Abstract: A shaped body (1) of plastic material with rounded outer contours is used for carrying out a method of active motion therapy by filling bulk material (11) of shaped bodies (1) into a container (12). The limbs (13) to be trained are immersed into the bulk material (11) and exercises are carried out. The shaped body (1) is symmetrical relative to a first plane defined by a first substantially oval outer periphery (U1) of the shaped body (1), asymmetrical relative to a second plane substantially perpendicular to the first plane and defined by a second substantially oval outer periphery (U2) of the shaped body (1), and asymmetrical relative to a third plane defined by a third outer periphery (U3) of the shaped body (1), 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.

Abstract: A balance training apparatus has replaceable and exchangeable inserts tailored to accommodate various uses and to demand balancing skills of the user in dependence on personal attributes of the user. A moving object is disposed within each of the inserts for directed motion by the balancing user. A window, preferentially made from a clear plastic material, provides for visual observation by the user of the moving object traveling through a respective insert path, such that the user can direct the moving object, preferentially a ball, towards a target or along a path. The window is attached to the house in a manner not requiring the use of tools, such that the user can easily remove the window for direct access to and exchange of the insert.
