Rhythmic performance in hypokinetic dysarthria: Relationship between reading, spontaneous speech and diadochokinetic tasks

- We investigated speech rhythm in people with Parkinson's Disease (PwPD) and controls.
- Even mildly affected PwPD differed from controls in their rhythmic performance.
- PwPD showed less difference between reading and spontaneous speech.
- Spontaneous speech highlighted more differences between speakers than reading.
- DDK performance did not relate to rhythmic behaviour in connected speech.
