Development And Validation Of Wireless Sensors For Applications To Human Head Angular And Mechanical Motions, Karthick Natesan
USF Tampa Graduate Theses and Dissertations
In this project, we programmed a 9 degree of freedom Razor sensor, which incorporates an accelerometer and gyroscope to measure the head linear and angular motions produced by activities of daily living (ADL). The majority of studies concentrate on linear accelerations, so the purpose of this study is to determine the importance of both linear and angular components of acceleration in everyday activities and find interlinked relation between them. The sensor was validated using another calibrated and validated system. The general size and wireless nature make this sensor very suitable for use with human subjects. After obtaining informed consent, we …

Brain Connectivity After Concussion, Armin Iraji

Mild traumatic brain injury (mTBI) accounts for over one million emergency visits in the United States each year. While most mTBI patients have normal findings in clinical neuroimaging, alterations in brain structure and functional connectivity have frequently been reported. In this study, we investigated the large-scale brain structural and functional connectivity using diffusion MRI and resting-state fMRI data. Data from 40 mTBI patients was acquired at the acute stage (within 24 hrs after injury). 35 patients returned for data acquisition at a follow-up (4-6 weeks after injury). Data was also collected from a cohort of 58 healthy subjects, 36 of …
