BRRC 1999-1929:  30 years of Advancing Neurorehabilitation

Neurologic injuries or diseases such as stroke and traumatic brain injury (TBI) can impair not only motor control, but also cognition, sleep, and how emotions are expressed and experienced. One or more of these functions can be affected, but even a single functional impairment can significantly decrease quality of life and general health. Further, these impairments exact great financial and personal costs to a Veteran’s family and community as well as to the Veteran. 

Neuroplasticity is the ability of the brain to form new connections, which can be used to restore function.  How neuroplasticity works, however, is complicated and not fully understood. The BRRC is dedicated to discovering how to harness neuroplasticity to improve neurorehabilition with the goal of restoring impaired functions critical to quality of life—from mobility to sleep—in as many Veterans as possible and as quickly as possible for each Veteran.

2024-2029 BRRC Renewal  <>  The BRRC has been renewed for another 5 years! With this renewal, the BRRC will achieve 30 years of advancing neurorehabilitation through research on harnessing neuroplasticity and neural network reorganization by developing, testing, and implementing neurorehabilitation treatments for Veterans with cognitive, motor, and/or emotional neuropsychiatric impairments due to traumatic brain injury (TBI), spinal cord injury (SCI), and/or stroke. (September 2023)

Swanson Clayton Swanson, PhD  <>  Dr. Swanson, with a colleague from Colorado, reported that gray matter thickness of the motor cortex of the brain and inhibiting activity there were associated with ability of people with multiple sclerosis (MS) to turn their bodies. The data indicate that people with MS may rely on different neural resources to perform movements associated with fall risk.  From the article available in PubMed: Consistent with prior results demonstrating an association between the disease severity and cortical thickness of the motor cortex, our results further demonstrate motor cortex atrophy associated with specific characteristics of turning performance [provide] further evidence that motor cortex atrophy influences functional disability, specifically turning performance. (September 2023)

Waid-EbbsKay Waid-Ebbs, PhD  <>  Dr. Waid-Ebbs and her team reported on the results of one of her VA funded studies that showed precision neurorehabilitation holds significant promise for improving both cognitive function and quality of life for Veterans with mild traumatic brain injury or post traumatic stress disorder.  From the article available in PubMed:  We were able to administer treatment that was customizable, taking into account the constellation of symptoms for a given individual. Our results showed that  [precision neurorehabilitation] could address the unique complexities of mild TBI/PTSD while treating each individual.  (July 2023)

Otzel Dana M. Otzel, PhD   <>  Dr. Otzel is first author of an article on pharmacologic approaches to prevent muscle atrophy after spinal cord injury.

Dr. Otzel is a Career Development Awardee, a mentored grant for junior investigators. Two of Dr. Otzel's mentors are Drs. Bose and Yarrow of the BRRC. Read more here. (Feb 2023)


Bauer Williamson Russell M. Bauer, PhD (left), and John B. Williamson, PhD  <>  Drs. Bauer and Williamson each wrote a review on different neurologic conditions published in the same issue of Continuum, which was focused on Behavioral Neurology and Psychology. Continuum provides in-depth clinically-oriented reviews by experts in their fields for practicing neurologists, residents and fellows, and other neurology professionals. Stephen E. Nadeau, MD, and Kenneth Heilman, MD, both previous Medical Directors of the BRRC, also had reviews in the same issue. (Jan 2023)

Yarrow Otzel Joshua F. Yarrow, PhD (left), and Dana M. Otzel, PhD  <>  Drs. Yarrow and Otzel and coauthors published an article in the Journal of Applied Physiology about an association between bone loss and reduced blood flow after spinal cord injury (SCI). An image from that article was chosen for the Spotlight Cover of the journal. While the findings are not directly related to neuroplasticity, they have implications for SCI treatment. (Dec 2022).


Clark Otzel Rose David J. Clark, ScD (left); Dana M. Otzel, PhD (middle); and Dorian K. Rose, PhD (right)  <>  Drs. Clark, Otzel, and Rose and their postgraduate mentoree, Sudeshna Chatterjee, and others, including BRRC Director Emeritus, Janis J. Daly, PhD, coauthored an article published by Frontiers in Human Neuroscience that the journal selected as a “Motor Neuro- science Editor’s Pick.” The selection was based on substantial advances in addressing compelling problems.  Read more here. (Aug 2022)

Schiefer Matthew Schiefer, PhD  <>  Dr. Schiefer and his team authored an article published by Scientific Reports that is among the top 100 articles downloaded from the journal. The article reports on a new way to detect neural signals from the stomach that indicate fullness. The finding advances our understanding of obesity but may also advance the study of responses to neurorehabilitation. As noted in an email to Dr. Schiefer, Scientific Reports “published more than 3,460 neuroscience papers in 2021,” thus an article among the top 100 most downloaded is “an extraordinary achievement.Read more. (March 2022)

Kay Waid Ebbs Dorian K. Rose Kay Waid-Ebbs, PhD (left), and Dorian K. Rose, PhD (right<>  Drs. Waid-Ebbs and Rose coauthored a paper reporting on a smartphone application for measuring community participation of Veterans with traumatic brain injury (link to abstract at PubMed). This work is important because community participation is one aspect of recovery from conditions like traumatic brain injury, but in order to determine if rehabilitation is effective, there must be a way to measure whether a Veteran is actually improving.  Also, Dr. Waid-Ebbs has coauthored two new publications on this same issue of community participation, one in Archives of Physical Medicine and Rehabilitation and one that is in press in the Journal of Health and Social Work. (October 2021)

Matthew A. Schiefer, PhD Matthew A. Schiefer, PhD  <>  Dr. Schiefer was one of four members of a team called KnowMore that won the Grand Prize in a codeathon hosted by SPARC (Stimulating Peripheral Activity to Relieve Conditions), a program funded by the National Institutes of Health.

BRRC logo with years of funding embedded in it BRRC Renewal!   <>  The BRRC Center grant has been renewed and has a new leadership team: Russell M. Bauer, PhD, will serve as Director and Prodip Bose, MD, PhD, will serve as Associate Director. William J. Triggs, MD, continues as the Medical Director (link to BRRC Investigators and Staff page). With this renewal, the BRRC achieves 25 years of continuous funding (5 funding cycles). In the review of the center grant application, the BRRC was cited for several strengths, including “A broad and diverse group of accomplished investigators with a multidimensional funding portfolio" and “Very high relevance of the patient populations being studied to Veteran’s health and rehabilitation.” Thus, the BRRC forges ahead creating new neural pathways to recovery of functions impaired by neurological injury or disease. (May 2019)

Dana Otzel, PhD Dana Otzel, PhD  <>  Dr. Otzel, a junior BRRC investigator who just completed an RR&D Career Development 1 Award, is a rising star:  She has accomplished a feat that even some long-experienced investigators have never accomplished:  Having three substantial journal articles published within 6 months. Further, she has authored or coauthored 16 publications in the past 4 years. She is now in the process of submitting a Career Development 2 Award. Her program of research focuses on preserving muscle function and mobility after spinal cord injury (SCI), which address an important obstacle to restoring function: neuromuscular impairment and muscle loss. A list of Dr. Otzel's publications is available at this link to PubMed. (February 2019)

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 her study in which two ways of determining level of participation in Veterans with mild traumatic brain injury are compared: 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.  (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, 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 detect 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.
