A method for treatment of nerve function comprises obtaining a preferably both electrically powered and portable treatment apparatus capable of contacting, via a treatment head, a target area of a patient and introducing low-pressure suction, i.e. negative pressure flow, thereto, configuring the treatment apparatus so as to introduce predefined, advantageously, pulsating pressure variation to a suction opening arranged at the treatment head, and applying the suction opening of the treatment head on the target area while the treatment apparatus is on and providing the suction effect corresponding to the configuration.
