Sudorometry of the finger was carried out using the ventilated capsule method, the aim being to use the level of relative humidity within the sudorometer as an indirect measure of the sudomotor drive. Subjects inserted a finger through a diaphragm of a finger-shaped, temperature-controlled chamber which also contained the humidity sensor. Manoeuvres known to alter the sudomotor drive produced changes in chamber humidity. The relative humidity within the sudorometer became constant after local anaesthesia of the digital nerves and after upper limb sympathectomy, suggesting that fluctuations in the sudorometer output were dependent upon an intact autonomic nervous system. In an environment in which temperature was controlled and arousal effects from the process of measurement were minimised, chamber humidity always increased during a Stroop test, providing a rapid means of indirectly assessing sudomotor drive mechanisms.
采用通风胶囊法对手指进行汗液测量，目的是将汗液计内的相对湿度水平用作对发汗运动驱动的间接测量指标。受试者将手指穿过一个指状、温度可控的腔室的隔膜，该腔室还装有湿度传感器。已知会改变发汗运动驱动的操作会使腔室湿度发生变化。在对指神经进行局部麻醉后以及上肢交感神经切除术后，汗液计内的相对湿度变得恒定，这表明汗液计输出的波动取决于完整的自主神经系统。在温度得到控制且测量过程中的唤醒效应降至最低的环境中，在斯特鲁普测试期间腔室湿度总是会增加，这提供了一种间接评估发汗运动驱动机制的快速方法。
