“…While there are some low cost devices for quantifying spatiotemporal parameters of gait (e.g., cadence, step length and symmetry, step and stride duration, etc.) (Bergamini et al, 2013; Salarian et al, 2010; Spain et al, 2012), there are not many low cost instrumentations for kinematic evaluation (Bonnet et al, 2012; Picerno et al, 2008). Further, these devices typically don’t provide real-time data, which may be of particular interest to clinicians due to its application for gait training in virtual environment.…”
