Erin Snook’s research interests include understanding the antecedents and outcomes of physical activity behavior in populations with neurological diseases, particularly multiple sclerosis (MS), and improving and/or developing new outcome measures to be used in MS and other populations.  During her CRF Scholar year, Dr. Snook will develop a grant which proposes to track the progression of multiple sclerosis using two novel outcome measures that are being developed and tested in her current research. The first outcome measure focuses on the assessment of MS symptoms. The second outcome measure combines GPS and physical activity data to provide a measure of real-world function. Currently available measures of MS symptoms and function have significant limitations. Accurate measurement of MS symptoms and functional outcomes is vital for determining the effectiveness of rehabilitation and treatments and for tracking the progression of MS, thus the development and testing of new symptom and functional outcome measures needs to be a priority for MS research.
