

A

With CONUS MEDULLARIS syndrome there is . . .

22
Q

Most spinal cord injuries are a combination of? _ T12 is more _ () and _ T12 is more _ ().

A

Most spinal cord injuries are a combination OF UMN AND LMN

ABOVE T12 is more UMN (SPASTICITY)

BELOW T12 is more LMN (FLACCIDITY)

23
Q

What are the first and second line (2)of pharmacological agents used to treat spasticity in SCI?

A

First- BACLOFEN

Second- GABAPENTIN (also good for cerebral spasticity- in addition to spinal) and BENZIDIAZAPINE (diazepam/ Valium)

24
Q

_ _ occurs with SCI above the T1 level.

A

THERMOREGULATION DSYFUNCTION

25
Q

_ _ is ectopic bone formation in the connective tissue outside of the skeleton. Occurs at the _ joints (_, _, _), always occurs _ _ _ of the spinal lesion. May occur in / of high tetraplegics and those with accompanying TBI.

A

HETEROTOPIC OSSIFICTION is ectopic bone . . .

Occurs at the LARGE joints (HIP, KNEES, ELBOWS), always occurs BELOW THE LEVEL of the spinal lesion.

May occur in SHOULDERS/ ELBOWS of high tetraplegic . . .

26
Q

HO occurs in _% of people with SCI. Most commonly develops - _ post injury with peak incident around _ _. However it can occur _ after injury.

A

HO occurs in 50% of people with SCI

Most commonly develops 1-4 MONTHS post injury with peak incidence around 2 MONTHS

However it can occur YEARS after injury

27
Q

How many stages of HO are there? How is it diagnosed by imaging? Lab?

A

4 STAGES

It is diagnosed via BONE SCAN (most accurate test)

Lab results: ELEVATED PHOSPHATASE LEVELS

28
Q

Stage _ occurs 11-20 days after injury. Symptoms include: _, _ _ swelling, _, local _ and _ near the joint. _ _ _on X-Ray. ROM may be _ _.

A

Stage I occurs 11-20 days after . .

Symptoms include: FEVER, SOFT TISSUE swelling, local WARMTH and REDNESS near the joint

NO DETECTABLE CHANGE on X-Ray

ROM may be SLIGHTLY LIMITED

29
Q

Stage 2: symptoms are? X-Ray- _ _ is now visible. ROM?

A

Symptoms ARE SAME AS STAGE 1

X-Ray- ECTOPIC BONE is not visible

ROM: MAY BE SLIGHTLY LIMITED (same as stage 1)

30
Q

Stage 3: symptoms- __ and _ subside. X-Ray shows _ _. ROM is _ limited.

A

Symptoms- SWELLING AND REDNESS subside

X-Ray shows CONTINUED CALCIFICATION

ROM is INCREASINGLY limited

31
Q

Stage 4: _- _ _ after onset. X-Ray shows _ _. ROM- _ _. Complications include? (2)

A

2-4 WEEKS after onset

X-rays show EXTENSIVE CALCIFICATION

ROM- JOINT ANKYLOSIS

COmplications include- CONTRACTURE AND PRESSURE SORES

32

ADA COMPLIANCE: handrail/ grab bar height? Toilet seat? Counter height?

A

Handrail/ grab bar height: 34-38 inches

Toilet seat height: 17-19 inches

33
Q

ADA Ramp requirements: width? Slope should not exceed _ _ in height for ever _ _ in length. Ramps greater than 6 feet should have?

A

Width: 36 inches

Slope should not exceed 1 INCH in height for every 12 INCHES in length
