  • a situation in which a user operates the operation unit 30 without wearing the low-frequency therapy device 100 is, for example, a situation in which the user turns on the power or performs preliminary settings before wearing the low-frequency therapy device 100. In such a situation, it is highly likely that the user can see the operation unit 30. In addition, such a situation is highly likely to be a situation in which the user does not need to be concerned about the surroundings, such as a situation immediately before the user wears the low-frequency therapy device 100 at home.
  • the processor 21 performs operation feedback by supplying a notification pulse current when the low-frequency therapy device 100 is attached to the user, and performs operation feedback through an output device such as a display or speaker when the low-frequency therapy device 100 is not attached to the user.
