This article describes the effects of a new intensive dysarthria treatment program (Be Clear) on speech intelligibility in adults with dysarthria secondary to stroke and traumatic brain injury.
A small group-repeated measures research design was used to examine the effects of treatment on the speech of 8 participants with nonprogressive dysarthria. Treatment consisted of a 1-hr prepractice session followed by 1-hr therapy sessions, 4 times per week, for 4 weeks (16 sessions). Paired-comparison ratings of speech intelligibility served as the primary outcome measure for the study. Perceptual data, quality of life, and communication partner opinion were obtained at 3 time intervals: (a) prior to treatment, (b) immediately posttreatment, and (c) 1-3 months posttreatment.
Following treatment, group data demonstrated substantial improvements in speech intelligibility as perceived by naive listeners on a paired-comparison rating task. Word intelligibility was clinically significantly improved posttreatment and sentence intelligibility demonstrated statistically significant improvement. Communication partner ratings of speech intelligibility and overall communicative function were statistically significantly improved posttreatment.
The results of this study suggest that this new intensive treatment may have potential as an effective intervention for nonprogressive dysarthria. However, controlled studies are required to establish treatment efficacy.
本文描述了一种新的强化构音障碍治疗方案（清晰表达）对中风和创伤性脑损伤继发构音障碍的成年人言语可懂度的影响。
采用小组重复测量研究设计，以检验治疗对8名非进行性构音障碍参与者言语的影响。治疗包括1小时的预练习环节，随后是每周4次、每次1小时的治疗环节，共持续4周（16次治疗）。言语可懂度的配对比较评分作为该研究的主要结局指标。在3个时间点获取感知数据、生活质量和沟通伙伴意见：（a）治疗前，（b）治疗后即刻，以及（c）治疗后1至3个月。
治疗后，小组数据显示，在配对比较评分任务中，由未受过训练的听众感知的言语可懂度有显著改善。单词可懂度在治疗后有临床显著改善，句子可懂度有统计学显著改善。沟通伙伴对言语可懂度和整体沟通功能的评分在治疗后有统计学显著改善。
本研究结果表明，这种新的强化治疗可能有潜力作为非进行性构音障碍的有效干预措施。然而，需要进行对照研究以确定治疗效果。
