Reference values of sway parameters have not been published for the Leonardo mechanograph so far. The aim of this cross-sectional study was to determine normative values on postural control measured by the force plate Leonardo Mechanograph and to analyze the influence of age and sex on balance performance. A set of standardized standing positions with eyes opened (Romberg, semi-tandem, tandem, unipedal standing) was carried out. Analysis of covariance (ANCOVA) was used to detect age-and sex-related differences in center of pressure (COP) parameters (path length, velocity, elliptical area, anterior-posterior, and medio-lateral directions). Measurements were available for 570 subjects aged 20-86 years. Statistical analysis showed a high effect of age group on postural control (partial n² between 0.1 and 0.4) with a U-shaped dependency between postural control and age for all area- and path-related COP parameters, with the largest sway in the youngest (aged 20-40) and the oldest age group (aged 60-86). For velocity of COP, a linear deterioration with increasing age was found. Medio-lateral components of COP are likely to indicate the extent of postural control. Significant sex differences were not clearly supported by current findings. Age- and sex-related normative values are a useful resource for diagnostic, research, and training.
到目前为止，尚未公布Leonardo力学描记器摇摆参数的参考值。这项横断面研究的目的是确定通过Leonardo力学描记器测力板测量的姿势控制的标准值，并分析年龄和性别对平衡能力的影响。进行了一组标准化的睁眼站立姿势（罗姆伯格姿势、半串联姿势、串联姿势、单脚站立）。采用协方差分析（ANCOVA）来检测压力中心（COP）参数（路径长度、速度、椭圆面积、前后方向和内外侧方向）的年龄和性别相关差异。对570名年龄在20至86岁之间的受试者进行了测量。统计分析表明，年龄组对姿势控制有很大影响（偏η²在0.1至0.4之间），所有与面积和路径相关的COP参数的姿势控制与年龄之间呈U形依赖关系，最年轻（20至40岁）和最年长年龄组（60至86岁）的摇摆最大。对于COP速度，发现随着年龄增长呈线性下降。COP的内外侧分量可能表明姿势控制的程度。目前的研究结果并未明确支持显著的性别差异。年龄和性别相关的标准值是诊断、研究和训练的有用资源。
