Gait and rotational profile Flashcards
Asking a pt to speed up during gait analysis will __________ gait deviations
increase
What are the 5 attributes of ambulation
Stability in stance
foot clearance in swing
prepositioning of the foot for initial contact
adequate step length
energy conservation
When does the first rocker come into play?
Initial contact/ loading response
When does the second rocker come into play?
Midstance
When does the 3rd rocker happen?
heel rise/ terminal stance
When does the 4th rocker happen?
Preswing
Excessive hip flexion is a gait deviation in what plane?
Sagittal
Excessive adduction (scissoring) is a gait deviation in what plane?
Coronal/frontal
Malrotation of the hip is a gait deviation in what plane?
Transverse
In CP, the hip ____, __________and _____ are overactive compared to their antagonists
Flexors, internal rotators, and adductors
What is compensated Trendelenburg gait?
Lean toward opposite side of pelvis drop
What is a potential cause of circumduction gait
inadequate hip flexor or knee flexor, excessive hip IR, or ankle plantarflexion
spasticity in adductors causes what kind of gait
scissoring
Stance phase errors are associated with _____
Swing phase errors are associated with _____
abnormal position or malrotation
Inadequate ROM or weakness
Excessive knee flexion causes increased demand on __________ and leads to increased energy expendature
Quads and HIp extensors
Excess knee flexion drives the ground reaction force __________-
posteriorly
What is the most common swing phase deviation?
Decreased knee flexion, stiff leg gait pattern
Why do children with CP often have a stiff leg gait pattern
Use of rectus femoris to augment hip flexion
Because rectus femoris is busy working at the hip it is stiff at the knee
The most common stance error at the ankle caused by excessive plantarflexion is _____
an excessive plantarflexion/knee ext couple
when plantarflexors fire it helps pull the knee into ext
If a pt has excessive knee ext/plantarflexion couple, the ________ rocker is absent
First rocker
What happens during an excessive knee ext/plantarflexion couple
Gastroc stretches prematurely at both ends of muscle, it contracts prematurely causing hyperext in midstance d/t plantarflexor tightness
a crouched gait is often due to a weak ________
soleus
In hemiplegic CP, you often see what foot position
What about Diplegic CP?
Hemi: Overactivity of the post tib/gastroc causes equinovarus/calcaneal inversion
Di: Overactiviy of peroneus brevis and gastroc causes equinovalgus (calcaneal eversion)
When would you want to do a rotational profile on a child
if they have excessive intoeing or outtoeing
