“…In the group that performed SBEE after fatiguing the lumbodorsal muscles, the shear modulus was lower than before the SBEE. In our previous studies [ 13, 30 ], changes in hemodynamics of the lumbar muscle group were assessed after the performance of this exercise. The result showed that improved blood flow in the multifidus muscles.…”

BACKGROUND: In low back pain, multifidus muscle fibers reportedly exhibit increased stiffness. Low back pain was associated with lumbodorsal muscle fatigue. There is no report of using shear modulus to verify the mechanism of an immediate effect of exercise on low back pain. Here, temporary lumbodorsal muscle fatigue was created, simulating fatigue-related nonspecific low back pain. OBJECTIVE: To assess the effect of standing back extension exercise on fatigued lumbodorsal muscle based on the results of multifidus muscle elasticity measured using shear wave elastography. METHODS: Thirty-three healthy subjects were randomly divided into three groups. The subjects performed the Biering-Sorensen test as the fatigue-task of the lumbodorsal muscle before the standing back extension exercise. The fatigue-exercise group exercised five sets after completing the fatigue-task. The fatigue-non-exercise group remained standing for the same duration as the fatigue-exercise group without doing the exercise after the fatigue-task. The non-fatigue-exercise group exercised five sets of without performing the fatigue-task. As intra-group and inter-group factors, the shear modulus of the multifidus muscle was compared before and after the exercise. RESULTS: The shear modulus of the multifidus muscle after the standing back extension exercise was significantly lower in the fatigue-exercise group, and no significant decrease was observed in the fatigue-non-exercise and non-fatigue-exercise group. CONCLUSIONS: The standing back extension exercise improved the shear modulus of the fatigued multifidus muscle. Therefore, it was suggested that the change in the elasticity of fatigued muscle might lead to the prevention of low back pain caused by muscle fatigue.

“…Therefore, in our previous studies, lumbodorsal muscle group hemodynamics was examined in repeated trunk extension movement using near-infrared spectroscopy. Hence, improved blood flow in the area was reported, corresponding to 1.5 cm below the skin [ 13 ].…”

“…Kumamoto et al studied the changes of oxyhemoglobin and electromyography in standing stretching exercise and found that standing stretching can improve hemodynamic performance, but excessive exercise will lead to a decrease of hemodynamic changes. Though patients with muscle ischemia should be more cautious when doing such exercises [85]. Besides that, based on taking protective measures, older adults can also benefit from exercise [86], and the inflammatory indexes of low back pain patients will decrease after exercise [87].…”

This review summarizes recent research progress in the clinical features, image manifestations, and pathological mechanism of multifidus injury. After a brief introduction to the fiber classification, innervation, blood supply, and multifidus function, some factors of multifidus injury, consisting of denervation, intraoperative incision selection and traction, and lumbar degenerative disease are overviewed. In addition, the clinical index of multifidus injury including myoglobin, creatine kinase, IL-6, C-reactive protein, the cross-sectional area of multifidus, the degree of fat infiltration, and intraoperative biopsy are summarized. Furthermore, we recommend that patients with chronic low back pain should take the long-term exercise of lumbodorsal muscles. Finally, some remaining issues, including external fixation and the imaging quantitative evaluation criteria of multifidus, need to be further explored in the future.
