Patent ID: 7769463

Claim:
A therapeutic electrostimulation apparatus for use in a treatment session having first and second portions, the apparatus including in combination: a source of bipolar pulses of a first predetermined frequency; first, second and third amplitude control circuits each having an input and each having an output, with the inputs of the first, second and third amplitude control circuits coupled to the source of bipolar pulses at the first predetermined frequency; a first source of modulating control signals to yield a first modulating frequency which is less than the first predetermined frequency; a second source of modulating control signals to yield modulating frequencies at the first modulating frequency and a second modulating frequency; a third source of modulating control signals to yield modulating frequencies at the first modulating frequency and within a diapason of third modulating frequencies; the first source of modulating control signals coupled with the first amplitude control circuit to cause the amplitude of bipolar pulses in successive groups of bipolar pulses to vary in accordance with a predetermined asymmetrical pattern at the first modulating frequency throughout the first and second portions of a treatment session; a first set of output electrodes coupled with the output of the first amplitude control circuit for use as transcranial electrostimulation output electrodes; the second source of modulating control signals coupled with the second amplitude control circuit for modulating the output of the second amplitude control circuit with the first modulating frequency during the first portion of a treatment session and with the second modulating frequency during the second portion of a treatment session; a second set of output electrodes coupled with the output of the second amplitude control circuit for use as spinal cord electrostimulation output electrodes; the third source of third modulating control signals coupled with the third amplitude control circuit for modulating the output of the third amplitude control circuit with the first modulating frequency during the first portion of a treatment session and with frequencies within the diapason of third modulating frequencies during the second portion of a treatment session; and a third set of output electrodes coupled with the output of the third amplitude control circuit for use as peripheral area electrostimulation output electrodes.
