INTERFERENTIAL TREATMENT WITH MODIFIED BEAT FREQUENCY

An electrical interferential technique is used to determine operable treatment parameters which are then used to apply a treatment to a patient. A range of beat frequencies is applied to the patient and an indicator of autonomic nervous system activity is measured. When some degree of autonomic nervous system activity is detected, a subsequent trial is conducted using an overlaying range of frequencies, a narrower range or a single frequency, in an attempt to fine tune the reaction of the autonomic nervous system. The subsequent trial may use a different measure of activity of the autonomic nervous system. A garment having a series of electrode sites thereon may be used for a partially trained person to correctly apply electrodes to the patient's body. The treatments may be conducted while the patient is asleep.
