Two studies evaluated feedback of total respiratory resistance of the airways (TRR) as a treatment for adults with moderate to severe chronic bronchial asthma. Respiratory function tests and questionnaires were used to select the patients and to assess treatment effects. Study I provided eight biofeedback sessions in four weeks (each session containing four, 3-min training trials) plus three pre-treatment and three post-treatment sessions. Over the eight treatment sessions biofeedback failed to produce any significant improvements, although overall the nine patients showed lower mean initial TRR values at the three post-treatment sessions compared with the three pre-treatment sessions. Patients consistently showed improvement following bronchodilator administration at the end of every session. In study II, biofeedback was provided in one intensive session of 20, 2-min trials. While careful instruction about biofeedback was provided to subjects, and more post-treatment measures were included, no significant improvements were shown following biofeedback, but were shown following bronchodilator administration.
两项研究评估了气道总呼吸阻力（TRR）反馈作为中度至重度慢性支气管哮喘成人患者的一种治疗方法。呼吸功能测试和问卷调查被用于选择患者并评估治疗效果。研究I在四周内提供了八次生物反馈疗程（每次疗程包含四次3分钟的训练试验），外加三次治疗前和三次治疗后疗程。在这八次治疗疗程中，生物反馈未能产生任何显著改善，尽管总体而言，与三次治疗前疗程相比，九名患者在三次治疗后疗程中的初始TRR平均值较低。在每次疗程结束时给予支气管扩张剂后，患者始终显示出改善。在研究II中，通过一次包含20次2分钟试验的强化疗程提供生物反馈。虽然向受试者提供了关于生物反馈的详细指导，并且纳入了更多治疗后测量指标，但生物反馈后未显示出显著改善，而支气管扩张剂给药后则显示出改善。
