Examines associations between multifidus morphology and pain intensity in individuals with low back pain, suggesting implications for treatment.
PURPOSE: This study examined whether multifidus muscle morphology differs according to the specific site of lower back pain (LBP) and explored its associations with pain intensity, disability, and psychosocial factors in individuals with subacute or chronic LBP.Although muscle atrophy in LBP has been widely reported, the relevance of multifidus structure to localized pain patterns remains unclear.METHODS: Sixty-three participants with LBP were classified into unilateral left, unilateral right, bilateral, or central pain groups.Multifidus cross-sectional area (CSA) and asymmetry ratio (AR) at the L4-5 level were assessed †Corresponding
