“[S]inusoidal EMFs inhibit osteoblast proliferation while square EMFs promote osteoblast proliferation. While the square and serrated EMFs have no appreciable effects on osteogenesis, triangular and sinusoidal EMFs enhance the osteogenic differentiation and mineralization of osteoblasts, with triangular EMFs being the most potent waveform.” Based on 50 Hz exposures at 1.8 mT (18 G) —from Lanzhou, China.
