The interlimb postural comparison i.e., between the dominant leg and the non-dominant leg has been studied by numerous authors but their results are contradictory and do not lead to a consensus. Some studies showed no difference of postural balance between the dominant and the non-dominant leg whereas other studies concluded that the dominant and non-dominant leg exhibit different postural balance in healthy subjects and athletes. The aim was to analyse all these studies in order to identify the different factors that could facilitate or prevent the appearance of a postural difference between the dominant and non-dominant leg by means of a narrative review. Environmental and experimental conditions (e.g., difficulty and specificity of postural tasks; physiological state, expertise level and moment of season/period over career of subjects/athletes evaluated and nature of sport/physical activity practiced; techniques and methods used for measuring postural balance) in which postural balance is evaluated and intrinsic/individual factors (e.g., morphology, strength/power muscle, proprioception, hemispheric laterality) could influence the results. Thus, the influence of limb dominance on monopedal postural balance would probably be context-dependent. Mechanistic explanations are proposed to explain how each factor could act on the relationship between limb dominance and postural balance. However many mechanisms have not yet been explained and all the factors have not been identified, which suggests that further exploratory research is needed in order to understand this relationship.
肢体间姿势比较，即优势腿和非优势腿之间的姿势比较，已经被许多作者研究过，但他们的结果相互矛盾，没有达成共识。一些研究表明，在健康受试者和运动员中，优势腿和非优势腿的姿势平衡没有差异，而其他研究则得出结论，优势腿和非优势腿表现出不同的姿势平衡。目的是通过叙述性综述分析所有这些研究，以确定不同的因素，这些因素可以通过环境和实验条件（例如，姿势任务的难度和特异性；受试者/运动员评估时的生理状态、专业水平和赛季/周期阶段；所进行的运动/体育活动的性质；用于测量姿势平衡的技术和方法）以及内在/个体因素（例如，形态、肌肉力量/功率、本体感觉、半球侧化）促进或阻止优势腿和非优势腿之间出现姿势差异。因此，肢体优势对单足姿势平衡的影响可能是情境依赖的。提出了一些机制解释来解释每个因素如何作用于肢体优势和姿势平衡之间的关系。然而，许多机制尚未得到解释，所有的因素也尚未确定，这表明需要进一步的探索性研究来理解这种关系。
