Flashcards in Spinal cord injury CC4 Deck (51):
1

acute consequences of sci

weakness with a neck injury leads to 

quadriparesis/plegia

2

acute consequences of sci

weakness with a caudal injury leads to 

paraparesis/plegia

3

htn or hypotension in acute phase of sci?

hypotension

4

urinary ___ in acute phase of sci

retention

5

Acute consequences of SCI? (5) 

 quadriparesis/plegia (neck) paraparesis/plegia (caudal)

Sensory loss or abnormalities

Hypotension

Urinary retention


Orthopedic pain 

6

chornic consequencies of sci? (10

1. involutnary mvoements

2. bladder problems

3. decreased bowel motiblity

4. sexual dysfunction

5. increased risk fo blood clots

6. pressure ulcers

7. autonomic dysfunction

8. metabolic disorders 

9. musculoskeltal breakdown/fracures

10. psych

7

above T10 injury , bladder problems are 

spastic/neurogenic bladder (most common).

 

Can’t voluntarily relax the external urethral sphincter, so it stays tight as bladder fills.

8

below T12, bladder sx are 

 flaccid bladder, can’t contract for emptying

9

management of flaccid bladder 

manage using...intermittent catheterization, condom catheter, indwelling/Foley
catheter, or suprapubic catheter 

10

male sexual dysfunction? 

Male, sperm viability is impaired / fertility is impaired. 

11

female sexua problems? 

Female, fertility is mostly unaffected but C-section delivery strongly recommended (b/c of autonomic dysreflexia)

12

Pressure ulcers from __

cutaneous ischemia

13

Autonomic Dysfunction: sympathetic damage = impaired ___

thermoregulation

14

* Autonomic Dysreflexia with SCI =

 extreme blood pressure swings (240/160) + low heart rate

15

what causes autonomic dysreflexia? 

occurs in response to strong afferent input, ex. pain or overly full bladder

16

what can happen with repeated occurenced of autonomic dysrefelxia? 

chronic hypertension

17

metabolic disorders with spi are often due to

lifestyle difficuluties

18


___ sp injuries/year

10,000-12,000

19

> 50% of injuries are to ___ spine

cervical

20

> 50% are neurologically “incomplete” - means there is sensation

in S4-S5 region.

21

“complete” means bilateral injury with total loss of 

sensation below injury level

22

ASIA scale: A is ___ injury

complete/worst injury

23

ASIA sale B-D is ___

incomplete

24

ASIA scale e is __

 is normal

25

Three approaches to SCI treatment:

 

1. Neuroprotection of surviving cells/axons from toxic injury environment

2. Neurorestoration via replacement cells, neurotrophins, and establishing a growth-
permissive environment


3. Neurorehabilitation by strengthening existing systems and retraining circuits

26

 methylpredinisolone (steroids) trials results

1. found higher mortality in higher tx group

2. another found asia scale improvement in pts who were incomplete, 24 hr dosing

3.  48 hr dosing beter

27

parapesis/plegia occurs caudal to __

t1

28

for___that are crushed by the intial truamtic injury nothing can be done those are gone for food 

 nerve cell bodies 

29

among pts who started tx ___ of injury the 48 MP group receovered signfiicantly more funciton at 6 weeksn and 6 months than those with 24 MP

3-8

 

30

Spontaneous ____ movements seen in patient with C5 incomplete SCI for 17 years

stepping

31

Spontaneous stepping movements seen in patient with C5 incomplete SCI for 17 years 

 Caused by arthritic degeneration and subluxation in R. hip ---> ___ triggeered  CPG

pain upon hip extension

32

Characteristics of all these walking CPG manifestations:

 

 Always associated with___nput to the spinal cord

 pathology / noxious i

33

 Can be “trained” to improve ___ walking in persons with incomplete SCI

voluntary

34

Studies on Walk-Training with Body-Weight Support
Most subjects show some improvement, but 

no greater than seen with physical therapy

35

Studies on Walk-Training with Body-Weight Support

is wlaking cpg being trained?

no evidence 

36

Studies on Walk-Training with Body-Weight Support

where were impovements seen? 

 better balance, stronger leg muscles, improved fitness

37

Autonomic Dysreflexia  Typically seen after ___ or ___ SCI

cervical or high-thoracic

38

Autonomic Dysreflexia is more common after ___ sci

compelte

39

Potential causes of autonomic dysreflexia? (4)

1. loss of brain/brainstem inhibition to symps

2. excessive sensory
response to stimuli

3. excessive sympathetic response to normal sensory input


4. excessive vascular response to normal sympathetic activity

40

in all cases of cpg walking 

all were rhythmic but not reciprocal

between agonists and anatogists

41

electrical stim to ___ can give rise to leg emg comparable to cpg results

lumbar enlargement

42

what si the cpg in human characterized by?

A image thumb
43

interlimb reflexes are observed in all persons with

chronic cervical sci

44

interlimb reflex is more common in 

distal upper limb muscles

45

is interlibm reflex found in able bodied subjects?

no

46

early interlimb reflexes from

conenctions already established (latents syanspes)

47

late interlimb reflexes are from ___ connections

novel (regenerative sproutin)

48

do interlimb reflexes disappear?

no

49

what happens to interlimb reflexes once they appear

A image thumb
50

interlimb reflexes are liekly due to new growth within the spinal cord ___

caudal to the lesion

51

interlimb reflexes are possibly the basis for

autonomic dysreflexia
