Abstract: The present invention provides an electrotherapeutic apparatus that produces a signal that, upon application to a patient, is exponential in character. The signal includes a relatively low-frequency, constant amplitude, periodic-exponential signal for muscle stimulation. Further, the signal preferably includes a relatively high-frequency, periodic-exponential signal for sensory stimulation.

Abstract: The present invention involves a method of treating a patient by providing a signal that is exponential in character to the patient. The signal, includes a relatively low-frequency, constant amplitude, periodic-exponential first component. Further, the signal preferably includes a relatively high-frequency, periodic-exponential second component. The present invention also includes a method and apparatus for non-invasively applying an electrical signal to a structure associated with the eye of the patient. The signal is provided to the structure associated with the eye in the preferred embodiment of the invention by positioning a device for conducting the electrical signal at a point on the exterior of the patient that is substantially interior to the bone structure defining the eye socket. Preferably, the electrical signal is shaped such that an electrical charge is imparted to one or more structures associated with the eye.
