OBJECTIVE:To define the effects of Lee Silverman Voice Treatment (LSVT on swallowing and voice in eight patients with idiopathic Parkinson's disease.

METHODS:Each patient received a modified barium swallow (MBS) in addition to voice recording before and after 1 month of LSVT. Swallowing motility disorders were defined and temporal measures of the swallow were completed from the MBS. Voice evaluation included measures of vocal intensity, fundamental frequency, and the patient's perception of speech change.

RESULTS:before LSVT, the most prevalent swallowing motility disorders were oral phase problems including reduced tongue control and strength. Reduced tongue base retraction resulting in residue in the vallecula was the most common disorder in the pharyngeal stage of the swallow. Oral transit time (OTT) and pharyngeal transit time (PTT) were prolonged. After LSVT, there was an overall 51% reduction in the number of swallowing motility disorders. Some temporal measures of swallowing were also significantly reduced as was the approximate amount of oral residue after 3 ml and 5 ml liquid swallows. Voice changes after LSVT included a significant increase in vocal intensity during sustained vowel phonation as well as during reading.

CONCLUSIONS:LSVT seemingly improved neuromuscular control of the entire upper aerodigestive tract, improving oral tongue and tongue base function during the oral and pharyngeal phases of swallowing as well as improving vocal intensity.

目的 : 定义Lee Silverman语音治疗 (LSVT对8例特发性帕金森氏病患者的吞咽和语音的影响。
方法 : 除了在LSVT前后1个月的语音记录外,每位患者还接受了改良的钡吞咽 (MBS)。定义了吞咽运动障碍,并从MBS中完成了吞咽的时间测量。语音评估包括声音强度,基本频率,以及患者对言语的感知变化。
结果 : 在LSVT之前,最普遍的吞咽运动障碍是口腔阶段的问题,包括减少的舌头控制和力量。减少的舌根回缩导致的山谷中残留是吞咽阶段最常见的疾病。口腔通过时间 (OTT) 和咽通过时间 (PTT) 延长。LSVT后,吞咽运动障碍的数量总体51% 减少。吞咽的一些时间测量也显着减少,3毫升和5毫升液体吞咽后的口腔残留物的大致数量也显着减少。LSVT后的声音变化包括在持续元音发声以及阅读期间发声强度的显着增加。<
结论 :LSVT似乎改善了整个上消化道的神经肌肉控制,改善了吞咽的口腔和咽阶段的口腔舌和舌根功能,并改善了声音强度。
