OBJECTIVE: This study aimed to characterize the posturographic features of elderly patients newly diagnosed with early-stage Parkinson's disease (PD) who initially presented with dizziness.
METHODS: Over a three-year period, 1,840 patients visited a dizziness-specialized otolaryngology clinic. Among them, four were newly diagnosed with early-stage PD. Posturographic data of these patients were analyzed.
RESULTS: Common posturographic characteristics were observed, including elevated locus length per unit area (L/A), calculated by dividing the total locus length by the sway area, and increased sway frequencies in the 5-8 Hz range as seen in the power spectral analysis.
CONCLUSION: In line with previous findings, elevated L/A values and higher sway frequencies may be useful early indicators of PD.
