(54) Therapeutic device


(57) A visual stimulation device for assisting in the lowering of a user's breathing rate by means of displaying a cyclical graphic representation on a display (6) comprising a grid of light emitting diodes (14). The representation comprises a bar graph adjacent bars of which are illuminated sequentially during a first display corresponding to user inhalation and extinguished during a seccnd display corresponding to user exhalation. A third display corresponding to a rest period between inhalation and exhalation may also be provided. The display is controlled by circuitry (18) including a first circuit (27) which computes the user's rest breathing rate from data input by the user in a relaxed state and a further circuit containing display duration ratio information. The duration ratio of the first to the second to the third displays is substantially 40%; 50%; 10% and the display cycle corresponds to the user's rest breathing rate in breaths per minute minus one.
