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

Table 1

MDS-UPDRS instructions for FT task scoring [4] (instruct the patient to tap the index finger on the thumb 10 times as quickly and as big as possible. Rate each side separately, evaluating speed, amplitude, hesitations, halts, and decrementing amplitude).

Score Scoring instructions

0 No problems

1 Any of the following:
(a) the regular rhythm is broken with one or two interruptions or hesitations of the tapping movement;
(b) slight slowing;
(c) the amplitude decrements near the end of the 10 taps.

2 Any of the following:
(a) 3 to 5 interruptions during tapping;
(b) mild slowing;
(c) the amplitude decrements midway in the 10-tap sequence.

3 Any of the following:
(a) more than 5 interruptions during tapping or at least one longer arrest (freeze) in ongoing movement;
(b) moderate slowing;
(c) the amplitude decrements starting after the 1st tap.

4 Cannot or can only barely perform the task because of slowing, interruptions, or decrements.
