摘要

本文提出了一种新的直立姿势建模和分析方法,该方法基于模拟人体姿势的球形倒立摆。摆在θ和ξ两个方向上振荡,从中导出了数学模型,并引入了振荡方向上的两个转矩分量。它们是使用足部压力测绘系统获取的稳定测量数据来估计的。该模型使用19名参与者的数据进行了定量研究,根据足弓指数,他们首先被分为三组。然后收集稳定数据并将其输入到模型中,以估计扭矩的分量。对分量进行了统计处理,结果表明,θ方向的分量能够抑制固有扰动。使用快速傅立叶变换对方向上的分量的频谱进行处理,结果表明该分量在分离足部畸形方面的可行性。此外,由于施加的扭矩较小,高足弓的情况往往比其他情况更稳定。将我们的模型估计的扭矩分布与经典倒立摆的扭矩分布进行了比较。在大多数情况下,我们的结果显示出显著的变化(t检验p < 0.05)。

Using a spherical inverted pendulum and statokinesigram for modeling and evaluating quiet standing posture
This paper proposes a new approach to model and analyze erect posture, based on a spherical inverted pendulum which is used to mimic the body posture. The pendulum oscillates in two directions, θ and ϕ , from which the mathematical model was derived and two torque components in oscillation directions were introduced. They are estimated using stabilometric data acquired by a foot pressure mapping system. The model was quantitatively investigated using data from 19 participants, who were first were classified into three groups, according to the foot arch-index. Stabilometric data were then collected and fed into the model to estimate the torque’s components. The components were statistically processed, and the results revealed that the components in direction θ are able to reject intrinsic perturbation. The frequency spectrum of the components in direction ϕ was processed using fast Fourier transform, and the results showed the feasibility of the component in segregating foot deformities. In addition, high-arched foot cases tended to be more stable than other cases because the exerted torque is less. The torque profiles estimated by our model were compared with the profiles derived from a classical inverted pendulum. In most cases, our results showed a significant change (t-test p < 0.05).
