Device for carrying out an active motion therapy method and shaped body of such a device

A shaped body of plastic material with rounded outer contours is used for carrying out a method of active motion therapy by filling bulk material of shaped bodies into a container. The limbs to be trained are immersed into the bulk material and exercises are carried out. The shaped body is symmetrical relative to a first plane defined by a first substantially oval outer periphery (U) of the shaped body, asymmetrical relative to a second plane substantially perpendicular to the first plane and defined by a second substantially oval outer periphery (U) of the shaped body, and asymmetrical relative to a third plane defined by a third outer periphery (U) of the shaped body, which is substantially perpendicular to both the first and second planes. The shaped body effects a resistance to motion which is nearly independent of the exercising direction.
