A Wearable Motion Analysis System To Evaluate Gait Deviations, Amanda Lynn Martori
A Wearable Motion Analysis System To Evaluate Gait Deviations, Amanda Lynn Martori
USF Tampa Graduate Theses and Dissertations
A Wearable Motion Analysis System (WMAS) was developed to evaluate gait, particularly parameters that are indicative of mild traumatic brain injury. The WMAS consisted on six Opal IMUs attached on the sternum, waist, left and right thigh and left and right shank. Algorithms were developed to calculate the knee flexion angle, stride length and cadence parameters during slow, normal and fast gait speeds. The WMAS was validated for repeatability using a robotic arm and accuracy using the Vicon motion capture system, the gold standard for gait analysis. The WMAS calculated the gait parameters to within a clinically acceptable range and …
