Subjective Vertical Position Allows Prediction of Postural Deterioration in Patients with Parkinson’s Disease

<div>Regression lines showing the relationships between the 1-year FFT angle and (a) baseline SV angle, (b) baseline FFT angle, (c) baseline LED, and (d) baseline UPDRS III score (D). SV, subjective vertical position; FFT, forward flexion of trunk; LED, levodopa-equivalent dose; UPDRS, Unified Parkinson’s Disease Rating Scale.</div>
