The establishment of pulmonary rehabilitation program using the Locomotor Respiratory Coupling System.

众所周知，呼吸节律导致有节奏的运动，这种现象被称为运动呼吸耦合(LRC)。我们调查和报道了健康受试者的LRC，并注意到LRC现象提高了运动时的通风效率。另一项研究表明，在中等负荷的情况下，LRC可以降低自行车的氧耗量(VO2)。因此，我们研究了LRC现象是否可以应用于慢性阻塞性肺疾病(COPD)患者的运动训练。我们开发了新的测功机系统软件(Strong Ergo 240BK-ERG003：SE，三菱电机工程，日本)，它促进了LRC使用视觉和声音信号。本研究旨在探讨该系统对慢性阻塞性肺疾病患者肺功能康复的影响。1)与脚踏…同步的PC显示屏上会出现语音和文字信号，如“吸气”、“呼出”更大的G角。2)信号总是出现在固定的踏板位置，因为信号的定时由踏板位置控制。因此，每分钟的踏板速度越慢，信号出现的速度就越慢。3)该软件可以创建各种比率(运动/呼吸)，并可选择1：1、3：2、2：1、5：2、3：1、7：2、4：1、4)该软件可以改变运动时的信号设置。我们在踏板运动中测量了佩戴该系统前后的SpO2、RPE(Borg Scale)、HR和运动耐量(最大持续运动持续时间)，并比较了佩戴该系统前后结果指标的差异。运动时使用该系统的RPE和HR均低于不使用该系统的RPE和HR。结论：LRC易化系统可用于慢性阻塞性肺疾病患者的肺康复。较少

It is known that respiratory rhythm entrains to rhythmical movement, a phenomenon called Locomotor Respiratory Coupling (LRC). We investigated and reported on LRC in healthy subjects, and noted that the LRC phenomenon enhances ventilation efficiency during exercise. Another study has shown that LRC decreases oxygen consumption (VO_2) during cycling at a moderate workload. Therefore, we investigated whether LRC phenomenon may be applied to exercise training for patients with Chronic Obstructive Pulmonary Disease (COPD). We developed new ergometer system software (Strength Ergo 240BK-ERG003 : SE, Mitsubishi Electric Engineering, Japan), which facilitates LRC using visual and acoustic signals. The aim of our study was to investigate the effect of this system for pulmonary rehabilitation of patients with COPD.The properties of this new system software are as follow. 1) Voice and word signal such as "breathe in", "breathe out", appear on the PC display which is synchronized with the pedalin … More g angle. 2) The signal always appears at a settled pedaling position, because timing of the signal is controlled by the pedaling position.Therefore, the slower the pedaling rate per min., the slower the signal appearance. 3) This software can create various ratios (locomotion/respiration) and choose from the following : 1 : 1, 3 : 2, 2 : 1, 5 : 2, 3 : 1, 7 : 2, 4 : 1, 4) The software can change the signal setting during exercise.Seven patients with respiratory COPD participated in this study. We measured SpO2, RPE (Borg Scale), HR, and exercise tolerance (maximum duration of continuous exercise) both with and without this system during pedaling exercise, and compared the differences between outcome measures with and without this system.With this system, SpO2 was higher than without this system during exercise. RPE and HR with this system were lower than without this system during exercise. Exercise tolerance (duration) with this system was longer than without.We concluded that this LRC facilitatory system can be applied to pulmonary rehabilitation of patients with COPD. Less
