This study has conducted to investigate the changes in the mobility of the three thoraco-abdominal lines(TAMs) during breathing and in the thoracic and lumbar spine mobility(TSM, LSM) during trunk forward flexion, after breathing pattern correction. The 30 subjects with lumbar instability(LI) have divided into the breathing pattern correction exercise(BPC) group of 15 subjects and the lumbar stabilization exercise(LSE) group of 15 subjects and performed each exercise for 40 minutes at one session, and a total of 18 sessions were applied for 6 weeks. As a result, The BPC group during breathing showed a significant increase in all TAMs(p<.001) and in the TSM(p<.001) than the LSE group. Besides, had a more decrease in the LSM than the LSE group(p<.001). The BPC showed high positive correlations with TAMs(rest: r=.868, forced: r=.870) and the TSM(r=.672) and had a negative correlation with the LSM(r=-.420). Based on this result of the study, the authors believe that the BPC in LI people could decrease the lumbar flexion mobility when they have motion of trunk forward flexion with promotions in the thoracic spine and rib joint mobility by improvements in relative mobility of thoraco-abdominal lines.

This study develops a coverall design for the body shape and movement of infants. This research analyzed these processes: 1. The current coverall styles preferred for infants. 2. The appropriate products for the real size, body shape, movement, and fit of infants. 3. The observations of the 6 months to 9 months movement and development of infants. 4. The design and creation of a new coverall base in this study, and to check the suitable test the developed coverall design for the infant. The result of this study are: A coverall for infants that lie or crawl on the floor must avoid opening in the center front and a gore has to be added at the crotch of the pants for the better movement of infants. These ways provide infants a neat appearance and easy movement. The test of developed designs shows that the developed coverall design covers the size gap of the trunk loop according to the growth of the infant and the movement of the legs; in addition it provides a positive aesthetic effect. The waistline in the developed coverall (a waistline that should exist lower than the body waistline of the infant) can reduce seam stress because the pressure of the seam line can be absorbed in a dipper. It is one of the suitable design points for infants lying prone all day long in this study.

This study examined the correlation between the respiratory pattern change (RPC) and abdominal mobility (AM) according to the positive result of the subjective lumbar instability factor (SLIF) in people with chronic low back pain (CLBP). Thirty-six adults with CLBP participated in this study. Twenty-eight items of the SLIFs were examined, and the subjects were divided into three groups according to the positive response numbers (PRN). After the change lists were scored, three RPC scores [costo-diaphragmatic RPC (CDRPC), breath hold change (BHC), and total RPC (TRPC)] were obtained. The abdominal mobility (AM) was measured between the maximal inspiration and exhalation at the xiphoid (AM1) and the 10^th rib (AM2) level of the trunk. The results showed that the RPC score and AM were compared according to the positive response number of SLIF, and the relationship between them was analyzed. A positive correlation was observed between the SLIF positive response number and CDRPC score, BHC score, and total RPC score, and a negative correlation was observed between the SLIFs positive response number and AM1 and AM2. Based on the results of this study, the combination of SLIF positive responses can be a predictor of non-physiological respiratory pattern changes in people with CLBP. Clinically, this prediction is expected to help save time for screening and improve the efficiency of therapy.
