This placebo coil has a design that does not indicate the active and placebo side, which is the best choice for advanced clinical research. The sham and active stimulation remain nearly identical in experimental manipulation, sound intensity, rhythm, and vibration, making it ideal for double-blind studies.
The coil doesn't need to change the side, it achives the sham/active stimulation by connection of IFM machine.
