A 36-year-old female with severe spastic dysarthria participated in this study. She received 4 weeks of individual intensive voice-focused treatment. Voice recordings were conducted at three baseline points, immediately posttreatment, and at a 4-month follow-up. The primary outcome variables were selected acoustic measures of vocal function: sound pressure level (SPL), mean fundamental frequency (F0), maximum phonation time (MPT), jitter, shimmer, noise-to-harmonics ratio (NHR), and maximum phonation frequency range (MPFR). Significant pre-to-posttreatment changes (p < .05) were found for most acoustic variables. All acoustic gains, except for MPFR, were maintained at the 4-month follow-up. The significant posttreatment changes in the majority of the acoustic measures analyzed suggest that intensive voice-focused treatment may have the potential to improve vocal function in adults with severe spastic dysarthria secondary to cerebral palsy (CP). Evidence-based treatment options for voice disorders in adults with CP are limited. Results emphasize the need for more studies with this population.

一名患有严重痉挛性构音障碍的36岁女性参加了这项研究。她接受了为期4周的个人强化语音治疗。语音记录在三个基线点进行，即刻后治疗和4个月的随访。选择的主要结果变量是人声功能的声学测量值：声压级（SPL），平均基频（F0），最大发声时间（MPT），抖动，微光，噪声与谐波比（NHR）和最大发声频率范围（MPFR）。治疗前后的重大变化（p对于大多数声学变量，发现<0.05。在4个月的随访中，除MPFR外，所有声学增益均保持不变。在分析的大多数声学测量中，重大的治疗后变化表明，以语音为重点的强化治疗可能具有改善继发于脑瘫（CP）的严重痉挛性构音障碍的成年人的声音功能的潜力。CP成年人语音障碍的循证治疗选择有限。结果强调需要对该人群进行更多的研究。
