Complex movement Flashcards
Where does our line of gravity sit relative to our knee joint + what is the purpose of this?
anterior- pushes joint into extension and ligaments are tight so joint is locked
What is the Knee doing during early stance?
In extension (locked for stability) - isometric action of quadriceps femoris and hamstrings and gastrocnemius
What are the three capsular ligaments of the hip joint + where are they located?
- Pubofemoral lig - anteriorly located
- Iliofemoral lig - anteriorly located
- ischiofemoral lig - posteriorly located
Name the 6 phases of the gait cycle
- early stance
- mid stance
- late stance
- early swing
- mid swing
- late swing
What is the hip doing during late swing?
- in flexion
- concentric activity of illiopsoas and rectus femoris
- eccentric activity of gluteus maximus and hamstrings
What is the ankle doing during mid swing?
In dorsiflexion ( clearance of toes) concentric activity of tibialis anterior
What is the ankle doing during late swing?
- in dorsiflexion to prepare for heel strike
- concentric activity of tibialis anterior and isometric activity of triceps surae for stability.
what is the knee doing during late swing?
In flexion but moving into extension to prepare for heel strike
- concentric activity of quadriceps femoris
What is the hip doing during early swing?
- in extension, moving into flexion
- concentric activity of illiopsoas and rectus femoris
- eccentric activity of gluteus maximus and hamstrings
What is the ankle doing during late stance?
- in full plantarflexion
- concentric action of triceps surae
What is the knee doing during mid swing?
- in flexion
- concentric action of gastrocnemius and hamstrings
What is the hip doing during early stance?
- flexion moving to extension
- concentric action of gluteus maximus and hamstrings
- eccentric action of illiopsoas and rectus femoris
Where does our line of gravity fall relative to our ankle joint?
anterior
What is the knee doing during early swing?
- in flexion
- concentric activity of hamstrings and gastrocnemius
What is the hip doing during mid swing
- in flexion
- concentric action of illiopsoas and rectus femoris
- eccentric action of gluteus maximus and hamstrings
What is the ankle doing during early swing?
- in dorsiflexion ( for clearance of toes)
- concentric action of tibialis anterior
Where does our line of gravity fall relative to our hip joint? What is the purpose of this
posterior- “pushes” joint into extension where ligaments are tight so joint becomes locked and muscles can relax
How are our ankles stabilised during bipedal standing?
- joint does not lock
- energy is consumed using the plantarflexors to stabilise
What is the ankle doing during mid stance?
- moving into plantarflexion
- concentric activity of triceps surae
What is the hip doing during late stance?
- in extension
- concentric action of gluteus maximus and hamstrings
- eccentric action of iliopsoas
What is the hip doing during mid stance?
moving into extension
- concentric action of gluteus maximus and hanstrings
- eccentric action of illiopsoas
What is the knee doing during late stance?
- in extension as ankle moves into full plantarflexion
- concentric action of hamstrings and gastrocnemius
What is the knee doing during mid stance?
- moving into slight flexion
- concentric activity of gastrocnemius and hamstrings
What is the ankle doing during early stance?
- dorsiflexed but moving into plantarflexion
- concentric action of triceps surae
- eccentric action of tibialis anterior
