Clinical Neurophysiology

Electromyography (EMG) Section, NINDS

Tanya Lehky, M.D.

The EMG Section engages in collaborative clinical research on peripheral and neuromuscular disorders. The section carries out nerve conduction studies (NCS), electromyography (EMG), transcranial magnetic stimulation (TMS) and autonomic screening studies to diagnose and characterize patients with a wide spectrum of disorders. In addition to its primary mission to provide testing for clinical diagnosis, the section carries out advanced neurophysiologic testing for the characterization of newly discovered disorders and engages in research on electrodiagnostic outcome measures for clinical trials, such as motor unit number estimation (MUNE) and central conduction time measurements.

Faculty Information: Capt. Lehky, M.D. is a Commissioned Corps officer in the EMG Section of the Office of the Clinical Director, NINDS. She completed her medical degree at Georgetown University in 1985, followed by residency training in Internal Medicine at Children's Hospital of San Francisco and in Neurology at the University of Maryland. From 1991-1995, she participated in a clinical fellowship training in the Neuroimmunology Branch, NINDS; in 2000, Dr. Lehky completed an EMG fellowship in the EMG Section, NINDS. After serving as a staff neurologist at the National Naval Medical Center for several years, she returned to NINDS and has been directing the Clinical EMG laboratory since 2006. Dr. Mary Kay Floeter (Chief, EMG Section) continues as an active faculty member within the section.

Electroencephalography (EEG) Section, NINDS
Sara Inati, M.D.

The EEG Section engages in collaborative research to better understand the pathophysiology of epilepsy, as well as to advance the evaluation and treatment of patients with medically refractory epilepsy. In close collaboration with the Clinical Epilepsy Section and the Surgical Neurology Branch, this section seeks to use neurophysiologic and neuroimaging techniques to improve the ability to localize epileptic foci in preparation for possible surgical resection. The section uses EEG, including noninvasive and invasive long-term monitoring, electrocorticography, intracarotid sodium amobarbital procedure (WADA test), and magnetoencephalography (MEG). The section is planning a study using a combination of EEG, fMRI and MEG to assist in localizing epileptogenic foci, describe abnormal networks of activity, and possibly compare results in terms of the evaluation of language and other cognitive functions.
The EEG Section provides support to intramural NIH investigators from all institutes and centers, both through the techniques mentioned above, as well as evoked potentials, intra-operative evoked responses and polysomnography.  

Faculty Information: Dr. Sara Inati is the Chief of the EEG Section of the Office of the Clinical Director, NINDS. She completed her undergraduate studies at Harvard College, and went on to receive her M.D. with honors from Dartmouth Medical School in 2003. She subsequently completed her medical internship at Lenox Hill Hospital, and her residency training in neurology at the Neurological Institute at Columbia University Medical Center. She continued on for two years of fellowship training in epilepsy and clinical neurophysiology at the Columbia Comprehensive Epilepsy Center. In 2010, she joined the NIH as Staff Clinician with the neurology consult service then joined the EEG Section the following year. She is board certified in Neurology. Dr. Susumu Sato (retired) serves as an additional faculty member in the EEG Section, having previously served as Chief from 1983-2011.
