In Australian football, lower limb injuries have had the highest incidence and prevalence rates. Previous studies have shown that football players with relatively more severe preseason and playing season hip, groin, and thigh injuries had a significantly smaller multifidus muscle compared with players with no lower limb injuries. Rehabilitation of the multifidus muscle, with restoration of its size and function, has been associated with decreased recurrence rates of episodic low back pain and decreased numbers of lower limb injuries in football players. Assessment of multifidus muscle size and function could potentially be incorporated into a model that could be used to predict injuries in football players.
To examine the robustness of multifidus muscle measurements as a predictor of lower limb injuries incurred by professional football players.
Cohort study; Level of evidence, 2.
Ultrasound examinations were carried out on 259 male elite football players at the start of the preseason and 261 players at the start of the playing season. Injury data were obtained from records collected by the Australian Football League (AFL) club staff during the preseason and the playing season.
Decreased size of the multifidus muscle at L5 consistently predicted injury in the preseason and playing season. Asymmetry of the multifidus muscle and low back pain were significantly related to lower limb injuries in the preseason, and having no preferred kicking leg was related to season injuries. Seasonal change in the size of the multifidus muscle indicating a decrease in muscle mass was linked to injury. Sensitivity and specificity of the model were 60.6% and 84.9% for the preseason and 91.8% and 45.8% for the playing season, respectively.
A model was developed for prediction of lower limb injuries in football players with potential utility for club medical staff. Of particular note is the finding that changes in muscle size from the preseason to the playing season predicted injury.
As size of the multifidus muscle has been shown to be modifiable with training and has been associated with reduced pain and occurrence of injuries, this information could be incorporated in current programs of injury prevention.
在澳大利亚足球中，下肢损伤的发生率和患病率最高。先前的研究表明，与没有下肢损伤的球员相比，季前赛和比赛赛季中髋关节、腹股沟和大腿受伤相对更严重的足球运动员，其多裂肌明显较小。多裂肌的康复，包括其大小和功能的恢复，与足球运动员间歇性腰痛复发率的降低和下肢损伤次数的减少有关。多裂肌大小和功能的评估可能被纳入一种模型，可以用来预测足球运动员的受伤。
检查多裂肌测量作为预测职业足球运动员下肢损伤的指标的稳健性。
队列研究；证据水平，2 级。
在季前赛开始时对 259 名男性精英足球运动员和 261 名运动员进行了超声检查，在比赛赛季开始时对 261 名运动员进行了超声检查。损伤数据是从澳大利亚足球联赛（AFL）俱乐部工作人员在季前赛和比赛赛季中收集的记录中获得的。
多裂肌在 L5 处的尺寸减小始终可以预测季前赛和比赛赛季的损伤。多裂肌的不对称性和腰痛与季前赛的下肢损伤显著相关，而没有首选的踢球腿则与赛季的损伤有关。多裂肌大小的季节性变化表明肌肉质量下降与损伤有关。该模型在季前赛中的敏感性和特异性分别为 60.6%和 84.9%，在比赛赛季中的敏感性和特异性分别为 91.8%和 45.8%。
开发了一种预测足球运动员下肢损伤的模型，该模型对俱乐部医务人员具有潜在的实用价值。值得注意的是，从季前赛到比赛赛季肌肉大小的变化预测了损伤。
由于多裂肌的大小可以通过训练来改变，并且与疼痛减轻和受伤发生有关，因此这些信息可以纳入当前的损伤预防计划中。
