Normal Gait - English
Terms in this set (34)
what are the stages of motor control
mobility, stability, controlled mobility, skill
which stage of motor control: ability to move extremities and trunk. Initiate and move through ROM for function. Develops first
which stage of motor control: develops as we mature and the trunk develops postural control. Total body patterns lead to stability. Think co-activation
which stage of motor control: stabilize distal component and move proximal pivot. Demands dynamic stability. An example is stance phase where you are moving, but also maintaining stability
which stage of motor control: highest level of movement that involves coordinated motions and requires proximal stability
what are the 6 determinants of gait
1. pelvic rotation
2. pelvic tilt
3. knee flexion
4. foot mechanism coordinated with
5. knee mechanism
6. lateral displacement of pelvis/body
pelvic _______ occurs about 5 degrees in each direction, flattens the arc of the center of mass, and reduces energy cost
pelvic ________ occurs contralateral to the stance leg about 5 degrees. There is relative __________ of the stance hip and relative __________ of the swing hip. This flattens arc of COM and reduces energy cost
tilt; adduction; abduction
the knee ________ in weight acceptance and single limb stance. This flattens the arc of the COM and reduces energy cost. This also allows forces to be absorbed by __________ rather than joints
The foot and knee mechanism:
foot and knee are _________ in weight acceptance at initial contact. COM is _______ at initial contact.
the foot and knee mechanism:
at single limb stance, the ankle ________ with knee _________ and then _________
at weight unloading, the ankle __________ then knee ___________
dorsiflexes; extension; flexion
during gait, COM is lowest at __________ __________ and highest at ___________
double stance; midstance
if feet are further apart, then there is more __________ displacement of the pelvis and you are ________ energy efficient
What is the normal distance between heels during gait
how do impairments affect gait resulting in inefficient gait patterns. Ex: instability of hip, ataxia of LE, LE extensor spasticity
take away one or more of 6 determinants
active torques are generated by ____________ and they counteract passive torques which are generated by ____________
at initial contact, the line of gravity goes ___________ the knee resulting in a passive torque for knee ____________ which is counteracted by active torque from what muscle?
behind; flexion; quads
at initial contact/heel strike the subtalar joint is _________ moving to __________. The ankle is _________ moving to ___________. The knee is near ___________ moving to __________
supinated; pronation; neutral; PF; extension; flexion
at initial contact/heel strike the hip is slightly __________ and __________ __________ moving toward ____________ ___________. The pelvis is __________ and rotating __________ the line of progression
flexed; externally rotated; internal rotation; level; toward
at loading response/foot flat the subtalar joint is __________ moving toward more __________. The ankle ___________ to max in weight bearing. The knee __________ slightly, then moves toward _____________
pronated; pronation; plantarflexes; flexes; extension
at loading response/foot flat the hip _________ and reaches near max ___________ __________. The pelvis experiences lateral drop to __________ side and reaches max ___________. The trunk is rotating _________ to the pelvis.
flexes; internal rotation; swing; rotation; opposite
at loading response, what stages of motor control are to be considered the most?
stabilization and controlled mobility
at midstance the subtalar joint is in max __________ then moves toward ____________. The ankle is ________ moving toward ___________. The knee is slightly ___________ moving toward _____________.
pronation; supination; neutral; dorsiflexion; flexed; extension
at midstance the hip is __________ to neutral and moves into more ___________ ____________. The pelvis drops toward the _________ side. The trunk has maximal ___________ displacement and is aligned over the _________ leg.
extending; external rotation; swing; lateral; stance
at terminal stance/heel off the subtalar joint is ___________. The ankle is ____________ maximally, changing to ____________. The knee is near ____________ and then initiates _____________.
supinating; dorsiflexed; plantarflexion; extension; flexion
at terminal stance/heel off the hip ____________ maximally and is in _____________ ___________. The pelvis is _________ with max rotation _________ from the line of progression.
hyperextends; external rotation; level; away
in preswing/toe off the subtalar joint is in max ___________. The ankle is in max __________. The knee is ___________ toward max.
supination; plantarflexion; flexing
in preswing/toe off the hip is in max _____________, reaches max __________ __________, then begins _____________. The pelvis begins to drop __________
hyperextension; external rotation; flexion; laterally
in initial swing/acceleration the subtalar joint is moving toward _________ from ___________. The ankle is ___________ moving toward neutral. The knee is _________ to max.
neutral; supination; plantarflexed; flexed
in initial swing/acceleration the hip __________ toward max and is ____________ ___________ but moving toward IR. The pelvis is dropped to the __________ side
flexes; externally rotated; swing
in midswing the subtalar joint is ____________ moving to neutral. The ankle is ____________. The knee is __________ but moving to ______________
supinated; neutral; flexed; extension
in midswing the hip is __________ to max and is __________ ____________. The pelvis is dropped to max on the ___________ side
