Abstract | Study Design: Cross-sectional, observational study. Objectives: To investigate the cross-sectional area (CSA) of trunk muscles in professional ballet dancers with and without low back pain (LBP). Background: LBP is the most prevalent chronic injury in classical ballet dancers. Research on nondancers has found changes in trunk muscle size and symmetry to be associated with LBP. There are no studies that examine these changes in ballet dancers. Methods: Magnetic resonance imaging was performed in 14 male and 17 female dancers. The CSAs of 4 muscles (multifidus, lumbar erector spinae, psoas, and quadratus lumborum) were measured and compared among 3 groups of dancers: those without LBP or hip pain (n = 8), those with LBP only (n = 13), and those with both hip-region pain and LBP (n = 10). Results: Dancers with no pain had larger multifidus muscles compared to those with LBP at L3–5 (PPPP>.05). The CSAs of the other muscles did not differ between groups. The psoas (PPP = .03). |
