Systemic is for the whole body/mind or long term treatment for a long standing condition or issue. ie. Depression use feel good systemic 3-4 times a week for a longer time.

Acute is for intense, immediate responses ie. sprained ankle, bee sting, recent bad news etc. You could use the one program three times in one day for pain with electrodes. Acute programs only run one frequency, so they are not IMF programs and don’t need to use the quantum sensor.
