And a strength display section 35b and a cycle display section 35c. Next, the first treatment device 1 receives a reception antenna 10 for receiving a radio signal from the treatment device body 3, a reception circuit 11 for amplifying and demodulating the received radio signal, and an output signal of the reception circuit 11. A signal processing unit 12 for processing, a low-frequency pulse generation unit 13 for generating a low-frequency pulse for treatment, a control unit 14 for controlling each unit, a power supply unit 15 for supplying an operating voltage to each unit, and a low frequency And a conductor 16 for applying a low-frequency pulse generated by the pulse generator 13 to the human body. The conductor 16 is provided with a pair of electrodes E ₁ and E ₂ . The electrodes E ₁ and E ₂ are used in close contact with the treatment site of the human body M. Low frequency pulse generator 13

The first massager 1 is the first
The power-on of the treatment device main body 3 is detected by the data signal of 1., and the generation of the low-frequency pulse is started with reference to the timing of the synchronization signal detected subsequently.

The 2nd massaging child 2 operates similarly. Therefore, the low-frequency pulse generation timings of the first and second treatment elements 1 and 2 coincide with each other.

Here, when the power is turned on, it is assumed that the electric stimulus is set strongly and the cycle is set fast. In this case, the "strong" display blinks on the strength display portion 35b of the treatment device main body 3, and the "fast" display blinks on the cycle display portion 35c. From this state, if it is desired to change the electrical stimulation cycle later, the cycle switch 35e is operated.

In the first embodiment, the cycle and timing of the blinking display on the treatment device body 3 are independent of the generation cycle and timing of the low-frequency pulse in the treatment elements 1 and 2, but in the present embodiment, the cycle and timing are shown in FIG. They match, as shown. That is, the treatment device main body 3 is controlled so as to perform blinking display based on the transmission timing of the synchronization signal. Therefore, the generation cycle and timing of the low-frequency pulse and the cycle and timing of blinking display match,
