One in 5 Americans experiences disability that affects daily function because of impairments in mobility, impairments in cognitive function, sensory impairment, or communication impairment. The need for rehabilitation strategies to optimize function and reduce disability is a clear priority for research to address this public health challenge. The National Institutes of Health (NIH) recently published a Research Plan on Rehabilitation that provides a set of priorities to guide the field over the next 5 years (Eunice Kennedy Shriver National Institute of Child Health and Human Development [NICHD] & NIH Medical Rehabilitation Coordinating Committee [MRCC], 2016). The plan was developed with input from multiple institutes and centers within the NIH, the National Advisory Board for Medical Rehabilitation Research, and the public. This article provides an verview of the need for this research plan, an outline of its development, and a listing of six priority areas for research. The NIH is committed to working with all stakeholder communities engaged in rehabilitation research to track progress made on these priorities and to work to advance the science of medical rehabilitation.
