在健康成年人和前庭障碍患者的感觉统合过程测试中，检查平衡康复单元（BRU）的心理测量学特性（重测信度，同时效度，结构效度）。实验横截面设计。前庭障碍门诊。参与者（N= 90）; 30例前庭疾病受试者（18至85岁）; 30例年轻健康成人（18至50岁）;和30例老年健康成人（60至85岁）。不适用因在前后（COPap）和内外（COPml）方向记录压力中心（COP）。COPap和COPml时间序列用于估计COP面积和速度。在所有感觉组织条件下，所有受试者的BRU COP面积和速度测量的组内相关系数（ICC）至少为0.76（p<0.001）。BRU和SOT之间存在显著相关性，COP面积的相关性为0.64 ~ 0.81，COP流速的相关性为0.44 ~ 0.76。与年轻对照组相比，老年对照组的BRU和SOT的COP面积和速度显著更大。年轻前庭组的COP（面积、速度）显著高于年轻对照组。使用BRU证明了感觉统合过程测试期间获得的COP测量的可靠性和有效性。未来的工作应该检查这些措施的响应时，个人与平衡障碍参与康复。
To examine the psychometric properties (test-retest reliability, concurrent validity, construct validity) of the Balance Rehabilitation Unit (BRU) during testing of sensory integration processes in healthy adults and individuals with vestibular disorders. Experimental cross-sectional design. Vestibular disorders clinic. Participants (N= 90); 30 subjects with vestibular disorders (18 to 85 years); 30 young healthy adults (18 to 50 years); and 30 older healthy adults (60 to 85 years). Not applicable. The Center of Pressure (COP) was recorded in the anteroposterior (COPap) and mediolateral (COPml) directions. The COPap and COPml time series were used to estimate the COP area andvelocity. The intra-class correlation coefficient (ICC) of the BRU COP area and velocity measures for all subjects were at least 0.76 in all sensory organization conditions (p<.001). Significant correlations were found between the BRU and SOT, ranging from 0.64 to 0.81 for COP area and from 0.44 to 0.76 for COP velocity. The older control group had significantly greater COP area and velocity compared with the younger controls for BRU and SOT. COP (area, velocity) was significantly higher for the younger vestibular group compared with the younger controls. The reliability and validity of COP measurements obtained during testing of sensory integration processes were demonstrated using the BRU. Future work should examine the responsiveness of these measures when individuals with balance disorders participate in rehabilitation.
