Purpose: Numerous studies have applied a variety of methods to assess paraspinal muscle degeneration. However, the methodological differences in imaging evaluation may lead to imprecise or inconsistent results. This article aimed to provide a pragmatic summary review of the current imaging modalities, measurement protocols, and imaging parameters in the evaluation of paraspinal muscle fat infiltration (FI) in MRI studies.Methods: Web of Science, EMBASE, and PubMed were searched from January 2005 to March 2020 to identify studies that examined the FI of paraspinal muscles on MRI among patients with lumbar degenerative diseases.Results: Intramyocellular lipids measured by magnetic resonance spectroscopy and FI measured by chemical-shift MRI were both correlated to low back pain and several degenerative lumbar diseases, whereas results on the relationship between FI and degenerative lumbar pathologies using conventional MRI were conflicting. Multi-segment measurement of FI at the lesion segment and adjacent segments could be a prognostic indicator for lumbar surgery. Most studies adopted the center of the intervertebral disc or endplate as the level of slice to evaluate the FI. Compared with visual semiquantitative assessment, quantitative parameters appeared to be precise for eliminating individual or modality differences. It has been demonstrated that fat CSA/total CSA (based on area) and muscle-fat index (based on signal intensity) as quantitative FI parameters are associated with multiple lumbar diseases and clinical outcomes after surgery. Conclusion:Having a good command of the methodology of paraspinal muscle FI on MRI was effective for diagnosis and prognosis in clinical practice.

“…According to the above, we know that although the correlation between spinopelvic parameters and LBP has been con rmed by many studies, the speci c reason remains unclear. It is worth noting that lumbar multi dus muscles (LMMs) are considered to be the most important muscle for lumbar segmental stability [25] , and LBP is related to fat in ltration in LMMs [26] . However, fat in ltration may be an important feature of degenerating LMMs that are affected in lumbar operations [27] .…”

Background: Numerous studies have reported that pelvic functional training is beneficial for improving low back pain (LBP) in patients with lumbar disc herniation (LDH) after lumbar surgery and that fat infiltration of the lumbar multifidus muscles (LMMs) is one of the most important reasons for residual LBP after surgery. However, little is known about the exact relationship among residual LBP, spinopelvic parameters and the area of fat infiltration in LMM after lumbar surgery. This study aimed to confirm the relationship among residual LBP, spinopelvic parameters and the area of fat infiltration in LMM and to investigate why pelvic functional training can relieve pain symptoms in patients with LDH after lumbar surgery.Methods: One hundred forty-three patients with LDH were involved in this study. Clinical data were collected from a system of digital medical records, including age, gender, course, and weight. On the MRI images, the cross-sectional areas (CSAs) of bilateral fat infiltration in the LMM were measured using a picture archiving and communication system (PACS). On the X-ray, sacral slope (SS), pelvic tilt (PT) and pelvic incidence (PI) were also measured by PACS. Pearson correlation analysis was applied to analyse the differences between CSA of fat infiltration in LMM and spinopelvic parameters, and ROC curves were used to reflect the degree of fat infiltration in LMM with spinopelvic parameters.Results: One hundred and twenty-five patients met the inclusion criteria. SS and PI were positively correlated with CSA of fat infiltration in LMM at L3-4 and L4-5 (p < 0.01). At L4-5, SS and PI demonstrated significant positive correlation with the CSA of fat infiltration in the LMM (0.5 < | r | < 0.8). PI also exhibited a significant positive correlation with VAS (0.5 < | r | < 0.8), but SS had a low correlation with VAS (0.3 < | r | < 0.5). At L4-5, only the PI had a significant ROC curve (AUC = 0.836) with a cut-off point score of 0.556 and sensitivity and specificity values of 62.8% and 87.4%, respectively. However, at L3-4 and L5-S1, the AUCs of the ROC curves were all < 0.7 for SS, PT and PI. Conclusions: The wider pelvic anterior tilt, the more severe fat the infiltration in LMM. Residual LBP can be relieved by spinopelvic correction training potentially due to the improvement of fat infiltration in LMM.

“…VAS scale is a scale used to assess pain, usually on a scale of 1–10, with a lower score indicating less pain intensity, and conversely, a higher score indicating greater pain intensity [ 19 ]; ODI scale is a scale used to assess dysfunction and typically has 10 questions, each corresponding to a score of 0–5 on a 50-point scale, with a lower score representing better functioning and, conversely, a higher score representing a higher degree of dysfunction [ 20 ]. The straight leg raise is often used to check the patient’s sciatic nerve, when patients supine leg lifts, along with the rising of the leg Angle, such as patients with sciatic nerve problems, can appear the numbing pain (usually within 70°) [ 21 ].…”

Background Low back pain (LBP) is a leading cause of disability. Neuromobilization (NM) as a physical therapy technique, offers some degree of symptom improvement. However, some studies have shown that NM can significantly reduce the symptoms of LBP, while others have failed to find similar positive effects. Objective This study aims to investigate the effectiveness of NM for LBP. Data sources A literature search was conducted across five databases (MEDLINE, Embase, Cochrane Library, PubMed, and Web of Science) from their inception to December 2023. Study main measures assessed pain, disability, and straight leg raise angle to determine the degree of improvement in patients. Results Seven randomized controlled trials were included in the analysis. The findings indicated that NM interventions in patients with LBP were more effective than control groups in improving Visual Analog Scale scores (mean difference = 0.62, 95% CI (0.03, 1.21)) and Oswestry Disability Index scores (mean difference = 7.54, 95% CI (4.98, 10.10)). There was no significant difference in straight leg raise results (mean difference = 0.18, 95% CI (-0.08, 0.44)). Conclusions NM demonstrated effectiveness in improving Visual Analog Scale and Oswestry Disability Index outcomes in patients with LBP, but straight leg raise outcomes are still uncertain and until more high-quality studies are included, the effectiveness of NM for SLR remains unknown.
