ABSTRACT:
A low-frequency treatment device includes electrodes to which a low-frequency pulse signal is supplied so as to apply an electric stimulus to a living body; a section for presetting a number of times of muscle contraction which occurs by applying the electric stimulus; a section for setting a pulse signal conducting time period and a pulse signal pausing time period in an interval; a section for computing a treatment time period based on the number of times of muscle contraction and on the conducting and the pausing time periods; a timer which starts counting a time period when supply of the pulse signal is started, and transmits a stop signal for stopping the supply of the pulse signal when the counted time period reaches the computed treatment time period; and a device for shutting off a circuit for supplying the pulse signal based on the stop signal.
