Feasibility of Using Dynamic Time Warping to Measure Motor States in Parkinson’s Disease

Table 2

Distance measures for one patient. R is the right foot and L is the left foot. The values correspond to the calculated distances between test occasions. Acc is acceleration. Gyr is gyroscope. is magnitude acceleration. is magnitude gyroscope. Acc_Y is acceleration in the -axis.
