“…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. The study also found a positive correlation between the rate of change in respiratory function and the total chest dilation of the D-levels at 30° PPTS.…”

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.

Effect of Using a Spine Mat on Chest Expansion, Respiratory Function, and Respiratory Muscle Strength

et al. 2023

View full text Add to dashboard Cite

This study compared the results of chest expansion, respiratory function, and respiratory muscle strength before and after an intervention using a spine mat. [Participants and Methods] We enrolled 30 healthy adult men (age 20.2 ± 1.6 years). For the intervention, participants lay in a supine position on a spine mat so that it adhered to the thoracic spine. The primary outcome variables were spinal alignment, thoracic expansion, and respiratory function.[Results] Following the intervention, a significant decrease was observed in the thoracic kyphosis angle. The intervention significantly increased chest expansion. Respiratory function tests revealed a significant increase in the inspiratory capacity (IC), and respiratory muscle strength showed a significant increase in the maximum inspiratory mouth pressure (PI max). [Conclusion] The results suggest that the use of a spine mat can improve chest expansion, the IC and the PI max value.
