The purpose of this study was to evaluate the long-term (12 months) effects of two forms of speech treatment on the speech and voice deficits that occur in Parkinson's disease. Thirty-five patients with idiopathic Parkinson's disease were assigned to one of two speech treatment groups: voice and respiration (The Lee Silverman Voice Treatment [LSVT]) or placebo (respiration) treatment. Vocal intensity data from before, immediately after, and at 6 and 12 months after speech treatment revealed statistically significant differences between the treatment groups. Only subjects in the LSVT group improved or maintained vocal intensity above pretreatment levels by 12 months after treatment. The placebo group had statistically significant deterioration of vocal intensity levels from before to 12 months after treatment during conversational monologue. The LSVT group did not deteriorate to levels below pretreatment in vocal intensity over the 12-month period. This study is the first to document the short-and long-term effects of intensive speech treatment (LSVT), which focuses on the voice, for patients with Parkinson's disease compared with a placebo speech treatment group.
本研究的目的是评估两种言语治疗形式对帕金森病中出现的言语和嗓音缺陷的长期（12个月）影响。35例特发性帕金森病患者被分配到两个言语治疗组之一：嗓音与呼吸训练（李·西尔弗曼嗓音治疗法[LSVT]）或安慰剂（呼吸）治疗组。言语治疗前、治疗后即刻、治疗后6个月和12个月的嗓音强度数据显示，治疗组之间存在统计学上的显著差异。只有LSVT组的受试者在治疗后12个月时嗓音强度有所改善或维持在治疗前水平以上。安慰剂组在对话独白中，从治疗前到治疗后12个月，嗓音强度水平出现了统计学上的显著恶化。在12个月期间，LSVT组的嗓音强度没有恶化到治疗前水平以下。与安慰剂言语治疗组相比，本研究首次记录了针对帕金森病患者的强化言语治疗（LSVT）的短期和长期效果，该治疗聚焦于嗓音。
