Abstract

Wrist walking, which is characterized by the fact they are practiced in the internal stumps of the lower extremities peripheral regiments in the form of a circular sector through which protrudes an elastic rod that crosses the corresponding stump and is properly anchored by one of its ends on an opposite point of the periphery of the same, extending inside the body of the wrist to establish stop at its upper end against a fixed part of the body itself or the head coupled to it, while the lower stop. It establishes the upper end of the aforementioned races of the stump, coinciding with which a lug is provided in the throat coupling of the leg to the body of the wrist, which is guided by a slot made in the latter, which limits the rotation of the wrist. The leg from the straight or straight position, where it is normally maintained by the tension of the elastic rod and the position of the lug against the upper end of said groove, up to a bending position limited by the position of the lug at the opposite end of the leg. The same slot, in which the aforementioned rod is loaded, which automatically returns the leg to the previous position when the pressure exerted alternately by the user on the wrist in the direction of travel ceases, the leg being able to adopt the seated position or another any that allows the length of the race of the internal part of the stump and the consequent slack in it of a lower part of the elastic rod.
