The drive device has an electric motor unit, at least some sections of which are operatively connected either directly or indirectly to the wall in order to generate a massaging motion. A control assembly, which is connected to the electric motor unit, is provided to control the intensity of the massaging motion. The current electric power draw of the at least one electric motor unit is advantageously determined periodically or continuously, the electric power draw that has been determined is compared to at least one predefined reference power value and the intensity of the massaging motion is controlled depending on the result of said comparison. ## Claims ### Claim 1 A method for controlling intensity
