“…Axial rigidity, increased postural tone, en bloc turning, FOG, and loss of intersegmental exibility may be evident during gait in PD, particularly in walking and turning gait [39][40][41][42]. Speci cally, individuals with early-stage PD experience a reduced range of motion at the hip joint [43], asymmetric tremors, decreased coordination [44], and reduced postural stability control [45] during gait, which exacerbate with progression to moderate PD [46].…”
