Abstract

A biofeedback system including a plurality of switches, for example mercury switches, which can be positioned on a patient'"'"'s body and operatively arranged to respond to changes in orientation or position of a body member such as, for example, a patient'"'"'s hand, wrist and forearm. Circuitry is arranged to respond to the closing of respective ones of the switches and develop specific, distinct biofeedback signals, for example, individual audible and visual signals for respective switch closings. An additional plurality of switches of the same construction can be placed on a therapist and be operatively arranged and connected to demonstrate the movements and illustrate the nature of the feedback signals.

Claims

1. A biofeedback system comprising a plurality of sensing means which are to be removeably fixed to a patient for producing a corresponding plurality of respective signals in the response to change in position of portions of the body of the patient with respect to a given plane outside of the body of the patient and signal processing means coupled to said plurality of sensing means and responsive to the respective signals therefrom for developing different, sequential, distinctive signals which can be sensed by the patient and result from respective sequentially positioning of portions of the body of patient.

9. A biofeedback system according to claim 1 or 2, including a further plurality of sensing means which are to be removably fixed to a therapist for producing a further corresponding plurality of signals in response to change in position of portions of the body of the therapist, said signal processing means being coupled to said further plurality of sensing means and being responsive to signals therefrom for developing further sequential distinctive signals which can be sensed by the patient and result from perspective sequential positioning of portions of the body of the therapist.

10. A biofeedback system according to claims 1 or 2, including at least one additional sensing means which is to be removeably fixed to the patient, and additional signal processing means coupled to and responsive to signal from said at least one additional sensing means for providing at least one distinct signal in response to movement of said at least one additional sensing means.

11. A biofeedback system according to claim 10, wherein said additional signal processing means includes additional circuit means for producing at least one distinct audible signal in response to movement of said at least one additional sensing means.

12. A biofeedback system according to claim 10, wherein said additional signal processing means includes additional circuit means for producing at least one distinct visible signal in response to movement of said at least one additional sensing means.

13. A biofeedback system according to claim 10, wherein said additional signal processing means includes additional circuit means for producing at least one distinct visible signal and one distinct audible signal in response to movement of said at least one additional sensing means.

14. A biofeedback system according to claim 1 or 2, wherein said signal processing means are operatively arranged for respectively producing repetitive sequences of different distinctive siganls which can be sensed by the patient in response to repeditive respective sequential positions of portions of the body of the patient.

2. A biofeedback system comprising a plurality of force-of-gravity responsive sensing means which are to be removeably fixed to a patient for producing a corresponding plurality of respective signals in response to change in position of portions of the body of the patient with respect to a given plane outside of the body of the patient and signal processing means coupled to said plurality of sensing means and responsive to signals therefrom for developing signals which can be sensed by the patient, and wherein said signal processing means includes circuit means for producing different, sequential, distinctive signals which can be sensed by patient and result from respective sequential positioning of portions of the body of the patient.

3. A biofeedback system according to claim 2, wherein said circuit means comprises means for producing a sequence of different distinctive visible signals in response to respective sequential positioning of portions of the body of the patient.

4. A biofeedback system according to claim 3, wherein said means for producing a sequence of different distinctive visual signals includes a plurality of differently colored sources of light.

5. A biofeedback system according to claim 2, wherein said circuit means comprises means for producing a sequence of different distinctive audible signals in response to respective sequential positioning of portions of the body of the patient.

6. A biofeedback system according to claim 5, wherein said means for producing a sequence of different distinctive audible signals includes a plurality of generators each producing a distinctive different tone or musical note.

7. A biofeedback system according to claim 2, wherein said circuit means comprises means for producing a sequence of different distinctive visible signals in response to respective sequential positioning of portions of the body of the patient and means for producing a different distinctive audible signal in response to respective sequential positioning of portions of the body of the patient.

8. A biofeedback system according to claim 7, wherein said means for producing a sequence of different distinctive visual signals includes a plurality of differently colored sources of lights and said means for producing a sequence of different distinctive audible isgnals includes a plurality of generators each producing a distinctive different tone or musical note.
