Event Description

Information was received from a consumer regarding a patient with an implantable neurostimulator (ins).It was reported that the controller was not working properly.About a week prior to the report, the intensity started nearly doubling on its own without the patient doing anything.For example, the device was set at 4.7, but it went up to 7.8.Stim was turned back down to 4.7 three separate times and it scared the patient.Stim was so strong that he had to hold on to something or else it knocked him over.It was reviewed it was unlikely caused by the controller.The patient didn't think he had adaptive stim.A rep was going to follow up with the patient.No further complications were reported.
