NBCOT REVIEW Ch 5: Spinal Cord Injury
Terms in this set (33)
What is the ASIA Impairment Scale?
A scale that grades the degree of impairment and severity of injury of a patient.
What is ASIA A?
Complete SCI, no sensory or motor function preserved in the sacral segments S4-S5.
What is ASIA B?
Incomplete SCI, sensory but no motor function preserved below the neurological level, and extends through the sacral segments.
What is ASIA C?
Incomplete SCI, motor function is preserved below the neurological level, and the majority of key muscle groups below the neurological level have a muscle grade level less than 3/5.
What is ASIA D?
Incomplete SCI, motor function preserved below the neurological level, and the majority of key muscle groups below the neurological level have a muscle grade greater than or equal to 3/5.
What is ASIA E?
Normal, no SCI. Sensory and motor function are normal.
Precautions in SCI.
1. Respiratory complications (weak cough and shallow breathing). Do not overdo therapy b/c person does not have control of stomach muscles
2. Skin breakdown: redness, Decubitus ulcers
3. Orthostatic Hypotension: excessive fall in BP when assuming upright position, light-headedness, dizziness, sudden weakness (usually occurs at T6 and above)
4. DVT: swelling in legs, localized redness, low-grade fever. Compression stockings to tx.
5. Autonomic Dysreflexia: exaggerated response of ANS, body's way of telling something is wrong below level of injury: resulting in extreme rise in BP, pounding headache, profuse sweating. Check for obstructions and drain bladder. A medical emergency if not reversed quickly.
6. Genitourinary problems: UTI - cloudy urine, excessive particles, fever, chills, increase in spasticity
7. Heterotopic ossofication: formation of bone in abnormal anatomical locations. Sym: pain, swelling, decrease in A/PROM.
List the types of SCI disease.
Central cord syndrome
Anterior cord syndrome
Conus medullaris syndrome
Cauda equina syndrome
Central Cord Syndrome (Syringomyelia)
- Incomplete SCI
- Commonly occurs in elderly with narrowing/stenotic changes in the spinal canal (of the neck) related to arthritis and
hyper extension of the neck
Bilateral loss of pain & temperature
Flaccidity of the UE (affects UE more than LE)
Hemi-section of the cord
- ipsilateral (same side) spastic paralysis and loss of position sense
- contralateral (opposite side) loss of pain and thermal sense
Anterior Cord Syndrome.
- caused by flexion injuries
- occurs when 2/3 of the anterior cord is lost
motor function, pain, and temperature sensation lost bilaterally below the lesion
below the lesion)
Conus Medullaris Syndrome.
- of the sacral cord and lumbar nerve roots
LE motor and sensory loss
(ability to void only possible by reflex)
Cauda Equina Syndrome.
- LMN lesion
NO spinal reflex activity
Upper Motor Neuron Lesion
- Includes all SCI injuries and diseases that affect the cord between the levels of C1 - T12.
Signs of UMN Lesion.
Below the lesion level:
At the lesion level:
Lower Motor Neuron Lesion
- Carries motor information to skeletal muscles.
- Lesions at the L1 vertebra and lower are LMN injuries.
- All lesions to peripheral nerves are also considered LMN injuries.
Signs of LMN Lesion.
- Within a few weeks of LMN injury, muscles begin to atrophy.
Group the levels of SCI as they are grouped according to functional ability.
Preserved: Head and neck sensation, some neck control
ADL: Dependent in all
Preserved: Good head and neck sensation, neck flexion/extension, rotation, scapular elevation;
ADL: Max assist in all
Preserved: Full head and neck control and sensation,
some shoulder strength
, shoulder ER, Abd to 90 degrees, elbow flexion and supination
ADL: self-feeding with AE (*long opponens splint*), limited self-care with AE (brushing teeth, grooming -
long opponens splint
long opponens splint
AE (*long opponens splint*), limited self-care with AE (brushing teeth, grooming - *long opponens splint*)
Preserved: Fully innervated shoulder movement,
, wrist extension, tenodesis
ADL: self-feeding with AE (
), UE/LE dressing with AE, requires greater assist with LE dressing, self-care with AE
Preserved: elbow extension, wrist flexion,
ADL: Independent in self-feeding, dressing, grooming with AE,
Independent bed mobility and transfers
, meal prep with AE,
driving with hand controls
All UE muscles, FMC present, full grasp
ADL: Independent in all self-care, grooming, and meal prep with AE, driving with hand controls
top half of intercostal muscles
allowing increased respiratory reserve,
long muscles of back
for improved trunk control
ADL: standing possible with assist but not practical for dynamic ADL,
all intercostal muscles and lower abdominals
, providing improved trunk control and endurance
ADL: limited ambulation possible with LE orthotics and AD.
Preserved: hip flexion, adduction, knee extension
Functional ambulation possible
with Bilateral LE orthotics and AD, w/c for energy conservation
Preserved: knee extension present but weak, ankle dorsiflexion
ADL: functional ambulation possible with Bilateral LE orthotics, w/c for energy conservation
Sexual function in SCI
- Mediated by S2-S4 segments of SC.
In T12/L1 or higher SCI
- Pt still has sexual arousal due to touch but not mental stimulation
In L2-S1 SCI
- Pt has sexual arousal from touch (cannot feel erection/lubrication) and mental stimulation
Disorders of Bladder Function in SCI
- Spastic bladder: no voluntary control of voiding but can still have involuntary voiding reflexes, which can cause incontinence and inability to completely empty the bladder
- Flaccid bladder: cannot void voluntarily or involuntarily, urine leakage occurs
Disorders of Bowel Function in SCI
SCI above S2-S4:
- Pt has
spastic defecation reflex
- loses voluntary control of the external anal sphincter but can still defecate with involuntary stimulation
SCI at the S2-S4 level
- Pt has
flaccid defecation reflex
(peristaltic movements cannot evacuate the stool)
- loses anal sphincter tone
UMN Lesions are associated with what type of muscle tone?
LMN Lesions are associated with what type of muscle tone?
