“…The same holds true for the forward leaning position with head support, enabling the accessory neck muscles to assist inspiration. The forward-leaning sitting position facilitates increases in the diameter or circumference of the rib cage and lung volume; consequently, individuals in this position experience improved dyspnea 15 , 16 , 17 ) . These facts may be the reason that forward-leaning sitting was chosen as most comfortable position in patients in GOLD stage 4.…”

Effect of manual chest wall compression in participants with chronic obstructive pulmonary disease

et al. 2018

[Purpose] Pulmonary rehabilitation is appropriate for most individuals with chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation consists of conditioning and exercise therapy. Conditioning includes relaxation, breathing exercises, and manual chest wall compression during expiration (CWC). CWC improves the symptoms in individuals with respiratory disease who have undergone mechanical ventilation. However, evidence supporting the effectiveness of CWC for COPD has been insufficient. This study aimed to determine physiological responses to CWC in participants with COPD. [Participants and Methods] Twenty-nine participants with COPD were included in the study. Manual CWC techniques were performed in a comfortable position chosen by the participants (sitting, forward-leaning (sitting), or semi-Fowler’s). Ventilatory parameters, occlusion airway pressure (P0.1), and dyspnea were assessed using a visual analog scale and were compared before and during CWC. [Results] During manual CWC, oxygen consumption, carbon dioxide production, end-tidal carbon dioxide concentration, and dyspnea were significantly decreased; however, P0.1 was not affected. [Conclusion] Manual CWC for COPD had an immediate physiological effect, including a decrease in dyspnea that may have been facilitated by a reduced workload of the respiratory muscles. Thus, manual CWC may be effective for dyspnea by reducing oxygen consumption in the respiratory muscles.

[Purpose] To investigate the effects of inspiratory muscle training on respiratory capacity and walking ability in subacute stroke patients. [Subjects and Methods] The subjects were randomly assigned to an experimental group (n=6) or a control group (n=6). Patients in the experimental group received inspiratory muscle training for 30 minutes (six sets of five-minutes) and traditional physical therapy once a day, five days a week, for four weeks. The control group received aerobic exercise for 30 minutes and traditional physical therapy for 30 minutes a day, five days a week, for four weeks. [Results] After the intervention, both groups showed significant improvements in the forced vital capacity, forced expiratory volume in one second, 10-meter walking test, and six-minute walking test over the baseline results. There were significant between-group differences for the forced vital capacity, forced expiratory volume in one second, and six-minute walking test. No statistically significant differences were observed for measures of saturation pulse oximetry oxygen and 10-meter walking test between the groups. [Conclusion] These findings gave some indications that inspiratory muscle training may benefit in patients with subacute stroke, and it is feasible to be included in rehabilitation program with this population.

“…Ogino et al 10 ) reported that the most comfortable posture for COPD patients was a forward bending posture of 28.4°. They compared the differences in pulmonary functions of COPD patients in each of the standing position, trunk forward bending position, and trunk forward bending with arm-bracing position.…”

“…Willeput and Sergysels 8 ) reported that the length-tension relationship of the diaphragm and the mechanical coupling of the rib cage were improved in the trunk forward bending position. This body forward bending with arm-bracing position has been reported to relieve dyspnea and expiratory flow limitation of COPD patients, and to increase lung capacity and muscle strength of the respiratory muscles 7 , 9 , 10 ) .…”

[Purpose] The purpose of this study was to examine whether a trunk forward bending angle in sitting position affected slow vital capacity (SVC). [Subjects and Methods] The subjects of this study were 18 healthy college students to whom the study’s methods and purpose were explained and their agreement for participation was obtained. Slow vital capacity was measured using spirometry (Pony FX, COSMED Inc., Italy), repeatedly at a body bending angle of 0°, 15°, and 30° in the sitting position. [Results] Vital capacity, expiratory reserve volume, and inspiratory reserve volume were significantly different according to the trunk forward bending angle. There were no statistically significant differences in tidal volume and inspiratory capacity. [Conclusion] The results demonstrated that the body bending angle of 15° in the sitting position was the most effective angle for increasing lung volume.
