ABSTRACT OF THE DISCLOSURE


An electro-magnetic low frequency therapeutic
system comprising a magnetization coil for creating an
electro-magnetic field in response to a preselected treat-
ment signal whereby the magnetic field has a desired treat-
ment characteristic. The magnetic field has an adjustable
intensity set by adjustable control means. The control
means also is provided with circuit means for controlling
the peak amplitude of the field for achieving a specific
modulation of the peak amplitude in a given time. The
control means further has means to select the orientation
and/or direction with respect to a tissue to be treated.
Still further, the control means has circuit means to select
the repetition frequency, either pulsating or sinusoidal, fed
to the magnetization coil to obtain a selected one of dif-
ferent therapeutic signals. Still further, the control means
is provided with means to select a desired treatment time.
An automatic demagnetizing means is also provided and res-
ponsive to a preselected demagnetizing time and mode for
attenuating the field in a desired manner to terminate a
magnetic field treatment.
