Issi 8,

Your scores on the side-to-side tap test are high for both a PwP and a healthy person. (Note for this test "high" means good, whereas for the UPDRS test "high" means bad.)

The test you did was a stand-alone version that did not store the results. There is also a different version that stores the results and on which statistics are calculated. These show that the test has been taken 770 times, almost all by people diagnosed with Parkinson's. There, the mean for the left-hand is 20.7 and for the right-hand it is 20.4, and with maximum values of 38.4 and 40.6, respectively.

On the other hand, your test score increased slightly after you took your drugs, which hints at a response to the dugs. But this is a single result, so it does not have statistical significance.
