Abstract
Background: Parkinson's disease (PD) differs from atypical parkinsonism in many clinical aspects. Principally, posture and gait are distinct features in the early stages of the disease; thus, these differences can be helpful in differential diagnosis. Methods: We analyzed videos of patients with PD or atypical parkinsonism. A total of 76 patients with early PD (n= 56) or atypical parkinsonism (n= 20) were included. Items related to posture and gait were classified into three categories (standing, gait and associated symptoms) and each sub-item was analyzed. Results: Asymmetric arm-swing (p= 0.004) and accompanying tremor (p= 0.016) were significant indicators of early-stage PD. Staggering gait (p= 0.007) and en-bloc turning (p= 0.026) were more common in atypical parkinsonism. Characteristics with a high odds-ratio for atypical parkinsonism were en-bloc turning (β= 8.475, p= 0.032) and normal arm-swing (β= 14.6084, p= 0.036). Conclusions: Visual inspection of gait and posture provides reliable clues in the differential diagnosis of parkinsonism.

Bibliographical note
Funding Information:Fifty-six PD patients and 20 AP patients were included in this study. All patients were clinically diagnosed with PD or AP at Korea University Guro Hospital. Motor scores, including gait and posture, had been previously recorded with a camcorder. We included patients who were within five years of initial symptom presentation, had a Hoeh and Yahr (H&Y) stage < 3, and were able to stand and walk without assistance. Clinical diagnosis was based on criteria set by the National Institute of Neurological Disorders and Stroke and the Society for Progressive Supranuclear Palsy (NINDS–SPSP) for progressive supranuclear palsy (PSP), the Multiple Systemic Atrophy (MSA) Consensus criteria for MSA, and the United Kingdom PD Society Brain Bank criteria for PD [2–4] . The study protocol was approved by the relevant institutional review board and all subjects provided written informed consent. 2.2
