**6.4 Results**

**Table 4** shows a comparison of arm swing variables obtained for each limb with the eMotion. This shows that arm swing magnitude (left p = 0.002, right p = 0.006) and arm swing speed (left p = 0.002, right p = 0.004) were significantly reduced in the PD group for both limbs. The control group shows a lowest arm swing asymmetry than the patient group (p < 0.001). Based on the side, the variables that show significant differences for the left side were arm swing magnitude, speed, and ASA and for the right side were arm swing magnitude, speed, and ASA. Also, the most affected side determined with Kinect and the one with the highest score of the pondered items of the MDS-UPDRS-III were compared. These comparisons suggest that our device is to recognize the most affected side in the 80% of cases. Due to the limited sample size, differences in the symmetrical group were not evaluated.
