5. Peer-Reviewed Works Cited: Citation Index: Dr. Barkhaus’ works have been cited over 300 times in literature. Textbooks: Original and seminal research by Dr. Barkhaus has been cited over 80 times in current textbooks and reviews, particularly those in Clinical Neurophysiology and Neuromuscular Diseases. eMedicine Chapters: eMedicine is the world’s largest online, peer- reviewed medical reference. It is a unique publishing venture covering most major specialties. Though it is technically a textbook series, it is serialized like a journal to facilitate maintaining updates that are made on a regular basis. As of 2009, Dr. Barkhaus’ chapters 3 principal chapters have received >30,000 hits- refs 14,15,& 26.
6. Peer-Reviewed Educational Products: In 1997 I began working on what has become an exciting educational venture with my long-time collaborator. These became a series of “multi-media” books on DVD. To date I have co-authored three of these with the first being revised into a second edition (See pages 30 & 32 above, “Books, Chapters, Reviews”, references 5, 6, 12, 25). These were exciting but time-consuming projects that integrated a large corpus of material into various aspects of clinical electromyography. Although a few others have attempted to compete, our projects still stand out in quality and technical expertise. The “Myoanatomy Atlas” has brought to life what used to be two dimensional drawings in books. It would be like comparing the written score of an opera in book form to a DVD recording of an actual performance with accompanying text and other visual aids. To date, these have been, or are being used, in almost a hundred academic centers/ training programs in electromyography in North America and at least other 50 countries. Mark B. Bromberg, MD wrote an extensive review of these DVD’s for Muscle Nerve, the premier journal in electromyography and the official journal of the American Association of Neuromuscular and Electrodiagnostic Medicine (2009;22(10)1468-1469). “Dr. Barkhaus is a clinical electromyographer with extensive experience with quantitative EMG and electrode recording characteristics….. They bring an extraordinary amount of experience to these DVDs. They are very good and clear teachers…. All in all, I found the method of live presentation very effective…. Drs. Nandedkar and Barkhaus are pioneering a new medium to teach electromyography. It is like having a private tutorial with an experienced engineer and clinician, with a complete spectrum of patients…... I highly recommend this for all teaching programs, for any trainee, and for anyone who wishes to improve their skills.”
