Normal Foot Pronation - Observed in the Plantar grade foot
Also referred to as: Hip Drive Pronation

Normal (Hip Drive) Foot Pronation. Stance phase Foot motion (pronation/ supination) is driven by the Clockwise, Counterclockwise rotations of the pelvis :

• Clockwise rotation of the pelvis, pronates the left foot, supinates the right foot
  
• Counter-clockwise rotation of the pelvis, pronates the right foot, supinates the left foot

Gait Analysis - Right Foot

From Heel Strike to Flat Foot, the pelvis is rotating Counter-clockwise (See Animation Below)

• This Counter-clockwise rotation pronates the right foot.
  
• Foot pronation unlocks the forefoot and allows it to adapt to uneven ground surfaces.

From Flat Foot to Heel Lift, the pelvis is rotating Clockwise (See Animation Below)

• This Clockwise rotation supinates the right foot.
  
• Foot supination locks the forefoot and allows it to function as a rigid lever at Toe (Push) Off (Zitzlesperger, 1960).
