Finger Tapping Clinimetric Score Prediction in Parkinson's Disease Using Low-Cost Accelerometers

Figure 2

𝑧-axis raw signal for an SMD consensus score of 0 obtained from a healthy volunteer performing 10 FT movements. The bullets topped by numbers represent the beginning of a new tapping movement, that is, when the index taps the thumb. The peak in the midst of each movement depicts the finger opening phase.
