Biofeedback apparatus for use in therapy
First Claim
1. Biofeedback apparatus comprising a computer system having an image display means viewable by a user of the apparatus, said computer system being programmed to provide on said image display means visual or pictorial representations of a body subject which gradually change in appearance depending on a physiological or psychological condition, a user input means comprising a sensor unit and a receiver unit, said sensor unit structured for attachment to a user, for sensing at least one psycho-physiological parameter of the user, and transmitting data sensed by the sensor unit to the receiver unit, said receiver unit structured to input the data received to the computer system;
- and means for changing said visual or pictorial representations based on changes in said data sensed substantially concurrently with the changes in the data sensed so that gradual change in the visual or pictorial representations corresponds to gradual change in the at least one psycho-physiological parameter of the user.

Abstract
Apparatus and a program designed to train the user to control one or more aspects of his or her psycho-physiological state is controlled by signals representative of a psycho-physiological parameter of the user, e.g. galvanic skin resistance. This may be detected by a sensor unit with two contacts on adjacent fingers of a user. The sensor unit can be separate from a receiver unit which is connected to a computer running the program. The apparatus is described for use in treating patients with a physiological condition, for example, irritable bowel syndrome. In a treatment session, one or more psycho-physiological parameters of the patient is sensed and the sensed parameter used to alter a display which the patient watches. The display includes a visual or pictorial representation of the physiological condition being treated which changes in appearance in a fashion corresponding to the physiological change desired in the patient.

7. Method of treating an undesired physiological condition of a person comprising
connecting the person to a biofeedback apparatus, said apparatus including means to sense at least one psycho-physiological parameter of the person and provide a visual or pictorial representations viewable by the person which correspond to a physiological condition to be treated in the person, said visual or pictorial representations gradually changing based on gradual changes sensed in the at least one psycho-physiological parameter; -
viewing of said visual or pictorial representations by said person; and controlling change in said visual or pictorial representations by said person providing a state of relaxation which affects the at least one psycho-physiological parameter being sensed to thereby cause said visual or pictorial representations to gradually change so that the physiological condition shown in the visual or pictorial representations correspond to a desired physiological condition.
