It was reported the essential tremor patient experienced ¿shocking sensations and paresthesias¿ in his left arm, torso, and leg with the sensations ¿not limited to a specific location.¿ the patient reportedly ¿could induce the sensation when pressing onto the implantable neurostimulator (ins),¿ however sometimes the shocking sensations would also occur ¿without any external influence.¿ the patient additionally experienced ¿intermittent stimulation,¿ whereby the patient¿s tremors ¿reoccurred regularly, as if the ins was turned off.¿ it was stated the patient experienced ¿less than 50% therapy relief¿ on his left side.These tremors would occur ¿sometimes for several hours.¿ the tremor would then ¿disappear on its own later, as if the stimulation was turned back on.¿ it was noted the patient lost his paresthesia and therapy within 24 hours of having his ins interrogated with a physician programmer at the time of report.Impedance testing was performed and found ¿fine¿ impedance values.X-ray imaging ¿didn¿t show any anomalies in the extensions/leads.¿ the patient¿s stimulation was reprogrammed to a bipolar stimulation setting in an attempt at troubleshooting the situation; however, it was noted that ¿even with the bipolar stimulation there was a shocking sensation when touching the ins.¿ the patient¿s ¿stimulation was still intermittent¿ and a revision surgery was planned for the patient as of 16 days after initial report.Additional information was requested; a supplemental report will be filed if additional information is received.
