The Gait Cycle Flashcards
During heel strike, the hip is moving to
extension
What sort of action is occurring at the gluteus maximus and hamstrings during heel strike?
powerful concentric contractions to propel the body forwards
they are acting as agonists
What sort of action is occurring at the illiopsoas during heel strike?
eccentric activity of the iliopsoas which acts as the antagonist
During heel strike, the knee is forced into _________ by the __________ activity of the ______, __________ and ___________ all acting as ___________
extension isometric hamstrings quadriceps femoris gastrocnemius stabilisers
During heel strike, the ankle is
severely dorsiflexed but is moving into plantarflexion
The line of gravity lies _______ to the hip
posterior
The line of gravity lies _______ to the knee
anterior
The line of gravity lies _______ to the ankle
anterior
What sort of action is occurring at the tibialis anterior during heel strike and why?
eccentric activity of the tibialis anterior (acting as the antagonist) in order to control the lowering of the ball of the foot
What sort of action is occurring at the triceps surae during heel strike and why?
concentric activity of the triceps surae (soleus and gastrocnemius) which acts as the agonist, in order to control the lowering of the ball of the foot
During mid-stance, the hip is moving through
extension
What sort of action is occurring at the gluteus maximus and hamstrings during mid-stance?
concentric activity to propel the body forwards
they are acting as agonists
What sort of action is occurring at the illiopsoas during midstance and why?
eccentric activity of the iliopsoas which acts as the antagonist to stop this happening too quickly
During mid-stance, the knee is forced into _________ by the __________ activity of the ______, __________ and ___________ all acting as ___________
extension isometric hamstrings quadriceps femoris gastrocnemius stabilisers
What sort of action is occurring at the triceps surae during mid-stance and why?
concentric activity of the triceps surae (soleus and gastrocnemius) which acts as the agonist, in order to control the lowering of the ball of the foot
During late stance, the hip is in
extension
What sort of action is occurring at the gluteus maximus and hamstrings during late stance?
concentric activity
they are acting as agonists
What sort of action is occurring at the illiopsoas during late stance?
eccentric activity
acting as the antagonist
During late stance, the knee _______ and becomes slightly ______ to prepare for the foot to leave the ground. There is _______ action of the ________ and __________ which act as _________.
unlocks flexed concentric hamstrings gastrocnemius agonists
During late stance, the ankle is severly
plantar flexed
During late stance, what sort of action is occurring at the triceps surae and why?
strong concentric action, acting as the agonist for strong propulsion
During early swing, the heel is in
extension, moving to flexion
What sort of action is occurring at the gluteus maximus and hamstrings during early swing and why?
eccentric activity of the gluteus maximus and hamstrings both acting as antagonists to control the rate of swing
What sort of action is occurring at the illiopsoas during early swing?
concentric activity of the iliopsoas acting as the agonist
During early swing, the knee is swung like a pendulum in _______. There is therefore _______ activity of the _________ and ________ to stop the toes from touching the ground.
flexion
concentric
gastrocnemius
hamstrings
During early swing, the ankle is in
plantar flexion moving into dorsiflexion
What sort of activity is occurring at the tibialis anterior and why?
concentric activity acting as the an agonist to allow clearance of the toes during swing
During mid swing, the hip is in
flexion
What sort of action is occurring at the illiopsoas during mid swing?
concentric activity of the iliopsoas acting as the agonist
What sort of action is occurring at the gluteus maximus and hamstrings during mid swing and why?
eccentric activity of the gluteus maximus and hamstrings both acting as antagonists to control the rate of swing
The knee continues to be swung like a pendulum and here it is in _______ ________. There is _______ activity of the _________, __________ and ____________.
stable flexion isometric gastrocnemius hamstrings quadriceps femoris
During mid swing, the ankle is in
dorsiflexion
During mid swing, what sort of activity is occurring by tibialis anterior and why?
