Abstract Details

2013, Master of Sciences, Case Western Reserve University, Biomedical Engineering.
This project developed a paradigm capable of measuring brain activity using fMRI before and after rehabilitation for hand paralysis. The paradigm is based on a hand motor control task, where subjects alternate between periods of rest and active states. During the active phase, subjects extend their fingers against an MRI-compatible force transducer, which was developed and tested in this project. This project verified that the finger force device was MRI compatible, provided accurate force measurements with minimal baseline drift, and operated with sufficiently small time delay. The sensor was then compared in an able-bodied subject to a similar position-tracking task from the literature. Force tracking elicited a greater spatial extent of neural activation, and also allowed the user to more accurately follow the visual track. This is the first hand extensor force sensor developed for this application, and can be used longitudinally in a wide range of rehabilitation interventions.
