|Purpose Like Parkinson's disease (PD), gait disturbance is a major problem in progressive supranuclear palsy (PSP). Despite limited studies investigating the gait characteristics, we hypothesize that they differ from PD owing to the involvement of different brain lesions. Hence, this study aims to investigate the gait characteristics in patients with PSP by comparing with healthy older adults and patients with PD. Methods We identified 27 PSP patients, 25 PD patients, and 25 neurologically healthy older persons. Using a device that detected the distribution of foot pressure during walking, we analyzed gait variables and measured the walking speed (cm/s), cadence (steps/min), step length (cm), step width (cm), foot angle (degrees), and gait cycle time (s). Additionally, we calculated the coefficient of variation (CV, %) on walking speed and cadence and analyzed the gait characteristics by the PSP subtypes. Results In PSP and PD, the walking speed was slower and the step length was shorter than healthy controls. The CV of cadence in PSP was higher than healthy controls and PD. In PSP, the step width and foot angle were higher than healthy controls and PD. The gait cycle time was longer in PSP and PD than healthy controls. PSP with progressive freezing gait tended to display a faster walking speed. Furthermore, PSP with parkinsonism-resembling idiopathic PD tended to exhibit the larger step width and foot angle compared with PSP-Richardsons syndrome. Conclusion This study suggests that the gait of PSP was unstable with parkinsonism and wide-based, which might be similar to combining features of PD and cerebellar disorders.
