STS Flashcards
What are the three impairments related to the flexion momentum phase?
- inability to get feet back
- inability to generate trunk momentum
- reliance on arms
Poor timing of TA
RAS
FES
EMG
Reduced TA force
decrease friction
target
FES
stool walking
Reduced gastroc flexibility
stretching
whole practice with active stretch
Reduced ankle proprioception in sitting
approximation
theraband on chair
visual or joint feedback
mental imagery
Gastroc spasticity
EMG
What sequence is lost when patients do not quickly flex trunk to 60 degrees?
extension of knee, hip, ankle
Fear of falling
PT position
part practice
mental image
Impaired force of RF and paraspinals
trunk target training (add resistance, scapula and clavicle)
C-curve tracing
Impaired fractionation
RAS
target training
forced use (lower seat height)
What are the two impairments related to the momentum transfer phase?
- insufficient flexion of hip, knee, ankle
2. asymmetry in loading
Number of degrees needed in momentum transfer?
knee 90
hip 90
ankle 23
Reduced limb loading
mental practice
forward reach
destabilize stronger LE
place strong foot forward
Reduced orientation to longitudinal axis
visual feedback
What are the two impairments in the extension phase?
- insufficient extension of trunk, hip, knee, and ankle
2. asymmetry in EXT
Reduced power of glute max, quad, and calf
part practice lower seat height add resistance STS whole practice Stand to sit (eccentrics) EMG
Problems with STS occur if greater than __ % difference in leg vertical force
30%
Why do individuals post stroke not perceive a difference in WT bearing during STS?
perception of motor recruitment effort in quad (trying to achieve the same exertion feeling as before the stroke)
Poor orientation to longitudinal axis
visual feedback
Reduced limb loading (proprioception and sensation)
proprio- imagery, visual feedback, PNF, approximation
cutaneous sensation- discrimination, FES
Ankle PROM and admission FIM cognition scores are predictors of what?
STS outcomes and discharge home
What is the one impairment in the stabilization phase?
excessive sway
Reduced ankle proprioception in standing
Target practice with Ant. to Post. tibia movement in standing
approximation
push with toes in Ant. sway, lift toes with Post. sway
mental imagery
impaired TA activation in standing
FES to TA while swaying post
EMG to AP sways
push lift with toes with post. sway
tapping muscle
Reduced gastroc flexibility in standing
stretch
emphasize active ankle DF with heel on ground
mini squats with foot flat
Impaired timing of TA and gastroc in standing
EMG
Wall push offs
RAS (clap)
