Monitoring for side effects that impact speech and balance is critical for the best results after adjusting stimulation

Sierra’s experience with DBS began in 2000 where she received movement disorders and DBS training from Dr. Monique Giroux, a fellowship trained movement disorders neurologist  in Seattle, WA.

Sierra worked with leading neurology and neurosurgery DBS experts while at the Cleveland Clinic. Sierra is highly proficient in managing stimulation for people with Parkinson’s, Dystonia, Tremor and has experience adjusting stimulation for people with Multiple Sclerosis, Tourette’s, Chronic Pain, Traumatic Brain Injury, Tourette’s Syndrome, and Minimally Conscious State. These medical conditions include experience with the following brain targets include STN, GPi, GPE, VIM, VC, ILN-CM/PF, VOA/VOP, H-Fields, Zona Incerta, and PVG/PAG.

Since 2004, she has managed a DBS troubleshooting clinic to evaluate patients who are dissatisfied with their DBS outcome, feel worse after DBS surgery, have stimulation side effects or have poor results from DBS. Her DBS research and publications focus on improving the care of patients with DBS and a special interest in neuroethics. Sierra offers her expertise to teach others about the clinical application of DBS programming techniques and is presently Assistant Clinical Professor at the University of Colorado School of Medicine.

Passion for Troubleshooting DBS Problems

Searching for the cause of poor results after DBS surgery has become the focus of my career in neurology. Patients deserve a second or even third opinion when DBS fails to perform. Helping patients’ put their mind at ease, shinning a light on poor programming or taking the next step in corrective surgery is much more than a job, it reveals my compassion for the highest quality of life for my patients.
