Event Description

A healthcare provider (hcp) reported that the patient is experiencing muscle spasms in their back which they believe is related to the patient's chronic parkinson's as of "years" prior to date notified.It was stated that the patient is also experiencing pocket paresthesia and burning as of about six months prior to date notified.The issue can be reproduced when turning the amplitude up over 3.5v, and the patient just had their implantable neurostimulator (ins) replaced on (b)(6) 2016 which didn't correct with impedances remaining the same.Group impedance measurements were taken results of 366 ohms and 8.1 ma, with the patient programmed at 2v, 60pw, 130hz, 2-, c+.There were no falls or trauma related to this event, and an x-ray was taken which did not show any issues.The patient's indication for implant is parkinson's dual and movement disorders.See related regulatory report 3004209178-2016-22436.

Additional information received from the hcp via the manufacturer representative (rep) reported that impedances of the lead were measured during revision on date notified which were found to be normal.There were no out of range measurements prior to surgery but were on the low normal range of 450-1300 ohms.The extension and ins were replaced at the request of the hcp, and following revision impedances were in the 900-2000 ohm range.It was stated that the physician assistant was concerned about the rate the ins had drained since the sep-(b)(4) as it had dropped to 2.96v, which is why the replacement was suggested.The issue was resolved at the time of additional information.See related regulatory report 3004209178-2016-22436.
