“…Volume data collected during deep breathing in healthy adults demonstrated that the distribution of compartmental breathing volumes is posture independent. The volume changes in both hemithoraxes are similar, as demonstrated by Nozoe et al [65] . Moreover, Wang et al [66] demonstrated that the motion of all 3 CW compartments is highly correlated with diaphragmatic movement distance in the inspiratory phase during both quiet and deep breathing.…”

Background: Optoelectronic plethysmography (OEP) is a non-invasive motion capture method to measure chest wall movements and estimate lung volumes. Objectives: To provide an overview of the clinical findings and research applications of OEP in the assessment of breathing mechanics across populations of healthy and diseased individuals. Methods: A bibliographic research was performed with the terms “opto-electronic plethysmography,” “optoelectronic plethysmography,” and “optoelectronic plethysmograph” in 50 digital library and bibliographic search databases resulting in the selection of 170 studies. Results: OEP has been extensively employed in studies looking at chest wall kinematics and volume changes in chest wall compartments in healthy subjects in relation to age, gender, weight, posture, and different physiological conditions. In infants, OEP has been demonstrated to be a tool to assess disease severity and the response to pharmacological interventions. In chronic obstructive pulmonary disease patients, OEP has been used to test if patients can dynamically hyperinflate or deflate their lungs during exercise. In neuromuscular patients, respiratory muscle strength and chest kinematics have been analyzed. A widespread application of OEP is in tailoring post-operative pulmonary rehabilitation as well as in monitoring volume increases and muscle contributions during exercise. Conclusions: OEP is an accurate and validated method of measuring lung volumes and chest wall movements. OEP is an appropriate alternative method to monitor and analyze respiratory patterns in children, adults, and patients with respiratory diseases. OEP may be used in the future to contribute to improvements in the therapeutic strategies for respiratory conditions.

“…We found that the anteroposterior diameters were smallest in the supine position with a mediolateral symmetrical and elliptical shape, whereas in the lateral recumbent position, the anteroposterior diameters were large with small mediolateral diameters and round shapes, indicating that the mediolateral chest-wall configuration was asymmetrical. Regarding the changes in configuration observed here, it is believed that changing to the lateral recumbent position may have caused the mediastinum to shift in a sagittal plane direction 6 , 12 ) . On the basis of the results of the AB diameter and horizontal plane configuration, it is believed that changes in the direction of the force of gravity along with changes in posture cause a shift in the abdominal organs, which may expand the abdominal wall and change the configuration 14 ) .…”

“…Reflective markers (9 mm in diameter) were pasted on the surface of the subject’s body. In accordance with previous studies, the reflective markers were pasted on 66 sites in the supine position, 81 sites in the right lateral recumbent position (lateral recumbent position), and 86 sites in the sitting position 8 , 12 ) . Furthermore, the supine and lateral recumbent positions were on the floor, and, for the lateral recumbent position, the subject was instructed to prop the left upper arm on a cushion placed on the greater trochanter in order to support the arm 12 ) .…”

“…However, few reports have thoroughly examined the magnitude of chest motion at each location, i.e., the anterior, dorsal, and lateral surfaces 6 ) . In particular, posture has been reported to affect chest-wall motion 10 , 11 , 12 ) , and it is likely that local motion in the chest wall changes in various postures; however, De Groote et al only reported results for the sitting posture. Some reports examined local chest-wall motion in various postures using magnetometry 10 ) .…”

[Purpose] The purpose of this study was to clarify the impact of postural changes during tidal breathing on the configuration and motion of chest-wall in order to further breathing motion evaluation. [Subjects and Methods] Chest-wall configuration and motion in the supine, right lateral, and sitting positions were measured using optoelectronic plethysmography in 15 healthy adult men. [Results] The anteroposterior diameters of the chest wall were significantly lower in the supine position for the pulmonary and abdominal rib cages, whereas the mediolateral diameters in the lateral position were lowest for the abdominal rib cage. Regarding chest-wall motion, both craniocaudal and anteroposterior motions of the anterior surface of the pulmonary and abdominal rib cages were significantly greater in the sitting position. Regarding motion of the left lateral abdominal rib cage, lateral motion was greatest in the lateral position. [Conclusion] Chest-wall configuration and motion changed according to posture in healthy men, particularly in the pulmonary and abdominal rib cages.

“…Previous studies have analyzed the effects of posture on chest wall kinematics and lung volume in various postures, including the supine and prone positions and a shift from the seated position to the supine position ( Aliverti et al, 2001 ; Romei et al, 2010 ). In addition, the changes of chest wall volume in the lateral position have also been investigated ( Nozoe et al, 2014 ). However, the changes in chest wall kinematics during the thoracic rotation and side-bending postures have not been compared.…”

Postural changes induce changes in chest wall kinematics and eventually pulmonary function, and affect chest wall shape and chest motion. This study aimed to examine the effects of postural change on changes in the chest wall during respiratory muscle training. Using a repeated measures design, this study followed 13 healthy adults (13 men; mean age, 23.73 years). All participants performed four postures (neutral, full trunk rotation, half-range trunk rotation, and lateral ribcage shift postures) during respiratory muscle training. The chest wall movement during the four postures was measured using a three-dimensional motion-analysis system during respiratory muscle training. Surface electromyography data were collected from the diaphragm and sternocleidomastoid muscles, and the asymmetric ratio of muscle activation was calculated based on the collected data. The chest wall movements of the upper costal and middle costal region were greater in the neutral posture than in the full rotation, half rotation, and lateral ribcage shift postures (P<0.05). The respiratory muscle activation on diaphragm of left was greater in the full rotation posture than in the neutral posture, half rotation, and lateral ribcage shift postures (P<0.05). The asymmetric ratio of muscle activation was greater in the full rotation posture than in the neutral posture, half rotation, and lateral ribcage shift postures (P<0.05). This study verified that postural change during respiratory muscle training may affect chest wall movement and muscle activation. Thus, this study recommends respiratory muscle training to be performed in neutral posture.
