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

Figure 3

Comparison between gait fluctuation (top) and subjective fluctuation (bottom). Examples of patients who subjectively felt no motor fluctuation. Top: serial changes in gait cadence and acceleration during daily activities. 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, red dotted line: mean acceleration − 2SD of normal subjects. The determined gait off is indicated by black rectangle below the top figure. The lack of awareness of motor fluctuation was in agreement with the lack of recorded changes in gait fluctuation in (a), where the two sets of data were in disagreement in (b).
