Comparison Of Diadochokinetic Rate Measures In Individuals With Post-Stroke Spastic And Unilateral Upper Motor Neuron Dysarthria

De-identified Excel data supporting the findings of this study are available in an open repository. The dataset includes participant-level diadochokinetic (DDK) rate measures (syllables/second) for alternating (/pʌ/, /tʌ/, /kʌ/) and sequential (/pʌtʌkʌ/) tasks, along with basic demographic and clinical grouping variables required to reproduce the reported analyses (healthy vs. dysarthria; SD, right UUMND, left UUMND). To protect participant privacy, the repository does not include raw audio recordings or any direct identifiers; audio files contain personal speech content and are therefore not shared. The repository record provides the permanent link/DOI and file-level metadata needed for reuse.
