Gait Flashcards
manner in which a person walks,
ability to move from one place to another
gait
locomotion
gait cycle?
IC loading response mid stance terminal stance pre-swing/ toe off
60/40
kinetic vs kinematic
describe forces
describe movement
Spatial measures of gait>?
temporal?
step/stride length/ width/ foot angle
cadence/velocity/stride time
Prerequisites for functional gait?
stance stability
clearance in swing
swing pre-positioning
step length
IC norms
ankle:neutral-PF
knee: neutral–ext
Thigh:20 deg.-flex
pelvis: 5 deg forward rotation
LR norms
ankle: neutral ecc PF torque
knee: flexion torque quad ecc
hip: 20 flex/ add torque
Pelvis: remains rotated foraward
mid stance norms
A: 5 deg DF torque
K: Neutral w/ quad quiet gastric ^ /ext torque
H: extend torque to neutral
P: neural
TS norms
A:DF & MTP Ext. DF torque greatest muscle demand at DF nd calf
K:neutral ext torque
H: 20 deg ext tq
P: rotates backward
Pre-swing norms
A: 15 deg/ MTP 60 deg
K: 40 deg
H: Extended
P: 5 deg backward
Stance phase rocker positions
heel
ankle
forefoot
toe?
LR
MS
TS
PS
Initial swing norm
A:5 deg PF: tips initial DF
K: 60 deg flexion(tq) (from hip and tib)
H:15 deg flexion
P:5 deg rotation
Mid swing norm
A:Neutral
K: 25 deg ext torque
H: 25 deg flex torque
P: neutral
TS norm
A: pretrials active
K: neutral (hammy decelerate)
H: prep for weight acceptance
P:rotate forward.
What is stabilizing in all planes during gait?
back extensors+abs
RA in MS and TS
Erectors in Preswing
What are the functional tasks?
Weight acceptance
Single limb support
swing limb advance
A visible forward then backward movement of thigh during terminal swing?
Past retract. just slapping it back..
decreases step length.
What are some trunk deviations?
leans (lat/f/b)
rotation (cant dissociate)
help reduce load on other structures
what are the pathological gait pattern?
ataxic (stagger wide BOS -cerrebellar)
Festinating (on toes PD)
Scissor (cross midline CP/CVA/TBI)
What is included in neuroplasticity in locomotor training?
specificity amount (most important) intensity (increase it)
Principles of locomotor training?
Maximize LE loading
Enhance sensory cues (fácil)
optimize kinetics (posture/coordinate)
Training of one motor task may affect performance of biomechanically separate tasks
Leapfrog effect
via overlapping neural circuits
activities of pregait?
parallel bars
weight shift
f/b steps
stability before mobility
Bracing/orthotic interventions?
control DOF and improve mechanics
or use stimulation
