To establish the clinical utility of the PROPRIO 5000 as a balance assessment device by establishing convergent validity with the NeuroCom sensory organization test (SOT).

Young adults (N=40; 21.1+/-1.4y).

Performance on each of the 6 NeuroCom SOT testing conditions and PROPRIO 5000 dynamic motion analysis score.
Correlational analyses between output variables yielded significant relationships between the dynamic motion analysis score from the 0 to 10 second (r=-.38), 10 to 20 second (r=-.34), and 20 to 30 second (r=-.35) intervals and the SOT composite balance score.
The initial stages of the PROPRIO 5000 and the NeuroCom SOT battery may evaluate similar aspects of postural control. However, as the magnitude of PROPRIO perturbations increased, the relationship between the devices diverged and the complete PROPRIO assessment is not thought to pair with the SOT assessment. Differences between the 2 devices may be associated with varying degrees of test difficulty and the necessary postural control strategies involved in responding to continual balance perturbations (PROPRIO 5000) or to different sensory inputs (SOT).
通过与NeuroCom感觉统合测试（SOT）建立收敛效度，确立PROPRIO 5000作为平衡评估设备的临床实用性。

6种NeuroCom SOT测试条件下的每项表现以及PROPRIO 5000动态运动分析得分。
输出变量之间的相关性分析显示，0至10秒（r = -0.38）、10至20秒（r = -0.34）和20至30秒（r = -0.35）时间段的动态运动分析得分与SOT综合平衡得分之间存在显著关系。
PROPRIO 5000和NeuroCom SOT测试组的初始阶段可能评估姿势控制的相似方面。然而，随着PROPRIO扰动幅度的增加，两种设备之间的关系出现分歧，完整的PROPRIO评估被认为与SOT评估不匹配。两种设备之间的差异可能与不同程度的测试难度以及应对持续平衡扰动（PROPRIO 5000）或不同感觉输入（SOT）所涉及的必要姿势控制策略有关。
