To analyze the frequency of speech disruptions across different speech tasks, comparing the performance of individuals with Parkinson's Disease (PD) and DS.
Participants were 20 people with PD, 20 people with DS and 40 fluent individuals. Speech samples were recorded during monologue speech, choral and solo oral reading. Transcriptions of 200 fluent syllables were performed to identify stuttering-like disfluencies (SLDs) and other disfluencies (ODs).
People with PD presented significantly less speech disruptions when compared to people with DS, but significantly more speech disruptions than the control group. Stuttering-like disfluencies ocurred more frequently during monologue speech and solo oral reading for both PD and DS, whereas the control group did not present difference between these tasks.
The stuttering pattern presented by people with PD is different from what is usually described as being neurogenic stuttering.
分析不同言语任务中言语中断的频率，比较帕金森病（PD）和进行性核上性麻痹（DS）患者的表现。
参与者包括 20 名 PD 患者、20 名 DS 患者和 40 名流利个体。在独白、合唱和独唱朗读期间记录言语样本。对 200 个流畅音节的转录进行分析，以识别类口吃性不流畅（SLD）和其他不流畅（OD）。
与 DS 患者相比，PD 患者的言语中断明显减少，但与对照组相比，言语中断明显更多。PD 和 DS 患者在独白和独唱朗读时更频繁地出现类口吃性不流畅，而对照组在这些任务之间没有差异。
PD 患者的口吃模式与通常描述的神经源性口吃不同。
