Abstract [en]

A new device for generation of electromagnetic fields at extra low frequencies, to be used in fracture treatment, is described. The device involves a coil and a battery powered noise-generator. An alternating magnetic field of 4 × 10−4T (4 Gauss) (RMS value) with a frequency range 1–1000 Hz is generated. Results from a controlled randomized study of fresh fractures have shown significant differences (p < 0.01) between the treated group and the control group. The results are encouraging and motivate further investigations with this method.
