An abductory twist is the sudden movement of the heel
An abductory twist is a characteristic of the way we walk that is often seen by clinicians. Many people when they are walking, just as the rearfoot comes off the ground there is a sudden and small motion of the rearfoot medially (abduction). Many podiatrists do not consider this to be of much significance because it is only a sign of an underpinning problem as opposed to a problem on its own.
There are many different causes of this abductory twist. The first is that the great toe or hallux joint needs to dorsiflex or bend just as the heel lifts up off the ground in order that we can move ahead. If that joint does not want to flex, then the foot will abduct to go around the block at the joint. Another frequent cause is overpronation of the foot. This is where the foot is rolling inwards at the rearfoot and the lower leg is externally rotating trying to roll the foot outwards. When the heel lifts up off the ground the foot abruptly abducts due to the twisting.
A medial heel whip is another entity that does get mistaken for an abdutcory twist, however they are completely different. The twist occurs as soon as the heel comes off the ground and the whip is more of a circumduction of the entire foot as it lifts up of the ground. While the twist and whip are in the identical direction, they are very different things and brought on by different problems.
The Abductory Twist twist doesn't have to be treated since it is no problem on its own. It is a result of something and that something is the reason for the problem, so that needs managing as opposed to just the abductory twist. The therapy will have to be directed at either the cause of a block in motion at the big toe or the cause of the overpronation of the foot. Consequently the therapy may take on a variety of possible alternatives, so there isn't any one strategy for it.
