Changes in the motor control of trunk muscles have been identified in people with low back pain (LBP) including elite football players. Previous research has found functional differences in the anatomical regions of abdominal muscles; however, this has not been examined in football players with LBP. The aim of this study was to investigate if the ability to draw-in the abdominal wall is altered among football players with LBP, and to determine if there are functional differences between the middle and lower abdominal regions in participants with and without LBP. Forty-three elite Australian Football League players were imaged using magnetic resonance imaging (MRI) as they drew in their abdominal walls, and the trunk cross-sectional area (CSA) was measured in relaxed and contracted states. At the lower region, participants with LBP (1.1%) reduced their trunk CSA to a lesser extent than those without LBP (3.2%) (P = 0.018). The results also showed that the draw-in of the abdominal wall was smaller in Region 1 (8.8%) compared to Region 2 (16.0%) and Region 3 (19.7%) (P < 0.001). This study provides evidence of regional differences in motor control and altered control of the lower region in participants with LBP. This may direct physiotherapists, especially those treating athletes, to focus on the lower abdominal region in those with LBP.
包括精英足球运动员在内的腰痛（LBP）患者已被发现存在躯干肌肉运动控制方面的变化。先前的研究已经发现腹部肌肉解剖区域存在功能差异；然而，尚未在患有LBP的足球运动员中对此进行研究。本研究的目的是调查患有LBP的足球运动员收腹能力是否改变，并确定有无LBP的参与者中腹部中下部区域之间是否存在功能差异。43名澳大利亚精英足球联赛球员在收腹时接受了磁共振成像（MRI）检查，并测量了他们在放松和收缩状态下的躯干横截面积（CSA）。在下部区域，患有LBP的参与者（1.1%）的躯干CSA缩小程度低于未患LBP的参与者（3.2%）（P = 0.018）。结果还表明，与第2区域（16.0%）和第3区域（19.7%）相比，第1区域（8.8%）的腹壁内收幅度更小（P < 0.001）。本研究提供了运动控制存在区域差异以及LBP参与者下部区域控制改变的证据。这可能会引导物理治疗师，尤其是治疗运动员的物理治疗师，将注意力集中在患有LBP的人的下腹部区域。
