Background: Motor symptoms in Parkinson's disease (PD) are typically asymmetrical. Early stage of PD is characterised with a predominantly unilateral appearance of tremor, rigidity and bradykinesia, with or without axial involvement. Also, studies have demonstrated gait asymmetry in de novo drug naive PD patients. Aim of this study was to investigate gait pattern, gait symmetry and gait variability in early phases of PD. Methods: The gait was measured in 40 de novo, drug naive PD patients and 43 healthy control subjects (HC) while performing a simple walking task. Calculated parameters were cycle time (CT), stride length (SL) and swing time (ST), and their coefficients of variation (CV). Results: Considering gait parameters, PD patients and HC differed in terms of all parameters, except for the CV of CT. Analysis of gait symmetry, comparison between the gait patterns of the left and the right leg in PD patients revealed no difference for any of the assessed parameters. The majority of the gait parameters did not differ between left and right legs of HC. Conclusions: It can be concluded that even gait was already altered in de novo drug naive PD patients, gait symmetry remained preserved. The SL was the most prominent parameter of altered gait in initial stages of PD patients, while the ST heralded postural asymmetry.
