PAIN REDUCING DEVICE Russian patent published in 1997 - IPC

FIELD: medicine; therapy; neuropathology. SUBSTANCE: patient is subjected to simultaneous effect of self-controlled relaxation of muscles checked by biological feedback and inactivation of trigger points by electric pulses the parameters of which are close to those of biopotentials of organs and tissues. Device has two groups of electrodes. Electrodes of first group serve as sensors of patient's muscle activity. Device has also amplifier, integrator connected to threshold member which is in its turn series-connected to multivibrator, infra-low frequency generator and to second group electrodes. Myosignal indicator is connected to threshold device input. EFFECT: improved therapy. 1 dwg
