“…Altered proprioception in PD is marked by elevated thresholds for detecting and discriminating limb and joint movement and position (Fiorio et al, 2007; Klockgether, Borutta, Rapp, Spieker, & Dichgans, 1995; Konczak, Krawczewski, Tuite, & Maschke, 2007; Maschke, Gomez, Tuite, & Konczak, 2003; Zia, Cody, & O’Boyle, 2002) and proprioception (of the neck) has been shown to influence self‐motion perception (Pettorossi & Schieppati, 2014). Also, discrimination of passive whole‐body translations while standing (and blindfolded) is impaired in PD (Bong, McKay, Factor, & Ting, 2020). Thus, abnormal proprioception in PD might affect self‐motion perception.…”
