Q

Where does our line of gravity sit relative to our knee joint + what is the purpose of this?

A

anterior- pushes joint into extension and ligaments are tight so joint is locked

Q

What is the Knee doing during early stance?

A 
In extension (locked for stability)
- isometric action of quadriceps femoris and hamstrings and gastrocnemius

Q

What is the ankle doing during late swing?

A
  • in dorsiflexion to prepare for heel strike

- concentric activity of tibialis anterior and isometric activity of triceps surae for stability.

16
Q

What is the ankle doing during early swing?

A
  • in dorsiflexion ( for clearance of toes)

- concentric action of tibialis anterior

17
Q

Where does our line of gravity fall relative to our hip joint? What is the purpose of this

A

posterior- “pushes” joint into extension where ligaments are tight so joint becomes locked and muscles can relax

18
Q

How are our ankles stabilised during bipedal standing?

A
  • joint does not lock

- energy is consumed using the plantarflexors to stabilise

19
Q

What is the ankle doing during mid stance?

A
  • moving into plantarflexion

- concentric activity of triceps surae

20
Q

What is the hip doing during late stance?

A
  • in extension
  • concentric action of gluteus maximus and hamstrings
  • eccentric action of iliopsoas
21
Q

What is the hip doing during mid stance?

A

moving into extension

  • concentric action of gluteus maximus and hanstrings
  • eccentric action of illiopsoas
22
Q

What is the knee doing during late stance?

A
  • in extension as ankle moves into full plantarflexion

- concentric action of hamstrings and gastrocnemius

23
Q

What is the knee doing during mid stance?

A
  • moving into slight flexion

- concentric activity of gastrocnemius and hamstrings

24
Q

What is the ankle doing during early stance?

A
  • dorsiflexed but moving into plantarflexion
  • concentric action of triceps surae
  • eccentric action of tibialis anterior
