This pilot study evaluated the clinical feasibility of MR elastography (MRE)\u2010based slip interface imaging (SII) for visualizing myofascial mobility in CLBP\u2010MPS patients versus age\u2212\/sex\u2010\/BMI\u2010matched healthy participants. A new SII biomarker, maximal normalized displacement discontinuity (), was introduced, and the previously developed normalized octahedral shear strain (NOSS) map was used for comparison. Preliminary assessments of vibration\u2010frequency effects, repeatability, and group differences in inter\u2010muscular mobility were conducted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>MRE was conducted at 30, 60, and 90\u2009Hz to compare  with NOSS for visualizing inter\u2010muscular slip interfaces at the quadratus lumborum\u2010erector spinae (QL\u2010ES) and erector spinae\u2010multifidus (ES\u2010M) muscle boundaries at L3\u2010L4. Repeatability of  and NOSS was assessed at 30\u2009Hz (identified as the best\u2010performing frequency) using within\u2010subject coefficients of variation and a linear mixed\u2010effects model from within\u2010 and between\u2010day scans. Clinical feasibility was then assessed via Wilcoxon rank\u2010sum tests in six CLBP\u2010MPS patients and matched controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>at 30\u2009Hz exhibited superior delineation of slip interfaces compared to higher frequencies and NOSS.  demonstrated significantly lower variation and better repeatability than NOSS. Healthy participants showed continuous, well\u2010defined slip interfaces, whereas CLBP\u2010MPS patients displayed disrupted interfaces with significant mobility reduction at L4
