Research Portfolio
Dr. Cash's projects span three connected themes: brain-body interactions in recovery, neuroplasticity and neuromodulation, and behavioral outcomes research.
Brain-body recovery
Projects in this area examine how brain health, autonomic function, obesity, and mobility interact during stroke recovery.
NIH-funded work examining how obesity may limit brain health and influence recovery after stroke.
Research exploring associations between central autonomic network integrity and mobility performance after stroke.
Neuromodulation
Projects in this area use neuromodulation to understand lower-extremity sensorimotor plasticity and recovery.
Dissertation work characterizing lower-extremity neurophysiological responses to sensory augmentation in chronic stroke, alongside studies evaluating individualized paired associative stimulation as a tool to assay sensorimotor plasticity in healthy adults and people with chronic stroke.
Work focused on lower-extremity motor threshold assessment, corticomotor excitability, and neuronavigated TMS methods that support individualized neuromodulation research after stroke.
Outcomes research
Projects in this area focus on measurement, function, and clinically meaningful outcomes in rehabilitation.
Development and validation of a balance measure designed to capture ability across the spectrum of functional mobility after stroke and other neurologic diagnoses.
Work comparing observational gait analysis with quantitative methods for individuals with severe post-stroke gait impairment.
Research examining ankle angular velocity, acceleration, and other movement variables as reliable measures related to post-injury clinical outcomes.
