“…Sustained postures or incorrect movement habits may modify the demands made of the involved muscles, leading to changes in strength, flexibility, stiffness or activation patterns 4,5 . As a consequence, changes in movement patterns may emerge, thus spreading the physical stresses across various structures, which results in impairments of the muscular and skeletal systems 1,2 .…”

“…Adequate muscular activation patterns, when the synergic muscles are activated in an appropriate temporal order, are recognized to be important for the effective functioning of the lumbar spine 5 . Even if these muscles have adequate strength and, if the nervous system does not activate them at the right moment and with an adequate intensity, movement impairments can still result 4 , and contribute to low back pain (LBP).…”

“…Moreover, the muscles of the local stabilization system are located near the vertebral column and can delicately regulate segmental movements 18) . The increased tension in these muscles promotes a compression force between each lumbar muscle and enhances stabilization [19][20][21][22] . Stevens et al reported that the IO/RA ratio was very high because of the relatively small activity of RA during unstable supine bridging exercises 14) .…”

Abstract. [Purpose] This study aimed to investigate the differences in activities and ratios of the muscles internal oblique (IO), rectus abdominis (RA), multifidus (MF), and the thoracic part of the iliocostalis lumborum (ICLT) muscle between unstable supine and prone bridging exercises in individuals with low back pain (LBP). [Methods] A convenience sample of 14 individuals with LBP (7 men and 7 women) performed supine and prone bridging exercises. Surface electromyography signal amplitudes of the dominant trunk muscles during the 2 types of exercises were measured of all subjects.[Results] During the supine bridging exercise, the activity of the MF and ICLT and the IO/RA ratio were significantly higher than those during the prone bridging exercise. In contrast, the activities of IO and RA were significantly higher during the prone bridging exercise than that during the supine bridging exercise. [Conclusion] This study showed the differences in trunk muscle activities and ratios between unstable supine and prone bridging exercises in individuals with LBP. The information presented here is important for investigators who use lumbar stabilization exercises as an evaluation tool or a rehabilitation exercise for individuals with LBP.

“…Lower back pain is caused by the wrong mobilization sequence between the superficial stabilizer and deep stabilizer muscles and an imbalance in the muscular lengths 3) . Thus, in order to stabilize the lumbar muscles, the cooperative contraction of the superficial stabilizer and deep stabilizer muscles and the strengthening of the deep stabilizer muscle which is directly connected to the spine are needed 4) .…”

Abstract.[Purpose] The purpose of this study was to investigate the effects of a resistance and stabilization complex exercise on the strength and cross-sectional area of lumbar muscles of typical adults in their twenties. [Subjects and Methods] For this study, 14 male adults in their twenties were chosen and randomly assigned to either the resistance exercise group (REG, n=7) or the resistance and stabilization exercise group (RSEG, n=7). They then exercised for 50 minutes three times a week for 8 weeks.[Methods] Pegasus was used to measure the strength of the lumbar muscles of the normal adults and computed tomography (CT) images were taken and compared to examine the changing crosssectional areas of the lumbar muscles.[Results] Both groups showed a significant increase in the strength of their lumbar muscles. For the cross-sectional area of the lumbar muscles, only the superficial stabilizer muscle of the REG group showed a significant increase, whereas both the superficial stabilizer and the deep stabilizer muscles of the RSEG group showed a significant increase.[Conclusion] The resistance and stabilization complex exercise for the lumbar muscles had positive effects on both the strength of the lumbar muscles as well as on the cross-sectional areas of the superficial stabilizer and deep stabilizer muscles. Therefore, resistance and stabilization complex exercise appears to be an effective exercise program for the prevention of lower back pain.
