A faster-changing field has been linked to a stronger response
Published researchThe report leads with slew rate and Peak dB/dt, because they relate most directly to the stimulus tissue actually feels.
Where it appears in the report: Slew Rate, Peak dB/dt Analysis
The evidence
A controlled study found that a higher-slew-rate signal improved bone consolidation and shortened daily session duration compared with a classic signal. That backs the idea that rate of change is the primary driver. A separate small-animal study put the minimum effective slew rate near 0.10 G/us for bone. These point to the direction of the effect, and they don't pin down a single optimal value.
