A non-invasive way to obtain objective measurements of swallowing frequency and thus indirectly, drooling was required as part of the study 'Drooling in Parkinson's disease: objective measurement and response to therapy'. A hard disk, digital recorder was developed, for use on a laptop computer, which was capable of collecting large quantities of swallowing data from an anticipated 40 patients and 10 controls. An electric microphone was taped to the subjects' larynx for recording the swallow sounds when drinking 150 ml of water and at rest for 30 minutes. The software provides an accurate visual display of the audio-signal allowing the researcher easy access to any segment of the recording and to mark and extract the swallow events, so that swallow frequency may be efficiently and accurately ascertained. Preliminary results are presented.
作为“帕金森病流涎：客观测量与治疗反应”研究的一部分，需要一种非侵入性方法来获取吞咽频率的客观测量值，从而间接测量流涎情况。为此开发了一种硬盘数字录音机，可在笔记本电脑上使用，能够从预期的40名患者和10名对照者那里收集大量吞咽数据。将一个电动麦克风贴在受试者的喉部，用于记录受试者饮用150毫升水时以及静息30分钟期间的吞咽声音。该软件能对音频信号进行精确的视觉显示，使研究人员能够轻松访问录音的任何片段，并标记和提取吞咽事件，从而可以高效、准确地确定吞咽频率。文中给出了初步结果。
