The objective of the study was to train asthma patients to improve their ability to discriminate added resistive loads.
Training consisted of a task in which patients judged the relative difficulty of breathing through two circuits. Difficulty of breathing through the circuits was varied by addition of resistive loads. We assigned 45 patients randomly to one of three conditions: a feedback plus fading condition, a feedback condition, and a control condition.
Feedback of accuracy of judgments coupled with fading resulted in reduction of difference threshold. Neither feedback alone nor a control condition in which patients were given experience in making judgments without feedback resulted in threshold change.
Perception training with added resistive loads may help patients to detect an increase in air flow obstruction due to asthma before it becomes severe.
本研究的目的是训练哮喘患者提高辨别附加阻力负荷的能力。
训练包括一项任务，即患者判断通过两个回路呼吸的相对难度。通过添加阻力负荷来改变通过回路呼吸的难度。我们将45名患者随机分配到三种条件之一：反馈加渐隐条件、反馈条件和对照条件。
判断准确性的反馈与渐隐相结合导致差异阈值降低。单独的反馈或患者在无反馈情况下进行判断的对照条件均未导致阈值变化。
附加阻力负荷的感知训练可能有助于患者在气流阻塞因哮喘变得严重之前检测到其增加。
