Further follow up indicated that the surgeons saw the fibrosis on the mri, and so they decided to perform new lead implantation.It was reported that sometimes the patient felts the stimulation because the muscle twitched.This is more a physiological process by the patient.The available programming history data was reviewed, this review showed that the diagnostic test was recorded only on two dates: on (b)(6) 2012 the impedance value was 1864 ohms and on (b)(6) 2012, the lead impedance was 3473 ohms.Those values support the reported fibrosis.Further attempts, to obtain more information about this incident, were unsuccessful to date.
