“…Unsupervised data capture requires extended battery life (Najafi, 2011), methods for limiting sensor placement error (Vanegas and Stirling, 2015), and analytic methods for extracting gait parameters from IMU data. A review of the literature shows a fivesensor system attached to shanks, thighs, and sacrum can provide sufficient information for estimation of center of mass (Westerdijk et al, 2012), spatial gait parameters (Aminian et al, 2002;Li et al, 2009;Sijobert et al, 2015), and joint angle dynamics (Seel et al, 2014), as well as temporal gait parameters (Aminian et al, 2002).…”
