Left hand
-
- Evaluating hand:
- left
-
- Quality control: high confidence
- error frame ratio: 0.0
-
- Deep learning model:
- predicted UPDRS: 0
-
- Evaluating indices:
- (TOP) frequency: 4.5 ± 1.1 (Hz)
- (TOP) intensity: 0.099 ± 0.099 (A.U.)
- (TOP) inte-freq: 0.442 ± 0.124 (A.U./s)
- (MIDDLE) peak: 0.51 ± 0.07
(distance/thumb-length) - (BOTTOM) absolute difference of frequency: potentially detect "interrupt" or "hesitate" if the peak is high.
Right hand
-
- Evaluating hand:
- right
-
- Quality control: high confidence
- error frame ratio: 0.013
-
- Deep learning model:
- predicted UPDRS: 2
-
- Evaluating indices:
- (TOP) frequency: 1.7 ± 0.6 (Hz)
- (TOP) intensity: 0.071 ± 0.071 (A.U.)
- (TOP) inte-freq: 0.119 ± 0.05 (A.U./s)
- (MIDDLE) peak: 0.52 ± 0.13
(distance/thumb-length) - (BOTTOM) absolute difference of frequency: potentially detect "interrupt" or "hesitate" if the peak is high.
