“…The results showed that FVC, FEV1.0 and PFR were significantly lower at 30° PPTS than those at 0° PPTS. Previous studies have reported that PPTS leads to decreased respiratory function 13,14) . Takeda et al 20) reported a statistically significant decrease in FVC at 30° PPTS compared to the control group, which is consistent with the results of this study.…”

“…On the other hand, PPTS is suggested to be strongly associated with certain respiratory function. Hwang and Kim 13) and Lin et al 14) showed that forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1.0), and peak flow rate (PFR) were lower in the PPTS. FVC, FEV1.0, and PFR are used for diagnosis of lung function and respiratory diseases.…”

Effects of the posterior pelvic tilt sitting posture on thoracic morphology and respiratory function

We investigated how differences in pelvic angle in the posterior pelvic tilt sitting posture simultaneously affect the thoracic morphology and the respiratory function. [Participants and Methods] The participants were 18 healthy young males. We positioned the pelvis at 0°, 10°, 20°, and 30° of posterior tilt, following which the thoracic expansion volume ratio, thoracic spine tilt angle, and respiratory function were measured. We calculated the thoracic volume and thoracic spine tilt angle by measuring the amount of displacement of reflective markers attached to the thoracic area using the Vicon MX 3D-analysis system. Respiratory function was measured by spirometry. [Results] The expansion volume ratio decreased significantly in response to 10-30° posterior pelvic tilt sitting at the mid-thorax and 30° posterior pelvic tilt sitting at the lowest thorax. The upper thoracic spine level showed a change in anterior tilt at 10-30° posterior pelvic tilt sitting, whereas the lower thoracic spine level showed a change in posterior tilt at 30° posterior pelvic tilt sitting. Respiratory function was significantly lower at 30° posterior pelvic tilt sitting than at 0° posterior pelvic tilt sitting. A positive correlation between thoracic expansion volume ratio and respiratory function was found at 30° posterior pelvic tilt sitting. [Conclusion] Changes in thoracic spine tilt angle due to posterior pelvic tilt sitting may restrict the expansion of thoracic motion during respiration, thereby affecting respiratory function.
