Complex movement

Question 1

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

Answer 1

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

Question 2

What is the Knee doing during early stance?

Answer 2

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

Question 3

What are the three capsular ligaments of the hip joint + where are they located?

Answer 3

• Pubofemoral lig - anteriorly located
• Iliofemoral lig - anteriorly located
• ischiofemoral lig - posteriorly located

Question 4

Name the 6 phases of the gait cycle

Answer 4

• early stance
• mid stance
• late stance
• early swing
• mid swing
• late swing

Question 5

What is the hip doing during late swing?

Answer 5

• in flexion
• concentric activity of illiopsoas and rectus femoris
• eccentric activity of gluteus maximus and hamstrings

Question 6

What is the ankle doing during mid swing?

Answer 6

In dorsiflexion ( clearance of toes)
concentric activity of tibialis anterior

Question 7

What is the ankle doing during late swing?

Answer 7

• in dorsiflexion to prepare for heel strike

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

Question 8

what is the knee doing during late swing?

Answer 8

In flexion but moving into extension to prepare for heel strike
- concentric activity of quadriceps femoris

Question 9

What is the hip doing during early swing?

Answer 9

• in extension, moving into flexion
• concentric activity of illiopsoas and rectus femoris
• eccentric activity of gluteus maximus and hamstrings

Question 10

What is the ankle doing during late stance?

Answer 10

• in full plantarflexion

- concentric action of triceps surae

Question 11

What is the knee doing during mid swing?

Answer 11

• in flexion

- concentric action of gastrocnemius and hamstrings

Question 12

What is the hip doing during early stance?

Answer 12

• flexion moving to extension
• concentric action of gluteus maximus and hamstrings
• eccentric action of illiopsoas and rectus femoris

Question 13

Where does our line of gravity fall relative to our ankle joint?

Answer 13

anterior

Question 14

What is the knee doing during early swing?

Answer 14

• in flexion

- concentric activity of hamstrings and gastrocnemius

Question 15

What is the hip doing during mid swing

Answer 15

• in flexion
• concentric action of illiopsoas and rectus femoris
• eccentric action of gluteus maximus and hamstrings

Question 16

What is the ankle doing during early swing?

Answer 16

• in dorsiflexion ( for clearance of toes)

- concentric action of tibialis anterior

Question 17

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

Answer 17

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

Question 18

How are our ankles stabilised during bipedal standing?

Answer 18

• joint does not lock

- energy is consumed using the plantarflexors to stabilise

Question 19

What is the ankle doing during mid stance?

Answer 19

• moving into plantarflexion

- concentric activity of triceps surae

Question 20

What is the hip doing during late stance?

Answer 20

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

Question 21

What is the hip doing during mid stance?

Answer 21

moving into extension

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

Question 22

What is the knee doing during late stance?

Answer 22

• in extension as ankle moves into full plantarflexion

- concentric action of hamstrings and gastrocnemius

Question 23

What is the knee doing during mid stance?

Answer 23

• moving into slight flexion

- concentric activity of gastrocnemius and hamstrings

Question 24

What is the ankle doing during early stance?

Answer 24

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