The design of a clinical electromagnetic bone stimulator.

The design and construction of an air-cored electromagnetic bone stimulator is described. The magnetic field waveform chosen has been based on that used for in vitro studies and is the one most commonly found in clinical practice. Detailed information on the circuitry involved, the waveforms and field strengths produced and the design of coils is presented. This should enable the stimulator to be constructed either for clinical use or to generate fields for laboratory evaluation.
