Apparatus for electrical stimulation, in particular for bruxism

A method for preventing bruxism of an individual in a period of time by application of electric stimuli in a randomly selected frequency, comprising the steps of:

• a. attaching at least one electrode assembly to the skin of the individual in a region effective to treat bruxism before occurrence of bruxism;
• b. providing an electric stimulus by a processing control unit as a packet, the packet having a pulse train with predefined parameters including:
• start current, end current, start voltage, end voltage, pulse width, pulse train duration, inter-pulse spacing, duty cycle of each pulse, and pulse set spacing;
• c. applying the electric stimulus to the region by the at least one electrode assembly attached to the skin of the individual for relaxation of at least one of a masticatory and/or facial muscles of the individual, wherein the processing control unit is not processing monitoring signals;
• d. randomly selecting by the processing control unit a packet frequency between 0.001 and 1 Hz, where the packet frequency is defined as a rate of packets during the period of time, where a time duration between two packets in the period of time defines an inter-packet interval;
• e. at an end of the inter-packet interval, providing the electric stimulus with the predefined parameters in b and repeating c;
• and
• f. repeating d and e until the period of time ends;
• whereby the electric stimuli are provided to the individual where the processing control unit is not processing monitoring signals during the period of time, such that the application of the electric stimulus results in relaxation of at least one of the masticatory and/or facial muscles of the individual, thereby preventing the bruxism before occurrence of the bruxism.
