感觉组织测试（SOT）旨在测量姿势控制的变化，以响应不可靠的视觉和/或本体感受反馈。然而，继发于仅在矢状面中的感觉线索的操纵，SOT仅能够描述在单个方向上的姿势控制。本研究的目的是描述对改良SOT的姿势反应，该改良SOT旨在同时挑战前后位和内外侧姿势控制。21名健康成年志愿者（30.6 ± 10.2岁）完成了标准前后一维（1D）SOT，以及改良的SOT，其中支持表面摇摆参考前后和内外侧姿势摇摆（二维，2D）。我们的主要分析涉及在标准一维（即，俯仰倾斜）和新颖的二维（即，横摇和俯仰倾斜）摇摆参考范例。在这里，通过计算每次试验期间压力中心（CoP）的均方根距离（RMSD）来量化姿势摇摆。我们的数据表明，2D摇摆参考条件相对于标准1D条件，在宽（η2 = 0.66）和窄（η2 = 0.78）站立条件下，产生了选择性的中外侧姿势摇摆增加，前后姿势摇摆基本上不受影响（η2 = 0.001至0.103，分别）。与1D范式（1.25至1.84倍）相比，2D范式（2.99至6.26倍）中摇摆参考条件下的内外侧姿势摇摆与相应稳定支撑表面条件下的姿势摇摆之间的比率更大（1.25至1.84倍），这与2D范式中可行的本体感受反馈的上级退化一致。与标准1D SOT方案相比，改良2D版本的SOT对中外侧姿势控制的挑战更大，这是由于其在中外侧方向上降低本体感受反馈的上级能力。鉴于这些积极的发现，未来的研究应该调查这种改良的SOT的临床效用，作为一种手段，通过它更好地表征感觉的贡献，姿势控制存在各种感觉运动病理，包括前庭功能减退。
The Sensory Organization Test (SOT) was designed to measure changes in postural control in response to unreliable visual and/or proprioceptive feedback. However, secondary to the manipulation of sensory cues in only the sagittal plane, the SOT is capable of only describing postural control in a single direction. The present study aimed to characterize postural responses to a modified SOT designed to concurrently challenge both anteroposterior and mediolateral postural control. Twenty-one healthy adult volunteers (30.6 ± 10.2 years) completed the standard anteroposterior one-dimensional (1D) SOT, in addition to a modified SOT with the support surface sway-referenced to both anteroposterior and mediolateral postural sway (two-dimensional, 2D). Our primary analysis concerned a comparison of mediolateral, as well as anteroposterior postural sway measured during the standard one-dimensional (i.e., pitch tilt) and the novel two-dimensional (i.e., roll and pitch tilt) sway-referenced paradigms. Here, postural sway was quantified by calculating the root mean square distance (RMSD) of the center of pressure (CoP) during each trial. Our data showed that the 2D sway-referenced conditions yielded a selective increase in mediolateral postural sway relative to the standard 1D conditions for both wide (η2 = 0.66) and narrow (η2 = 0.78) stance conditions, with anteroposterior postural sway being largely unaffected (η2 = 0.001 to 0.103, respectively). The ratio between mediolateral postural sway in the sway-referenced conditions and postural sway in the corresponding stable support surface conditions was greater for the 2D (2.99 to 6.26 times greater) compared to 1D paradigms (1.25 to 1.84 times greater), consistent with a superior degradation of viable proprioceptive feedback in the 2D paradigm. A modified 2D version of the SOT was shown to provide a greater challenge to mediolateral postural control relative to the standard 1D SOT protocol, putatively as a result of a superior capacity to degrade proprioceptive feedback in the mediolateral direction. Given these positive findings, future studies should investigate the clinical utility of this modified SOT as a means by which to better characterize sensory contributions to postural control in the presence of various sensorimotor pathologies, including vestibular hypofunction.
