Abstract
Project Summary Abstract Between and million people each year suffer a mild TBI in the US alone Reliable diagnosis and prompt treatments are vital to managing the often serious short and long term sequelae resulting from mild TBI However a reliable objective and accurate method for mild TBI diagnosis outside of a hospital setting and in particular for determining RTP readiness has eluded the clinical community Current diagnosis and RTP assessments are based on patient symptoms neurocognitive evaluations and or physical performance testing Use of symptom scales are problematic for several reasons including subjectivity and reliability Neurocognitive evaluations and physical tests such as balance tests although less subjective require pre injury baseline testing of subjects due to inherently large subject to subject variations in evaluation performances Due to these reasons current mild TBI diagnostic methods have limited applications and are not suitable for a significant majority of patients who suffer mild TBI This project is aimed at developing an objective diagnosis of mild traumatic brain injury mild TBI based on physiologic changes in a patient after injury and providing a platform capable of RTP guidance The method is based on quantification of well known physiologic changes after a concussion i e the impairment of autonomic function and altered cerebral blood flow CBF as measured with transcranial Doppler TCD The novelty of the proposed approach is the use of a recently developed analytical machine learning framework for the analysis of the CBF velocity CBFV waveforms In contrast to previous methods used before the proposed approach utilizes the entire shape of the complex CBFV waveform thus obtaining subtle changes in blood flow that are lost in other analysis methods Additionally comprehensive verification between our platform and MRI will be performed following injury resulting in the first scientific experiments of this kind The ultimate goal of this Phase II SBIR is to commercialize an objective and accurate software algorithm for reliable diagnosis and management of sports concussions which does not currently exist The outcome will be a software suite integrated into existing TCD and will be marketed to emergency departments neurology clinics and other healthcare providers involved in mild TBI diagnosis and RTP management Project Narrative Traumatic brain injury TBI is a serious public health problem in the United States contributing to a substantial number of deaths and cases of permanent disability Mild TBI concussions account for over of all TBIs sustained and a major problem is the high rate of mis diagnosis due to lack of objective measures and delayed onset of symptoms This project aims to develop the first objective concussion evaluation method using a novel analysis platform that can obtain subtle physiologic changes in cerebral hemodynamics Successful completion of this project will result in a portable diagnostic device suitable for use in many scenarios where concussion diagnosis is inaccurate or unavailable today
