Answer 2

distal segment angulated away from body midline

Question 3

Static position

Answer 3

relative position of body segments

Question 4

Kinematics

Answer 4

Measures relative movements between adjacent bones

Position, velocity, acceleration

Question 5

Kinetics

Answer 5

Forces transmitted by muscles and tndons to bones

Force, energy and power

Question 6

Moment

Answer 6

Force x Distance

Question 7

Momentum

Answer 7

Mass x velocity

Question 8

If the foot is not well aligned with the ground the ground exerts a force on the joints which require increased ________ to keep the body stable?

Answer 8

moments

Question 9

Pronation - OKC

Answer 9

Abduction
dorsiflexion
eversion

Question 10

Pronation - CKC

Answer 10

Internal rotation of the leg

Plantar flexion with adduction of the hindfoot

Question 11

Supination - OKC

Answer 11

Inversion
Plantarflexion
Adduction

Question 12

Supination - CKC

Answer 12

External rotation of leg

dorsiflection and abduction of hindfoot

Question 13

STJ and MTP produce motion in how many planes?

Answer 13

Tri-plane motion

They are associated in function. Change in one joint affects the other

Question 14

What is important for weight bearing rotational equilibrium?

Answer 14

Ground reactive forces medial and lateral to STJ axis
