This Spotlight continues to focus on the NCMRR as the Center commemorates its 20th anniversary.
The need for the Center and its research programs was clear in 1991, when it was established, and has only grown in the last two decades. For instance, the Centers for Disease Control and Prevention estimates that approximately:
A previous Spotlight explained the Center's establishment and early years; here we highlight the NCMRR's wide-ranging research programs and resulting advances in the field of medical rehabilitation. To learn more, select a link below:
Much of the Center's initial activities aimed to further build medical rehabilitation as an innovative scientific field and to expand infrastructure for rehabilitation research. Later, the NCMRR expanded its activities to support basic and patient-oriented research within seven priority areas. With these areas defined and a Research Plan (PDF - 222 KB) in place, the NCMRR began building its own infrastructure by creating several distinct but interrelated research programs to address a broad portfolio of research on rehabilitation of physical disabilities across the lifespan. Although each program has its own specific focus area(s), many of the NCMRR's projects are multidisciplinary and cross multiple programs.
The BSRT Program includes two broad rehabilitation research areas—behavioral research and rehabilitative technology research. The behavioral portion of the Program's portfolio is meant to address not only the unique behavioral and social challenges faced by those with disabilities, but also the direct effects, such as the cognitive symptoms related to stroke, of chronic and disabling conditions and the effects of behavioral and social influences on treatment outcomes. Some research topics within this area include, but are not limited to, studies of: how those with disabilities and their families shape social encounters to create desired outcomes; the effects of family-centered therapy versus individual-centered therapy; alternative methods for reducing pain among those going through rehabilitation; and understanding the behavioral and social risk factors associated with the onset and course of illness and health.
The rehabilitative technology aspect of the Program's portfolio focuses on applied research. Projects within this Program area aim to enhance human-environment interactions by improving or restoring a person's ability to function in his or her environment. Such activities include not only cutting-edge innovations, but also approaches that can standardize measurement and outcomes reporting, which is critical for comparing interventions. Some research topics in this area include, but are not limited to, studies of: robotics for use in rehabilitation therapy; development of instrument systems to measure symptoms and rehabilitation progress; body-computer interface technologies; and improvements to wheelchairs.

The BSCD Programsupports basic research on substrate responses to injury and on strategies to promote regeneration, recovery, plasticity, adaptation, and recovery. This type of research could include studies of: activity-mediated processes, such as treadmill training and constrained-use therapy for movement problems from stroke and other conditions; muscle and bone function, such as contractures and sarcopenia that result from chronic disuse of muscles; secondary conditions, such as pain, depression, and cardiovascular dysfunction; and genomic influences, meaning that slight differences in genetic code could influence response to injury and interventions.
Training and career development have been a top priority since the inception of NCMRR. The BSCD Program supports individual fellowships and national career development networks for rehabilitation clinicians. To further support rehabilitation researchers and attract researchers from allied fields, the Program hosts workshops to review NIH funding opportunities, peer review, grantsmanship, and networking. In addition, the Program works with other NIH Institutes to sponsor the Medical Rehabilitation Research Infrastructure Network to improve research capacity and information transfer.

The PCCR Program focuses on research topics related to longer term issues faced by children and young adults with disabling, complex, and special health care needs. Most of these patients have many years of life and development ahead of them and have either survived life-threatening critical illness or injury, or were born with disabling conditions. Program research addresses (but is not limited to): examining issues faced by children who have survived trauma or injury of diverse causes (including birth trauma); understanding critical illness or injury treatment and recovery; mapping the course of critical illness or disease, such as septic shock or organ failure, and patients' recovery from these conditions. The Program's research also addresses developmental and genetic disorders and chronic conditions that cause disabilities, such as cerebral palsy, a leading cause of disability in children.
A primary activity of the PCCR Program is support for the Collaborative Pediatric Critical Care Research Network (CPCCRN), a network of translational and clinical centers dedicated to advancing PCCR medicine by conducting clinical trials and other meaningful studies in pediatric and young adult populations. The Program also supports research on pediatric-appropriate instruments, technologies, methods/approaches, and other issues related to the care of children with special health care needs. Some examples of these types of efforts include the use of less-invasive respiratory support, technologically advanced monitoring of vital functions, and the translation of adult critical care science into meaningful strategies for infants and children.

The SMAD Programportfolio addresses multiple research areas, including spinal cord injury (SCI), musculoskeletal disorders, and the development, testing, and evaluation of assistive devices. Within the context of SCI, the Program supports translational and clinical research studies focused on rehabilitation of conditions associated with chronic complete and incomplete SCI across the lifespan. Some topics include: enhancing spinal cord circuitry; enabling beneficial plasticity; restoring movement; and understanding important SCI secondary conditions, such as pain, pressure ulcers, chronic bladder and bowel dysfunction, and symptoms related to autonomic dysreflexia (a life-threatening spike in blood pressure common in SCI patients). Research for SCI also includes musculoskeletal conditions, such as bone loss and muscle atrophy, and therapeutic interventions, such as exercise, to address symptoms and improve overall fitness and health. Other research addresses impairments in upper and lower limb function and motor control, gait, human motion, posture, and physical fitness and health. This research is important not only for those with musculoskeletal disabilities (with or without paralysis), but also for those with cerebral palsy, multiple sclerosis, spinal bifida, Parkinson's disease, stroke, low back pain, some joint disorders or conditions that result from arthritis and injury, and other conditions.
The SMAD Program also supports research related to assistive devices designed to restore or enhance a person's ability to function in his/her environment. Some examples include: improved seating and wheelchair technologies; tools and modeling approaches to understand, prevent, or detect specific conditions related to physical disabilities; new or improved devices or systems designed to enable accessibility or fitness for persons with physical disabilities; orthoses (orthopedic devices that support, align, prevent, or correct deformities or improve function); mobility monitors; and communication aids. The SMAD Program also has a focus on brain-computer or brain-machine interface technologies that may be clinically designed to improve brain control over functions, such as limb movement, or to control the use of assistive devices to improve function and quality of life. This portion of the SMAD Program portfolio complements the rehabilitative technology portion of the BSRT Program by also supporting the development, application, and evaluation of innovative technologies to improve function and capability.

The TSR Program supports research on two leading causes of acute and chronic disability in the United States. Many people are familiar with TBI from motor and bicycle accidents, falls, and sports injuries; but research now shows that even a concussion, which was once thought of as a minor injury, can have major effects on brain and body function. Although researchers understand significantly more about TBI and its mechanisms that they did when the NCMRR was established, much work remains to improve the outcomes of those affected by TBI. Ongoing studies include: refining clinical guidelines for the treatment of TBI immediately following the injury, and at different time periods after the injury; exploring the capabilities of cognitive therapy for improving outcomes after TBI; measuring impact experiences to determine levels of damage and the best way to detect damage; and understanding the link between TBI and secondary conditions, such as depression. Another project that is in its last year of funding is the NICHD TBI Clinical Trials Network, which relied on multiple centers using the same research protocols and interventions to enroll enough TBI patients to collect rich data and provide answers more quickly than individual centers could alone.
Stroke occurs when a blood clot or a break in a blood vessel interrupts blood flow to the brain; this lack of blood flow causes damage that can affect cognitive and motor abilities. Some of the projects within the TSR Program complement those supported by the SMAD Program, especially those that address issues related to recovering movement and mobility following stroke. Other ongoing areas of research within the stroke portion of the Program include studies of combinations of pharmacological, surgical, and physical therapies to improve stroke outcomes; the effect of compensatory training for unimpaired extremities; and measuring caregiver burden at different times post stroke.

The list below highlights some of the innovative projects and research advances supported by the NCMRR. This list is not meant to be comprehensive, but aims to help explain the breadth of the Center's research portfolio.
In the previous Spotlight, Michael Weinrich, M.D., Director of the NCMRR, shared some of his thoughts about the Center's establishment and early years. In this continued conversation with Dr. Weinrich, he addresses NCMRR-supported research innovations.
Question: What do you view as the top five NCMRR-supported rehabilitation innovations over the last 20 years? Dr. Weinrich: It is difficult to single out individual projects as there has been so much progress along so many different lines. I'd prefer to highlight areas of research and use individual projects as illustrative examples:
Question: What do you anticipate will be the most promising scientific opportunities down the road for the Center? Dr. Weinrich: Promising scientific opportunities are best identified by the individuals working in the field. Some obvious opportunities exist for more effective community translation of rehabilitation interventions using modern telecommunications. Recent advances in robotics, battery and motor design, and signal processing may allow for the development of user-friendly powered assistive devices that will improve functional abilities for individuals in the community. The potential of stem cells and regenerative medicine is vast. We do not yet know how to accomplish effective repair of damage to the nervous system.
Finally, an understanding of function at the cellular and subcellular level can yield astonishing advances. For example, a currently funded NIH project on macular degeneration and retinitis pigmentosa (the most common causes of acquired blindness in the United States) is developing a way to make the retinal ganglion cells that survive light sensitive. This research may be the beginning of an entirely new approach to vision rehabilitation for these individuals.
In addition, the NCMRR is involved in the NICHD-wide Vision process. Many Vision themes, such as Plasticity and Diagnostics and Therapeutics, are integral to the Center's mission and research. The Institute's decisions related to the Vision process will undoubtedly influence future research plans at the NCMRR.
During the last 20 years, the NCMRR has not only solidified medical rehabilitation as a scientifically robust and innovative field, but has also helped to advance understanding and management of various physical disabilities and conditions throughout the lifespan. The NCMRR remains a leader in supporting new discoveries, new technologies, and new approaches that improve the lives of those with physical disabilities and disabling conditions. By continuing to expand its research portfolio and the cadre of rehabilitation researchers and clinicians, the Center's future is both exciting and bright.
