As explained on the "Frequency" page, a PEMF therapy session should be sufficiently long in order to be effective.
PEMF therapy devices using only one specific pulsing frequency, e.g. like 25 Hz for the complete therapy time require multiple PEMF sessions several times daily for 8 to 15 minutes. This is because the body adapts to a specific pulsed frequencies and make as such longer lasting therapy times ineffective.
E.g. when we sre in a plane we experience noise made by the motors of the plane. After a short while we hardly notice this noise anymore. This is due to the ability of our body to 'adapt' to the surrounding noise disturbances and thus 'cancel them out'.
The same happens with PEMF if pulsed the whole therapy session with the same frequency and intensity, which are such 'disturbances' for the human body.
The body adapts to the used pulsed frequency and after a few minutes the therapy effect decreases. By changing the PEMF pulsing frequency every few minutes, this adaptation effect is avoided and effective PEMF therapy is obtained during the complete therapy session, not dependent on the total therapy time while the pulsed frequencies are sufficiently separated for each time step.
This is the reason why the Curatron PEMF devices have ten different programs in the units themselves. Each program contains of a series of different and changing pulsed frequencies and intensities. These programs run automatically in sequence during the total therapy session time. Each PEMF program has their own therapy time sequence, resulting in beneficial therapy efficacy for each of the chosen PEMF program. This results in effective PEMF therapy for the full time during the running time of the chosen program.
