From: Telemonitoring Parkinson’s disease using machine learning by combining tremor and voice analysis
UPDRS | Tremor | Speech |
|---|---|---|
0 | Absent | No problem |
1 | Slight and infrequently present | Loss of modulation yet understandable |
2 | Mild and persistent | Loss of modulation with unclear words |
3 | Moderate and present most of the time | Speech is poorly understood |
4 | Marked and present most of the time | Most speech is unintelligible |
