Abstract: An apparatus for determining the location of receptor regions including a nuclear resonance tomograph and an indicator device for the skin sites located directly above the receptor regions. The indicator device is in the form of one or more, preferably non-magnetic, indicator elements which can be placed on the skin, or a light marker device connected with the display unit of the nuclear resonance tomograph. The light marker device places a mark on the skin site located above the measurement area.

Abstract: The puncturing stimulation needle has an insertion part (2) and a holder part (3). The insertion part (2) is structured as a screw with one or more threads, the thread height (6) of which is greater than twice the diameter (7) of the insertion part (2) at its thickest point. Preferably, the holder part (3) is structured in the form of a ring or small disk, with its side facing the insertion part (2) lying in a plane approximately perpendicular to the geometric axis of the insertion part. The puncturing stimulation therapy apparatus has a portable, battery-powered treatment current generator (17), with at least one electrode (23, 24) in the form of a puncturing stimulation needle being connected with the generator via a flexible line (21, 22), with this needle having an insertion part (2) which is shorter than 4 mm, and a holder part (3) in the form of a ring or small disk. A surface electrode (29) can also be provided at the housing of the treatment current generator (17).
