walking trials at a self-selected pace were completed by the 14 patients (Fig. 1C). After independent subjective and objective inspections, consensus between the two approaches was reached in 407 trials on whether the trial contained freezing (inter-rater reliability = 90.2%). Among the 407 trials, 114 were freezing trials with an average trial duration of 85.9 s, including 294 freezing events with average event duration of 11.5 s and a total freezing duration of 3384 s, and 293 were non-freezing trials, with an average trial duration of 24.1 s and a total walking duration of 7073 s. All recordings were conducted in the OFF-medication state.
