A cumulative dose metric capturing how much stimulation a PEMF device delivers to tissue each second. It counts both the rising and falling edges of every pulse. The body responds to field change, so each pulse delivers two induction events: one as the field rises and one as it falls. Total Stimulation Intensity adds them up and multiplies by how often the pulse fires. Calculated as (rise slew + fall slew) x frequency, expressed in G/µs·Hz. Higher values mean more cumulative biological stimulus per second. Distinct from Peak dB/dt, the single sharpest moment within one pulse.
A magnetic field that changes in time induces an electric field in the tissue it passes through. This is Faraday's law, and it is why the speed of the field change (the slew rate) matters more than the field's peak strength: a faster change induces a stronger electric field, which is what stimulates the body.
