PT Mgmt of Pts w/ SCI Flashcards
SCI Stats
~13000 new SCI/year
~300,000 persons living w/ SCI
NOTE: LOS 1970s vs. now→ relevant due to their goals and time we get to spend w/ them!!!
STATS

STATS
- Life expectancy
- Mortality rates highest in 1st yr after injury
- Cause of death generally from pneumonia or septicemia
Classification of SCI
*components
- Lvl on injury
- Complete vs. Incomplete injury
- ASIA/AIS Scale
- A→ Complete
- E→ Normal
ASIA/AIS ISNCSCI Form
see pics
*also on Canvas
ASIA Scale
*Sensory Testing
- Based on 28 dermatomes
- Lt touch AND sharp/dull
-
Grading
- 2= intact
- 1= impaired
- 0=absent
ASIA Scale
Sensory Testing
Grading Scale described
-
2= Intact
- report touch & describe it feels same as face
- face bc want to compare to somewhere neutral
- report touch & describe it feels same as face
-
1= Impaired
- report touch but does NOT feel same as face
-
0= Absent
- Not correctly/reliably reporting being touched
ASIA Scale
Motor Testing
- Confounded by mult. lvl innervation of mm’s
- Muscle tests may reflect function of 2 or more cord segments
- Muscle tests are NOT standard MMTs that PTs reg. perform
- pt is supine
- Looking @ is mm neurologically intact?
- To determine level of innervation→ tester looks for strength of 3/5 in one muscle and at least 4/5 in the next most rostral (sup.) muscle
ASIA Scale Motor Testing
Muscle Grades described..
- 0= NO mm contraction
- 1= Any visible or palpable contraction
- 2= Able to move @ least 1x thru full ROM in gravity eliminated pos.
- 3= Full ROM against gravity
- 4= Full ROM w/ some resistance
- 5= Full ROM w/ full resistance
ASIA Scale:
Key Muscles
- C5→ Elbow FLEX
- C6→ Wrist EXT
- C7→ Elbow EXT
- C8→ DIP flex of middle digit (hand intrinsics)
- T1→ 5th digit ABD
- L2→ Hip FLEX
- L3→ Knee EXT
- L4→ Ankle DF
- L5→ Long toe EXT
- S1→ Ankle PF
ASIA Scale
*Key Muscles
Describe the Anal-Rectal Muscle Test
- Looks @ deep anal pressure/contraction
- Anal-Rectal Muscle Test
- finger in rectum
- sensation? contraction?
- *Helps det. classification of exam and SCI
- finger in rectum
Severity of SCI Injury Classification
*NOTE about Deep anal pressure
For injury to be INCOMPLETE→ Pt HAS to be able to detect deep anal pressure
*NO anal contraction, but do have deep anal PRESSURE
Severity of Injury Classification
ASIA A = COMPLETE
COMPLETE
- NO motor OR sensory function is preserved in the sacral segments S4-S5
- aka NO anal-rectal function (No sacral sparing***)
Severity of Injury Class.
ASIA B= INCOMPLETE
INCOMPLETE
-
Sensory, BUT NOT Motor function is preserved BELOW the neuro lvl and includes the sacral segments S4-S5
- they can detect deep anal pressure, BUT NO ANAL CONTRACTION
Severity of Injury Class.
ASIA C= INCOMPLETE
INCOMPLETE
- Motor function IS PRESERVED below neuro lvl, and More than HALF of key muscles BELOW neuro lvl have a mm grade LESS THAN 3
Severity of Injury Class.
ASIA D= INCOMPLETE
INCOMPLETE
- Motor function IS preserved BELOW neuro lvl, and at least HALF of key muscles BELOW neuro lvl have a muscle grade of 3 OR MORE
Severity of Injury Class.
ASIA E= NORMAL
NORMAL
- Motor AND Sensory function are Normal
Clinical SCI Syndromes
Anterior Cord Syndrome
Facts:
- Most common incomplete syndrome
- Usually due to:
- head on collision
- Blow to back of head
- Common assoc’d fx:
- Ant. Wedge Fx
- Fx of Post. elements
- SP, laminae and pedicles
Clinical SCI Syndromes
Anterior Cord Syndrome
*Presentation
- Loss of motor function
- Dmg to corticospinal tract
- Loss of pain and temp sensation
- Dmg to spinothalamic tract
-
Proprio and Kinesthesia INTACT**
- DCML spared
Clinical SCI Syndromes
Central Cord Syndrome
*FACTS
- Common w/ C/S hyperextension
- Assoc’d w/ a narrowed vert. canal
- older adults→ stenosis
- Freq caused by:
- rear end MVA
- Fall in which chin strikes stationary obj
- *Results in:
- edema and/or bleeding INTO central grey matter of SC
Clinical SCI Syndromes
Central Cord Syndrome
*Presentation
think “sacral sparing”
- Injury most often in the cervical region
- Loss of UE function w/ relative sparing of LEs
- Pts often ambulatory
- INC risk of falls and injury from falls 2* to absent UE protective EXT
- diff. utilizing ADs
- AKA “Walking Quad”
- zero arm function BUT can ambulate
Clinical SCI Syndromes
Hemi-cord (Brown-Sequard) Syndrome
*“Hemi”→ think “HALF”
FACTS
- Often caused by a penetrating wound to cord
- Prognosis is generally good for regaining ambulation, hand and B&B function
Clinical SCI Syndromes
Hemi-Cord (Brown-Sequard) Syndrome
*Presentation
-
IPSILATERAL LOSS of motor function and pos. sense BELOW LVL OF LESION
- Dmg to corticospinal tract and DCML
- Ipsilateral bc look @ where tract crosses
- Dmg to corticospinal tract and DCML
-
CONTRALATERAL LOSS of pain and temperature sensation beginning a few lvls below lesion
- Dmg to spinothalamic tract, which ASCENDS IPSILAT. for a few segments before crossing
- this is why its a few lvls down
- Dmg to spinothalamic tract, which ASCENDS IPSILAT. for a few segments before crossing
Clinical SCI Syndromes
Posterior Cord Syndrome
FACTS
- LESS COMMON THAN OTHERS
- Usually caused by compromise of Post. Spinal Artery
- Often a long-term consequence of Tabes Dorsalis
- *untreated Syphilis
Clinical SCI Syndromes
Posterior Cord Syndrome
*Presentation
- Dmg primarily to DCML (Dorsal Columns)
- Loss of Somatosensation BELOW the lvl of injury→ Cannot feel position of LEGS
- Wide based gait
- Distal signs of Ataxia
Clinical SCI Syndromes
Cauda Equina Syndrome
*FACTS/Presentation
- Below lvl of L1
- NOT a CNS injury
- Results in LMN Syndrome
- Complete lesion is rare bc of # of nerve roots and the area they encompass
- Bc it is a peripheral nerve injury→ SOME possibility for regeneration
Review Tracts:
Corticospinal Tract
Motor
Descending
*crosses @ decussation of Pyramids
Review Tracts: Dorsal Column (DCML)
Sensory
Ascending
*Crosses @ Brainstem
Review Tracts:
Spinothalamic (Anterolateral) Tract
Sensory
Ascending
*Crosses in SC @ Ant Commissure AFTER ascending 1-2 lvls THEN to Thalamus
SCI Stats
more than ⅓ people w/ SCI are re-hospitalized w/in 1st year after injury
SCI Stats
Most common reasons for re-hospitalized
- Genitourinary
- UTI
- Respiratory
- lungs
- Integumentary
- Wounds
SCI Stats
those rehospitalized are more likely….
Younger
female
unemployed/retired
covered by medicaid
Discharged to SNF after first hospitalization***
SCI Stats
Longer rehab stays….
Longer rehab stays are assoc’d w/ DECd likelihood of rehospitalization
Complications of SCI
Several
Living w/ SCI
Autonomic Dysreflexia
MEDICAL EMERGENCY!!!
- Typ occurs in injuries ABOVE T6→ Above splanchnic outflow
Autonomic Dysreflexia
MEDICAL EMERGENCY!!!
What to do…
- Find noxious stimuli
- sit pt upright
- loosen tight clothing
- Monitor HR and BP
- Ask about triggers
- bladder distention
- bowel impaction
- restricting items (catheter, abd binder, etc.)
- seek med. help if sx’s do not resolve quickly
Living w/ SCI
CV Dis Mgmt
- CV issues are leading cause of death following SCI****
- Incd risk of CV disease (2.72 OR) and stroke (3.72 OR) following SCI
- Changes to the ANS after SCI can INC risk of CV sequelae
- abnorm BP
- HR variability
- arrythmias
- altered CV response to exercise
