Body planes
•
Frontal plane motion is referred to as inversion (rotating a joint such
that the plantar surface of the foot points towards the other foot)
and eversion (rotating a joint such that the plantar surface of the foot
points away from the other foot). (These are sometimes incorrectly
called varus and valgus movements.)
•
Transverse plane motion is adduction (rotating the joint such that the
distal segment moves towards the other foot) and abduction
(rotating the joint such that the distal segment moves away from the
other foot).
Foot pronation and supination are now very common terms, widely
referred to by the public, particularly those involved in running. They
describe a specific combination of sagittal, frontal and transverse plane
motions and are best used to describe the movement of the foot as a
whole relative to the floor or leg.
