An apparatus for electrical therapies includes at least one electrocatheter, or an electroneedle, and at least one power supply device capable of electrically supplying the electrocatheter or electroneedle with at least one current suitable for carrying out at least one therapy. The apparatus includes at least one system for testing whether at least one desired point of application of the electrocatheter or electroneedle has been reached in the body of a patient. The testing system includes at least one device for emitting an electric testing current with which to electrically supply the electrocatheter or electroneedle before the start of the therapy, and at least one reading device, capable of providing at least one reading of at least one response generated in the patient by the electrostimulation with the electrocatheter or electroneedle through the testing current.
