A sample of 126 individuals (74 females and 52 males) was recruited from 2016 to 2021 to participate in this study, and consisted of 63 individuals with PD and 63 age-, body mass-, and body height-matched neurologically healthy individuals. The PD participants were recruited from the Ativa Parkinson community project at São Paulo State University (Unesp) - Campus Bauru, and the neurologically elders from a university database. The protocol of data collection was performed in a single session, and included an interviewed to collect clinical data, medication and disease diagnosis. For the gait assessment, participants walked three times on an unobstructed path (8.5 x 1.5m) at a self-selected pace while wearing markers for three-dimensional gait collection in according to full-body plug-in-gait pattern (Vicon, Nexus). The gait parameters were acquired using 10 Vicon Motion Systems® cameras (100 Hz). The following spatial-temporal gait parameters were calculated: step/stride length, width, duration and velocity, single and double support time and cadence.
