Kenneth Heilman Kenneth Heilman, MD  <>  Dr. Heilman, who was the initial Medical Director of the BRRC when it was first funded by the VA in 1999, is an Air Force Veteran who served in Vietnam as well as a world-renowned neurologist. He was recently recognized by the VA Office of Research and Development (ORD) as a VA Researcher Who Served. In an interview about this, Dr. Heilman noted that the “most important motivational factors are finding joy in learning, being curious and showing an eagerness to investigate, working hard and persisting until you are successful, having empathy, and trying to make the world a better place.” That is also a great description of what it takes to pursue the difficult task of learning how to harness the brain’s neuroplasticity to restore the most function for the most Veterans in the least time when they are impaired by neurologic illnesses or diseases such as stroke or traumatic brain injury. The complete interview of Dr. Heilman is available at this link to the April 10, 2018, edition of VA Researchers Who Served at the VA ORD website. (April 2018)

Kay Waid Ebbs Kay Waid-Ebbs, PhD  <>  A recent publication that Dr. Waid-Ebbs co-authored describes a study that compared two ways of determining level of participation in Veterans with mild traumatic brain injury: Community Reintegration of Service Members (CRIS) and the Participation Assessment with Recombined Tools-Objective (PART-O). Data showed that the CRIS has greater potential to detect a change in participation but has a much greater administrative burden. Although authors recommended CRIS be used instead of PART-O, “a short form of the CRIS could be useful if it maintains psychometric performance while decreasing administrative burden.” This work is important because, “when implementing patient-centered interventions, how people perceive their limitation and their satisfaction are crucial for setting rehabilitation goals.” Link to PubMed abstract: https://www.ncbi.nlm.nih.gov/pubmed/28583464.  (Feb 2018)

David J. Clark David J. Clark, ScD  <>  Dr. Clark is first author on a publication he coauthored with students he has mentored and others on the challenge of adaptive walking ability in those with motor impairments. The perceived difficulty is the measure that is currently used, but that relies on self-report of those with impairments and is a subjective measure. Dr. Clark and his team showed that skin conductance on the palm of the hand has potential as an objective way to measure stress in this population. This is original and groundbreaking work because walking adaptation is required to deal with tasks like using stairs, picking up an object from the floor, or stepping over obstacles. In persons with motor impairments, these challenges have been linked to avoidance of community mobility and thus can decrease quality of life in Veterans with walking impairments caused by neurologic injury or disease.

Dorian K. Rose Steven E. Nadeau Dorian K. Rose, PhD, (left) and Stephen E. Nadeau, MD (right<>  A recent publication by Drs. Rose and Nadeau with others about research conducted to determine the effect of number of training sessions on rehabilitation outcome received kudos from the journal’s editor: “Understanding the optimal dose of a given therapeutic intervention (frequency, intensity, duration, and timing) is critical to the implementation of evidence-based physical therapist practice, and more research such as the work done by Rose et al is needed to inform clinical practice guidelines and the decisions that rehabilitation professionals and their patients make.” Link to PubMed abstract: https://www.ncbi.nlm.nih.gov/pubmed/29077960.  (Nov 2017)

Russell M. Bauer Russell M. Bauer, PhD  <>  Dr. Bauer, who has received numerous awards for teaching and student mentoring, has coauthored with two of his students and others an article on chronic traumatic encephalopathy (CET), or repetitive brain trauma, that was published in JAMA Neurology. The article includes a fascinating timeline graphic of notable events and publications in the history of CET research, which began in 1928 with a description of “punch drunk” clinical syndrome in retired boxers. The 2015 film, Concussion, was about the doctor who first discovered CET in a football player.  Dr. Bauer has been a mentor of Mr. Asken since 2014 and of Ms. Sullan from 2014 to 2016.  Full citation:  Asken BM, Sullan MJ, DeKosky ST, Jaffee MS, Bauer RM.  Research gaps and controversies in chronic traumatic encephalopathy: a review.

Portrait of Kevin K.W. WangKevin K.W. Wang, PhD  <>  Dr. Wang coauthored with a large group of investigators from all over the country an important paper on biomarkers of traumatic brain injury (TBI).  The paper was accompanied by an editorial noting:  “[These investigators] shine much-needed light (here, laser light) on a common neurologic conundrum, namely, how to determine who is hurt, who is healing, and who is healthy after head injury. . . . The technology advance [in this report] takes advantage of a novel laser-based bioassay with an unwieldly name: enhanced immunoassay multi-arrayed fiberoptics with rolling circle amplification (a-EIMAF).”  Full citation:  Rubenstein R, Chang B, Yue JK, Chiu A, Winkler EA, Puccio AM, Diaz-Arrastia R, Yuh EL, Mukherjee P, Valadka AB, Gordon WA, Okonkwo DO, Davies P, Agarwal S, Lin  F, Sarkis G, Yadikar H, Yang Z, Manley GT, Wang KKW et al.  Comparing plasma phospho tau, total tau, and phospho tau-total tau ratio as acute and chronic traumatic brain injury biomarkers.  JAMA  Neurol. 2017 Sep 1;74(9):1063-1072. The article is available at this link to JAMA Neurology.  (Sept 2017)

Portrait of Damon LambDamon Lamb, PhD  <>  Dr. Lamb is part of a joint project involving researchers at the Department of Veterans Affairs and the University of Florida that is funded under the "Targeted Neuroplasticity Training" program of the Defense Advanced Research Projects Agency, or DARPA.  They are investigating electrical stimulation of peripheral nerves to strengthen neural connections in the brain.  Dr. Lamb will be exploring which neural pathways in the brain are activated by stimulation of the vagus nerve and how that might enhance cognition.  Dr. Lamb noted that the BRRC also has related ongoing research specifically investigating how this approach might be used to improve symptoms of post-traumatic stress disorder in Veterans.  More details about the research can be found at this web page.  (April 2017)

Portrait of Mo H. Modarres, PhDMo H. Modarres, PhD  <>  Dr. Modarres has received a VA grant to study neuromarkers of traumatic brain injury and post traumatic stress disorder (PTSD) that he discovered.  The neuromarkers are derived by a sophisticated analysis of brain waves recorded by electroencephalography during sleep by means an automatic, computerized algorithm.  Dr. Modarres has filed a patent as sole inventor for the method of obtaining the neuromarker for PTSD. (March 2017)

Carolynn Patten, PT, PhDCarolynn Patten, PhD  <>  Dr. Patten was induced by the American Physical Therapy Association (APTA) as a Catherine Worthingham APTA Fellow (FAPTA) during a ceremony at APTA’s annual conference in June 2016 in Nashville, Tennessee.  The Fellowship recognizes significant contributions to the field of physical therapy through leadership, influence, and achievements for over 15 years. More information about the award is available at this page of the APTA website. (June 2016)

Stephen E. Nadeau, MD Stephen E. Nadeau, MD  <>  Dr. Nadeau will chair a symposium at the 44th Annual Meeting of the International Neuropsychological Society (INS) in Boston in February. As author of the book, The Neural Architecture of Grammar (MIT Press), in which he laid out his comprehensive, neurally-based theory of language function, Dr. Nadeau will bring that expertise to bear in chairing the symposium: Chaotic Order, Language Connectivity, and a Generalizing Treatment of Aphasia. Aphasia, an impairment in any form of language use caused by brain injury or illness, often severely affects the ability to communicate, which can be devastating.  Stroke alone causes aphasia in approximately 80,000 persons each year.

Russell M. Bauer, PhD, ABPPRussell M. Bauer, PhD, ABPP   <>   For his work at the University of Florida as Director of Clinical Training for the Department of Clinical and Health Psychology, Dr. Bauer received an award for Outstanding Service from the Council of University Directors of Clinical Psychology. Among other achievements, the award recognizes innovation in building and measuring program quality and achieving good outcomes for graduates. The BRRC has its own training program, the  Career Development Program funded by VA's Office of Research and Development. (August 2015)

Dorian K. Rose, PhDDorian K. Rose, PhD  <>  The American Heart Association has awarded Dr. Rose a $154,000 grant to study a novel rehabilitation intervention: a backward walking training program. Dr. Rose and her co-investigators, which include another BRRC investigator, Dr. Carolynn Patten, will examine the potential of this program to increase both mobility and self-efficacy of stroke survivors and thus improve their quality of life and decrease their risk of recurrent stroke. Self-efficacy is defined as what people believe about their ability to influence events that affect their lives (social learning theory). As part of a collaboration, the research will be conducted at Brooks Rehabilitation, a BRRC affiliate, in Jacksonville, Florida. (August 2015)

William M. Perlstein, PhD William S. Perlstein, PhD  <>  Dr. Perlstein’s innovative combination of direct-attention and metacognitive training for Veterans with traumatic brain injury (TBI) will be tested in a new VA research study. The 2-year study will assess the impact of his novel approach to rehabilitation on (1) cognitively complex activities such as activities of daily living and life participation and (2) neurocognitive abilities related to attentional control. Also, a form of electroencephalography (high-density, scalp-recorded brain electrical activity) will be used to assess changes in brain function during the study to determine if there are any neurological markers or signs of changes in the brain (neuroplasticity) that can be used to measure the results of this cognitive rehabilitation approach on brain function. (July 2015)

Janis J. Daly, PhD, portraitJanis J. Daly, PT, PhD  <>  An article reporting groundbreaking work Dr. Daly directed was published by the Archives of Physical Medicine and Rehabilitation.  In conjunction with the article, the journal also published an editorial about the significance of the article and a 12-minute interview with Dr. Daly about the work.  The study showed that arm and hand functions severely impaired by stroke can be significantly improved by intensive treatment, even if treatment begins more than 6 months after the stroke, when no further spontaneous recovery would occur.   The complete article is available here, and it was also featured in a recent BRRC newsletter (accessible version here). (June 2015)

Carolynn Patten, PT, PhDCarolynn Patten, PT, PhD  <>  Dr. Patten received the prestigious University of Florida (UF) Research Foundation Professorship for 2015-2018 and has also been named winner of the Linda Crane Research Award from the Florida Physical Therapy Association.  The UF award is based on recent research accomplishments such as publications in scholarly journals, external funding, honors and awards, and development of intellectual property.  The Linda Crane Research Award consists of a grant to conduct a clinical outcome study in any area of physical therapy that relates to the American Physical Therapy Association Guide to Physical Therapy Practice.  (April 2015)
