The condition of being prone; the act of assuming or of being placed in a prone position; a specific rotational motion of the forearm that moves the palm into a downfacing position, a specific rotational motion of the foot in which the plantar surface is rotated outward. pronation of foot eversion and abduction of the foot, raising the lateral edge. pronation of forearm rotation of the forearm in such a way that the palm of the hand faces backward when the arm is in the anatomic position, or downward when the arm is extended at a right angle to the body.
Usually used in relation to describing the posture of the feet. Pronation of the feet is the position where the inner side of the foot is lower than normal, or 'flat feeted'. This can cause the shins to rotate inwards, produce a knock kneed position which can lead to posture related problems with the lower limbs and back.
The motion of the foot as it spreads and arch collapses as far as it can to the ground, absorbing incoming shock and preparing the foot to propel itself. Technically speaking the foot is moving in three directions simultaneously in each of the 3 areas of the foot itself. The rear or hind foot (comprised of the heel and ankle bones). The mid foot (comprised of the tarsal bones ) and the fore or front foot (comprised of the metatarsals and phalanges). For those interested in the technical aspect of pronation read further. The areas of the foot revolve about two axis' of the foot ( see image) and while each of the areas has all the components of pronation and supination, certain areas have greater motion in one or more of the components of pronation than the other.
This is a rather complex three dimensional movement of the foot and ankle. It involves the turning out of the sole of the foot (eversion) and a movement away from the midline of the body (abduction). In technical terminology it is often referred to as dorsiflexion of the ankle joint. Pronation is usually apparent in the final phase a running stride, prior to pushing off, and is considered natural. In your video analysis you look only at a simplified two dimensional representation of this movement in the form of the angle that can be drawn between the leg, the ankle, and the heel of the foot. This angle is related to a "natural" or calibration angle of this complex at a normal standing state. Pronation is usually expressed as a negative angle relative to the calibration angle.
Pronation begins immediately after the heel contacts the ground. It is a normal and necessary motion for walking or running. Pronation is the distinctive, inward roll of the foot as the arch collapses.
Internal rotation along the long axis of the foot (between the second and third metatarsal). A complex combination of abduction, eversion and dorsiflexion. It is acceptable to view pronation in weightbearing as a simple â€œrolling inâ€ of the foot, at either the rearfoot or midfoot.
Rotation of a limb toward the midline of the body; turning the palm downward or flattening the arch of the foot; Pronation is a common foot problem which could predispose an athlete to injury; see orthotics.
An outward rotation or twisting of the heel bone accompanied by a depression and inward falling of the long inner arch and an abduction/eversion of the forefoot. A mild degree of this is normal on weight bearing.
The natural, inward roll of the foot; pronation begins when heel contacts the ground, the foot then rolls inward to absorb shock and transfer weight to the ball of the foot as it prepares to push off. It is a natural and necessary motion for running and walking.
The natural inward motion of the foot after heel strike and before pushing off again with the ball of the foot. Overpronation is excessive inward motion and can lead to running injuries. Learn how to choose running shoes.
In the foot, it is a combination of motions resulting in a position such that the foot is abducted and everted. Foot pronation can be a by-product of an arch problem, leg length discrepancy, or chronically bad running mechanics; can be compromised with the use of an orthotic. In the hand, pronation is movement of the forearm into a palm down position.
