Content: Rearfoot Leg Orientation - Normal (4)
- Lower leg vertical
- STJ neutral
- Calcaneus on surface
- MT heads on surface
T/F: The Calcaneus and MT heads are perpendicular in normal rearfoot alignment.
True
Q: How is rearfoot varus compensated for?
STJ Pronates and calcaneus vertical
Q: How is an forefoot varus compensated for?
STJ pronated, everted calcaneous, forefoot on surface
Content: Gait associated with Rearfoot varus (3)
- Heel strik and WB with excessive pronation
- Increased tibial IR
- Delayed tibial ER
Content: Gait associated with Forefoot varus (3)
- Excessive mobility in midstance and propulsion
