A method for providing a therapeutic benefit to a person is disclosed which includes a processor that executes a first function to determine a physiological parameter from one or more physiological sensors positioned on the person and then the processor executes a second function to determine at least one second physiological parameter from the one or more physiological sensors or an environmental parameter from one or more environmental sensors associated with the location of the person. Next, the processor uses either the first and second physiological parameters or the first physiological parameter and the environmental parameter to determine whether to apply bi-lateral stimulation to the person; activating first and second stimulators positioned bi-laterally on the person to initiate bi-lateral stimulation for a therapeutically effective time period when the processor determines to apply bi-lateral stimulation.
