To assess associations among commonly used self-report and clinical measures of balance in chronic TBI.
Cross-sectional analysis of balance in a convenience sample of individuals at least one year post TBI.
Activities-Specific Balance Confidence Scale (ABC) (self-reported balance impairment), Community Balance and Mobility Scale (CB&M) (clinical measure validated in TBI), and Balance Evaluation Systems Test (BESTest) (clinical measure not validated in TBI).
Fifty-nine individuals (64% male, mean age 48.2 years) ambulating independently within the home participated in testing. Pearson correlation coefficients were used to quantify the direction and magnitude of the relationships among the three balance impairment measures.
A significant positive correlation was noted between the ABC and CB&M (r = 0.42, p = 0.0008), between the ABC and BESTest (r = 0.46, p = 0.0002), and between the CB&M and BESTest (r = 0.86, p < 0.0001).
This is the first study we are aware of in the chronic moderate to severe TBI population directly comparing patient's self-reported balance impairment with clinical measures. Positive correlations were found between the self-report measure and both clinical measures. Overall, individuals with chronic TBI tend to self-report less impaired balance than clinical measures indicate. These results provide preliminary evidence to support the need for validation of the BESTest in this population.

评估慢性创伤性脑损伤（TBI）中常用的自我报告平衡测量方法与临床平衡测量方法之间的关联。
对TBI后至少一年的便利样本个体进行平衡的横断面分析。
特定活动平衡信心量表（ABC）（自我报告的平衡障碍）、社区平衡与移动量表（CB&M）（在TBI中经验证的临床测量方法）以及平衡评估系统测试（BESTest）（未在TBI中验证的临床测量方法）。
59名在家中独立行走的个体（64%为男性，平均年龄48.2岁）参与了测试。使用Pearson相关系数来量化三种平衡障碍测量方法之间关系的方向和大小。
ABC与CB&M之间存在显著正相关（r = 0.42，p = 0.0008），ABC与BESTest之间存在显著正相关（r = 0.46，p = 0.0002），CB&M与BESTest之间存在显著正相关（r = 0.86，p < 0.0001）。
这是我们所知的第一项针对慢性中度至重度TBI人群，直接比较患者自我报告的平衡障碍与临床测量方法的研究。在自我报告测量方法与两种临床测量方法之间均发现了正相关。总体而言，慢性TBI个体自我报告的平衡障碍程度往往低于临床测量结果所示。这些结果提供了初步证据，支持在该人群中对BESTest进行验证的必要性。
