How Far Do the Complaints of Patients with Parkinson’s Disease Reflect Motor Fluctuation? Quantitative Analysis Using a Portable Gait Rhythmogram
Figure 4
Comparison between gait fluctuation (top) and subjective fluctuation (bottom). Examples of patients who reported motor fluctuations. 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. Awareness of motor fluctuation was in agreement with the recorded changes in gait fluctuation in (a) and (b), but not in (c) and (d).
