(57) [Summary] [Problem] Even if there is a response difference or individual difference depending on patients receiving treatment such as analgesia or anesthesia, and even if the effect differs depending on the frequency and shape of the pulse wave. The present invention provides a low-frequency treatment apparatus capable of obtaining a sufficient treatment effect without previously investigating which pulse wave is effective for each patient. A low-frequency treatment device (100A) includes an electric pulse composed of a bipolar rectangular wave and at least 1 / A pulse generating means 1 for generating an electric pulse group of 25 to 500 Hz having an intermittent time of two cycles, an output-side electrode unit 60 connected to an output terminal of the pulse generating means 1, An input-side electrode unit 70 for detecting and measuring an electroencephalogram, and an effect confirmation unit 20 for confirming the effect of the administered pulse based on the detected electroencephalogram are provided. In this low-frequency treatment device, the electric pulse group is constituted by a rectangular wave pulse train of 5 cycles or less, and the pulse generation means is configured to be able to change the duration of the pulse and the intermittent time according to the patient. ing. |
