Event Description
It was reported that the patient went into the clinic for a follow up visit.They said their left body had worsening symptoms such as a wearing off with worse tremors.They felt electric shocks sometimes too.The patient stated that they fell down last month and believed to be a cause or contributing factor.The impedance measurements for their right stn had high impedances: monopolar - c<(>&<)>8 = 2711, c<(>&<)>9 = 3237, c<(>&<)>10 = 5174, c<(>&<)>11 = 10.2k.Bipolar -  8<(>&<)>10 = 4468, 8 <(>&<)>11= 9619, 9<(>&<)>11 = 8156, 10<(>&<)>11= 5368.Only some bipolar were ok such as 8<(>&<)>9=1995, 9<(>&<)>10=2711. however, the patient used monopolar 10 as setting; c+10-,amp4.5v, pw60, rate130.Therapy impedance showed high while current can¿t be determined.The physician decided to change their settings by using bipolar 9<(>&<)>10 that had a normal electrode impedance as below setting; 10-9+, amp5.0v, pw60, rate130 therapy impedance=2521 current=2.0 ma.The physician also adjusted the medications, but it was unknown if the issue was resolved.There was no surgical interventions that occurred.
