slide Disability and Rehabilitation Data Resources: Tools for identifying and accessing survey and administrative data

Secondary datasets are valuable resources for testing hypotheses and generating meaningful statistics related to disability and rehabilitation. We will demonstrate two online resources designed to help researchers learn about:

  • Datasets related to disability and rehabilitation
  • Topics covered by different datasets
  • How to access the datasets
  • Tools to explore and analyze the data
  • Additional dataset resources and how you can share your own data

Rehabilitation Dataset Directory is a browse-able/searchable database providing an overview, description, sample and other pertinent information for over 50 datasets.

ADDEP is a data repository that acquires, preserves, and disseminates research data on disability and rehabilitation providing researchers an interactive space to explore and analyze secondary data.

Big Data for Rehabilitation: Promises, Pitfalls and Future Potential


Organized by Sook-Lei Liew, PhD, OTR/L & Steven Cramer, MD

A persistent challenge in rehabilitation research is the vast heterogeneity within clinical populations. This inter-individual variability makes it difficult to establish significance and reliably replicate findings of rehabilitation studies across smaller sample sizes. Large, diverse datasets (aka “big data”; e.g., n>1000) have the potential to drive rehabilitation research forward by providing the greater statistical power needed for robustly evaluating clinical hypotheses and validating findings from smaller studies. However, collecting, organizing, and analyzing such large amounts of data comes with a number of limitations and considerations. Here we present current applications of ‘big data’ approaches for rehabilitation research across both retrospective and prospective collections of behavioral, neuroimaging, and clinical outcomes data. In each talk, we provide a balanced approach to this topic, highlighting both the potential of ‘big data’ approaches for driving the rehabilitation field forward, as well as the challenges associated with properly implementing, analyzing and interpreting the results. In doing so, we aim to educate attendees about current methodologies and available tools for conducting big data analyses in rehabilitation. We also hope to provide a tempered, realistic view of the limitations of these approaches and ways to complement this approach with experimental approaches. While several of the applications presented here focus on stroke rehabilitation, we emphasize general methodologies and applications that can be related to many rehabilitation populations. Attendees will not only gain big picture insights into how large datasets can be used to further rehabilitation research, but they will also learn practical knowledge regarding what types of information are contained in various databases, how to access or contribute to them, and how to use these resources for their own questions and purposes.

Webinar: Secondary Datasets in Disability and Health: Tools for Researchers Using US Datasets

National survey and administrative datasets continue to be a rich resource for generating national-level statistics for people with disabilities in the United States. Heterogeneous definitions of identifying individuals with disabilities as well as the varying sampling framework limit the use of secondary datasets.
