Kinematic assessment of overground gait was performed by the Qualisys Motion Capture Systems (Qualisys Medical AB, 411 13 Gothenburg, Sweden), which records the spatiotemporal variables of gait, as well as angular variations of hip, knee and ankle joints. This system is composed of eight cameras that emit and capture infrared light. The light is reflected by spherical passive markers positioned on bony prominences and standard body segments, in order to capture lower limb data. The cameras are connected to a computer, where the images collected are stored. Data captured in two-dimensional imaging are processed by Qualisys Track Manager 2.6 acquisition software, which recognizes marker positioning and, based on the combination of images from at least two cameras connected in series, enables the generation of three-dimensional coordinates of movement. To that end, data are transported by 3D visual software (C-Motion, Rockville, MD, USA), version Basic/RT 3.99.25.8), which allows the reconstruction and three-dimensional analysis of the body segments marked, thereby recording the movements executed during gait.
