Visual impairment, known as blindness and low vision, is considered one of the most common disabilities and functional impairments in people that affect people's efficiency (Salomão, Mitsuhiro, & Belfort Jr, 2009). The sense of sight is one of the problems that the World Health Organization is concerned with, because globally about 150 million people suffer from vision problems and 50 million people are blind (Woldeyes & Adamu, 2008). Not having a sense of sight makes a blind person face functional and movement limitations, one of the most important of which is walking (Majlesi & Farahpour, 2015). Gait, the scientific term used to describe the human walking pattern, is simple in execution, but complex in terms of motor control and biomechanics (Beauchet et al., 2017). Objective measures of the temporal and spatial parameters of walking provide the possibility of defining the level of impairment and characterizing walking performance, which can be used as a biological indicator in mobility; The most commonly used temporal parameters of walking include stride time (s), swing phase (%), stance phase (%), dotacular support (%), and cadence (steps/min) (Kahaki, Safarpour, & Daneshmandi, 2023).
