“…According to the Asian standards of the World Health Organization (WHO) regulations, if BMI is in the range from 25.0 to 29.9, then it is to be defined as being obese 10 ) . The participants in this test with BMI mean (26.0 ± 4.7) belong obesity group, but their 10th rib with the highest correlation value (0.86) during respiratory movement were consistent with reports of both Carla et al 7 ) . Meyer suggested that a correlation coefficient r≥0.8 means a high correlation, r=0.6–0.8 means a good correlation, r=0.4–0.6 means a moderate correlation, and r≤0.4 means a poor correlation 11 ) .…”

[Purpose] The purpose of this study is to find the best body spots on the chest and abdomen wall to obtain the correlated indicators to the vital capacity. [Subjects and Methods] Thirty healthy male staff of the center served as the participants were advised to conduct a breathing movement using spirometer and a wearable strain sensor (WSS) respectively, which was the measured at four spots on chest and abdomen wall from maximal end of inspiration to maximal end of expiration. The Pearson’s correlation analysis was conducted to find the correlation of the data obtained respectively by the WSS and spirometer. [Results] The correlation of the mobility data at the four body spots to the vital capacity data were calculated for each level by means of Pearson’s correlation coefficient, which showed that the values at each body spot were positive significant correlations and the highest value was at the 10th rib. [Conclusion] There was a correlation between the mobility data of the chest and abdomen obtained by the WSS and the vital capacity data obtained by the spirometer, for which, the 10th rib is the best body spot to detect the positive significant correlation.

“…Measurement of chest expansion is a simple and practical method for assessing subjects’ respiratory function. Shobo et al found that there was a highly positive correlation between chest expansion and changes in the chest volumes at all indicated locations 11 , 12 ) . However, measuring devices of chest expansion were both 3-dimensional motion analyzer and a spherical reflective marker, which were required to conduct in a special experimental environment.…”

[Purpose] The purpose of this research was to verify the reliability and validity of measuring respiration movement using a wearable strain sensor (WSS) which has been developed newly for clinical objective assessment. [Subjects and Methods] The 21 healthy male students were advised to conduct a breathing movement using measuring tape (MT) and WSS respectively, which was the measured at four locations on chest and abdomen wall. The different degree of chest expansion from maximal end of expiration to maximal end of inspiration was confirmed at each location. The intra-rater ICC (1,1) with 95% confidence interval was used to assess the test-retest reliability, Pearson’s correlation analysis was performed to establish the validity. [Results] All ICC values for intra-rater reliability were from 0.94 to 0.98 at all locations, which means that there is a high correlation. All values for validity showed significantly positive, indicating that there is a correlation between the measuring tape and WSS at four locations. [Conclusion] Compared to the measuring tape, WSS has been proved to have high reliability and validity. The finding of this research indicated that WSS is reliable to use for objective measurement of respiratory movements on the chest and abdomen wall in clinical assessment.

[Purpose] Some patients with respiratory disease exhibit asymmetrical movement of the thorax. The purpose of this study was to investigate the relationship of thoracic configuration with changes in thoracic volume in 13 sedentary healthy men. [Subjects and Methods] In upright sitting, 84 reflective markers were placed on the anterior and posterior aspects of the trunk to record thoracic volume during quiet and volitional deep breathing. Using a three-dimensional motion analyzer, the difference in volume within the upper and lower hemithoraces was measured. For calculation of the thoracic volume six imaginary hexahedra were visualized for the upper and lower thorax using four reflective markers for each on the anterior and posterior aspects of the thorax. Each hexahedron was then divided into three imaginary triangular pyramids to calculate positional vectors. Finally, the volume for both the hexahedra and triangular pyramids was calculated. Four thoracic volumes were obtained. [Results] The findings showed that the left upper and right lower hemithorax yielded significantly larger thoracic volumes. [Conclusion] In conclusion the left upper and right lower hemithoraces were found to expand more than their corresponding sides. Understanding the characteristics of thoracic excursion during quiet and volitional deep breathing could be of value in assessment and instruction of breathing techniques to patients.
