Electrostimulation device

An electrostimulation device that outputs an electrical signal comprising:

• an electric signal generator configured and/or programmed to output the electric signal;
• a control circuitry configured and/or programmed to control the electric signal generator;
• a set of electrodes configured and/or programmed to provide the output electric signal;
• and
• a power supply section configured and/or programmed to supply electric power to the electric signal generator and the control circuitry, wherein
• the electric signal is a repetitive output of a fifth electric signal, the fifth electric signal including:
• a first electrical signal having an amplitude that becomes larger from a first amplitude being non-zero,
• a second electrical signal having an amplitude that is maintained to a second amplitude being non-zero,
• a third electrical signal having an amplitude that becomes smaller to a third amplitude being non-zero, and
• a fourth electrical signal having an amplitude that is maintained to a fourth amplitude being non-zero, wherein
• each of the first electric signal, the second electric signal, the third electric signal and the fourth electric signal is a repeated alternating sequence of a pulse train, and said each of the first electric signal, the second electric signal, the third electric signal and the fourth electric signal having an off time where the pulse train is not outputted, and
• each pulse in each of the pulse trains is output at a first frequency value that is controlled by the control circuitry based on controlling the first frequency value,
• the first frequency value is swept between a second frequency a third frequency.
