How Far Do the Complaints of Patients with Parkinson’s Disease Reflect Motor Fluctuation? Quantitative Analysis Using a Portable Gait Rhythmogram

Figure 1

Serial changes in gait cadence and acceleration during daily activities. Examples of patients who showed fluctuation in the cadence. Left ordinate: the cadence (black continuous line and symbols), right ordinate: acceleration (red continuous line and symbols), abscissa: time, black dotted line: mean cadence ± 1SD of normal subjects, and red dotted line: mean acceleration − 2SD of normal subjects. The patients in (a), (b), and (c) showed synchronized fluctuations in cadence and acceleration, whereas patient in (d) showed desynchronization.
