The simple answer comes from our experience with small animals and horses. The placebo effect in all likelihood is not present in animals. The Curatron has an excellent track record with animals.
Most scientific clinical studies clearly show that in order to obtain clinical relevant results the minimum pulsing field strength must be at least 3-5 milli Tesla (30 to 50 Gauss).
In order to generate piezoelectricity inside bone and cells the field strength must exceed 10 milli Tesla (100 gauss).
There are different variations of large and expensive coil systems mounted on arms or beds, but none of these systems is able to generate energies higher than 100 gauss.
