CVA Impairments 4: Gait/Assistance/Orthotics Flashcards
0-0.4 m/s gait speed is associated with
household ambulation
(0-0.2 = d/c to SNF)
0.4-0.8 m/s gait speed is associated with
limited community ambulator
0.8 - 1/2 m/s gait speed is associated with
community ambulation
1.2 - 1.4 m/s gait speed is associated with
crossing street, normal walking speed
Preferred gait speed of chronic stroke patients is
0.10 m/s to 0.76 m/s
_______ weakness could result in compensation at the trunk seen as an ipsilateral trunk lean
glute med
Pelvis/Hip at IC - MSt
↓ pelvic rotation/hip flexion
↑ hip IR/ adduction (Trendelenburg)
3 Common Knee Patterns IC –> MSt
- ↑ flexion (IC)
- ↓ flexion early stance > hyperext mid-late stance
- Excessive hyperext throughout most of stance phase
Common foot/ankle patterns IC –> Mst
↓ TIBIAL PROGRESSION
↓ ankle DF
Lack of heel strike
Flat foot contact
Instability at foot ankle contact > inversion, supination
Pes Planus
Pelvis/Hip at MSt > TSt
↓ pelvic rotation
↓ hip EXT/TSt
Hip flex (forward progression)
Knee at MSt > TSt
↓ knee EXT
Knee buckling
Delayed movement into knee flex (prep for swing)
Foot/ankle at MSt > TSt
↓ tibial progression (step-to)
↓ heel off at terminal stance
Pelvis/Hip in swing
↓ hip flex
hip hiking
circumduction
↑ compensatory ER
Knee in swing
↓ knee flex
Foot/ankle is swing
↓ DF (poor foot clearance, toe drag)
↑ inversion
You note your patient is tripping over obstacles on the floor and appears to have a decreased awareness of obstacles during ambulation. You hypothesize this could be due to?
visual deficits (dysconjugate gaze!!)
Your patient has significant veering and ambulates in a curved path. You have ruled out visual impairments, what do you suspect is wrong?
visuospatial inattention
T/F Foot orthoses are beneficial to stabilize the foot thereby giving ankle stability.
False (NO ankle support)
Foot orthoses
orthotics used to redistribute forces on the foot (transfer WB stresses to pressure-tolerant sites, correct alignment, protect painful areas from contact, etc.)
3 Most common indications for AFO:
Weakness, impaired proprioception, spasticity
Describe what observations in swing and stance would warrant an AFO
Swing: poor foot clearance, foot drop
Stance: ankle instability, knee buckling, hyperextension
Contraindications for any LE Orthoses
- Ankle clonus
- LE swelling
- Significant or poor healing/skin breakdown
Precautions for any LE orthoses
- Decreased ROM in joints to be braces
- Sensory Impairments
- Cognition, communication +/- perceptual deficits
List the AFO from most supportive to least supportive
Stirrup/Double upright
Solid
Pre-hinged
Hinged/articulated
Ground reaction
Posterior Leaf spring
Your patient has CHF with bilateral LE edema that varies throughout the day. They have had a stroke leaving them with R foot drop. What AFO would be appropriate for this patient? What do you need to consider when choosing this type of AFO?
STIRRUP/DOUBLE UPRIGHT AFO
-Permanently attached to shoe
-HEAVY
-Can be unlocked to allow DF
