Method and apparatus are provided for therapeutic administration to body parts digitally generated electromagnetic fields with trapezoidal, square, triangular and sawtoothed and other complex temporal field waveforms that are microcontroller controlled for a range of amplitude, frequency, and dc offsets; the apparatus providing programmed sequences of radiation waveforms. Multiple electromagnetic antennas establish a variety of field configurations for exposure of various body parts in the treatment of a wide range of afflictions including exfoliation of calcium deposits causing improvements in arthritis and other rheumatic diseases--osteoarthritis, nervous interconnection (neuropathies), etc., the treatment of tremors and seizures, migraine, hypertension, lower back pain, urinary incontinence, and premenstrual tension. Temperature sensors within the antennas are provided to limit the temperatures therein.
