Answer 3

• 12.5º

Question 4

Postural control requires what 3 things

Answer 4

• Sensory function
• Sensory integration function
• Movement strategies

Question 5

Good postural control equals better _________

Answer 5

• Confinement

Question 6

Higher COP/COM displacement indicates relatively _______ control

Answer 6

• Poor

Question 7

Static versus dynamic balance

Answer 7

• Static: no intention to move, still moving though, & perturbations are internal
• Dynamic: could be “do this specific task” and could be “maintain balance despite…”
