ABSTRACT:
A method and apparatus for electrical dosimetry control in the application of electric currents to the human body, dosage being determined by the product of time and electrical current, wherein electrical current magnitude and/or time may be selectively varied by the patient or therapist during an administration procedure, for the comfort or convenience of the patient, without altering the total predetermined dosage to be administered, the system typically including means for setting the desired total dosage to be administered, means for selectively varying the magnitude of electrical current applied to the patient, means for integrating the applied current over time to obtain an electrical current-time product providing a running measure of dosage during the administration procedure, means for comparing the running measure with the total dosage desired, and means for terminating the administration procedure once the desired total dosage has been delivered to the patient.
