Kinematic Chain (EXAM 1)

Question 1

Purpose of Pronation in Walking

Answer 1

• Adaptation to terrain

- Dissipate ground reaction forces (shock absorption)

Question 2

Purpose of Supination in Walking

Answer 2

• Rigid lever for propulsion

- Provide stable base of support for LE weight transfer

Question 3

Stance Phase of Gait Cycle

Answer 3

• 60% of gait cycle

- Heel strike – foot flat – heel rise – toe off

Question 4

Swing Phase of Gait Cycle

Answer 4

• 40% of gait cycle

- Early (acceleration) – mid – terminal (deceleration) swing
