“…Increases in the sagittal dimensions observed at the vertebral junctional zones within the spinal canal may have occurred because of dynamic alterations in intra- and intersegmental changes in the vertebral angles, increased apposition of the zygapophyseal joints, and bulging of the interlaminar ligament system with WB, as reported in the literature [ 16 , 17 ]. Such dynamic effects on the lumbar spinal canal with axially loaded spine observed with computed tomography–myelography and MRI in patients with sciatica have been reported and agree to the findings of this study involving asymptomatic individuals [ 6 , 11 ].…”

“…The relatively coronal orientation of the facet joints at this level may serve as struts that not only prevented the L5 listhesis at this junction but also acted as a fulcrum to help increase the L5–S1 angle, thereby “opening up” the foramen dimensions [ 20 – 22 ]. Interestingly, some studies have reported comparable changes in the intervertebral foraminal spaces as effects of axially loaded MRI of the lumbar spine on dural sac and lateral recesses [ 16 ].…”

Study Design: Testing between and within group differences and assessing reliability of measurements.Purpose: To study and compare lumbar spine morphology in supine and weight-bearing (WB) magnetic resonance imaging (MRI).Overview of Literature: Upright lumbar MRI may uncover anatomical changes that may escape detection when using conventional supine imaging. This study quantified anatomical dimensions of the lumbar spine in the supine and WB MRI, compared specific morphometric differences between them, and tested the intra-rater reliability of the measurements. Repeated measures analysis was used to compare within- and between-session measurements performed on the supine and WB images. Reliability and agreement were assessed by calculating intraclass correlation (ICC) coefficient.Methods: Data from 12 adults without any history of back pain were used in this study. Sagittal T2-weighted images of the lumbar spine were acquired in the supine and WB positions twice (in two separate sessions scheduled within a week). Linear, angular dimensions, and cross-sectional areas (CSAs) were measured using proprietary software. Supine and WB data acquired from the two imaging sessions were tested for intra-rater reliability. Quantified data were normalized for each session to test the significance of differences. ICC was calculated to test the reliability of the measurements.Results: Linear, angular, and CSA measurements demonstrated strong within-position (supine and WB) correlations (r -values, 0.75–0.97). Between-position (supine vs. WB) differences were significant for all measured dimensions (<i>p</i><0.05). Between-session measurements demonstrated a strong correlation (r -values, 0.64–0.83). Calculated ICC showed strong agreement among the measurements.Conclusions: Anatomical dimensions of the lumbar spine may demonstrate consistent and significant differences between supine and WB MRI for specific structural parameters.

“…This information can explain the patient’s symptomatology and significantly change the treatment plan accordingly. Patients with clinical symptoms that could not be explained by conventional supine MRI may benefit from alMRI, which can provide additional information that may affect the future treatment plan ( 21 ).…”

Background: MRI techniques of the lumbar spine have not provided data on the effect of gravity on the spine and on the relationship of anatomic structures during its action. Because conventional MRI examinations of the spine are usually performed in the supine position these are often exacerbated by standing upright and are not evident in the supine position the loading conditions differ from those known to cause symptoms in patients with lumbar instability. Axial loading imaging may improve diagnostics in the clinical management of LBP and lead to appropriate treatment decisions. Objective: The aim of this study is to determine the significance of alMRI in detecting the morphologic changes of the lumbar spine caused by axial loading and to compare it with conventional MRI images of the lumbar spine without loading. Methods: The study was conducted as a prospective, descriptive clinical trial. Imaging was performed with a MRI 1.5 T in the head-first supine position. Imaging was performed in two acts: without load and under load. Loading for alMRI was performed with the DynaWell L-Spine device. The onset of loading was 10 minutes before the start of alMRI. The loading continued throughout the imaging procedure. The height of the IV, AP and LL diameters of IV, IV disk surface area, DSCA and width of the IV foraminas before and under load was measured. Results: After evaluating the changes in the height and size of the lumbar disks, the size of the DSCA, and the narrowing of the intervertebral foramina significant differences were found between the images before and after axial loading. Conclusion alMRI provides information on morphological changes of all segments of the lumbar spine. This data represents significant information that can lead to more accurate and effective treatment of LBP.

“…Laboratory studies are generally reserved for patients with unexplained low back pain and are very useful in identifying malignant, infectious, and inflammatory diseases of the spine (32)(33)(34). Finally, simple and specific radiologic examinations can clearly determine the cause of specific low back pain (23,(35)(36)(37).…”

Introduction: Lumbar pain syndrome (LPS) is defined as pain or discomfort localized between the edge of the twelfth rib and the lower gluteal region, with or without spread to the lower extremities, and, depending on the etiology and degree of symptomatology, can have negative consequences and be one of the main reasons for work disability and absenteeism worldwide. The aim of this study was to determine the impact of exercise therapy on the activities of daily living of a person with LPS. Methods: This prospective, longitudinal, and randomized controlled trial was conducted from June 2014 to June 2016. It included 200 subjects with symptoms of LPS, both sexes, aged 30 to 50 years, sedentary and standing occupations, randomized and equally divided into two groups: Examined (n = 100) and the control group (n = 100). In this study, the Oswestry Low Back Pain Disability Questionnaire was used after clinical examination. Results: The percentage of disability according to the Oswestry disability index at the first examination was 31.78 ± 14.11% in the participants of the test group and 38.74 ± 17.48% in the participants of the control group (p = 0.002). After the second examination, the percentage of disability was 6.64 ± 3.15% in the test group and 23.92 ± 14.84% in the control group (p = 0.001). At the end of the examination, the percentage of disability was 2.36 ± 0.78% in the subjects of the test group and 13.82 ± 11.25% in the subjects of the control group (p = 0.001). A statistically significant difference was found in all three examinations, and the reduction in the percentage of disability was greater in the study group, p < 0.05. Conclusion: The research conducted showed that motion therapy procedures focused on achieving natural spinal mobility and improving trunk muscle strength are effective in reducing
