To characterize the prevalence of, and relationship between, self-reported balance disturbance and performance-based balance impairment in the general population with concussion.
Rehabilitation hospital outpatient concussion clinic.
One hundred six individuals with concussion (49 males, mean age = 32.4; SD = 11.5 years), mean (SD) = 5 (1.8) days postinjury.
Cross-sectional observational study.
SCAT3 Symptoms Subscale, Balance Error Scoring System, modified Balance Error Scoring System, and center-of-pressure root-mean-square amplitude and velocity in eyes open and closed conditions.
The majority of participants reported balance or dizziness symptoms (54% and 63%, respectively) and demonstrated balance impairment on the Balance Error Scoring System and modified Balance Error Scoring System (66% and 58%, respectively). The prevalence of balance impairment across center-of-pressure measures varied from 32% to 48%. There was no effect of balance or dizziness symptom severity on any of the balance measures (F2,103 = 1.02; P = .44) and (F2,103 = 1.45; P = .10), respectively. There was poor agreement between self-report of balance/dizziness symptoms and identified balance impairment across all balance measures (all κ ≤ 0.26 and κ ≤ 0.20, respectively).
There was no clear relationship between the subjective experience of balance disturbance and objective measures of balance impairment in the general population. These results have implications for clinical evaluation of postconcussive deficits and determination of recovery.
描述一般人群中报告的平衡障碍的患病率，以及与基于表现的平衡损伤之间的关系，这些人群患有脑震荡。
康复医院门诊脑震荡诊所。
106 名脑震荡患者（49 名男性，平均年龄=32.4；标准差=11.5 岁），平均（标准差）=5（1.8）天。
横断面观察性研究。
SCAT3 症状子量表、平衡错误评分系统、改良平衡错误评分系统以及睁眼和闭眼条件下的中心压力均方根幅度和速度。
大多数参与者报告了平衡或头晕症状（分别为 54%和 63%），并且在平衡错误评分系统和改良平衡错误评分系统上表现出平衡损伤（分别为 66%和 58%）。中心压力测量的平衡损伤的患病率从 32%到 48%不等。平衡或头晕症状严重程度对任何平衡测量结果均无影响（F2,103 = 1.02；P =.44）和（F2,103 = 1.45；P =.10）。自我报告的平衡/头晕症状与所有平衡测量结果中确定的平衡损伤之间的一致性较差（所有κ值≤0.26 和 κ值≤0.20）。
在一般人群中，主观的平衡障碍体验与客观的平衡损伤测量之间没有明确的关系。这些结果对脑震荡后缺陷的临床评估和恢复的确定具有影响。
