轻度脑外伤（mTBI）后常见眼动功能障碍、前庭功能障碍和持续症状;然而，视觉-前庭功能障碍、症状严重程度和动态移动任务之间的关系尚不清楚。23名mTBI后症状持续的个体（平均年龄55.7 ± 9.3岁），受伤后3个月至2年，与23名年龄和性别匹配的对照组进行比较。比较两组之间的眼功能缺陷[深度知觉、近点会聚、基线视力（BLVA）、感知时间]、前庭缺陷（俯仰和偏航平面的动态视力）、通过功能性步态评估（FGA）测量的动态移动性以及通过脑震荡后症状量表（PCSS）和头晕障碍量表（DHI）测量的症状。与对照组相比，mTBI参与者的FGA表现较差（p < 0.001），PCSS症状严重程度较高（p < 0.001），DHI评分较高（p < 0.001）。mTBI个体和对照组在水平转头行走（p = 0.002）、垂直头倾斜行走（p <0.001）、闭眼行走（p = 0.003）和爬楼梯（p = 0.001）过程中的FGA特定项目存在显著差异。FGA表现与脑震荡后的周数相关（r =-0.67，p < 0.001），深度知觉（r =-0.5348，p < 0.001），近点收敛（r =-0.4717，p = 0.001），基线视力（r =-0.4435，p = 0.002）;以及PCSS（r =-0.668，p < 0.001）和DHI（r =-0.811，p < 0.001）上的症状。动态平衡缺陷持续存在于慢性mTBI中，并且可以使用多方面的康复策略来解决，以解决眼功能障碍、脑震荡后症状和由于头晕导致的残疾感。
Oculomotor deficits, vestibular impairments, and persistent symptoms are common after a mild traumatic brain injury (mTBI); however, the relationship between visual-vestibular deficits, symptom severity, and dynamic mobility tasks is unclear. Twenty-three individuals (mean age 55.7 ± 9.3 years) with persistent symptoms after mTBI, who were between 3 months to 2 years post-injury were compared with 23 age and sex-matched controls. Oculomotor deficits [depth perception, near-point convergence, baseline visual acuity (BLVA), perception time], vestibular deficits (dynamic visual acuity in the pitch and yaw planes), dynamic mobility measured by the Functional Gait Assessment (FGA), and symptoms measured by the Post-Concussion Symptom Scale (PCSS) and Dizziness Handicap Inventory (DHI) were compared between groups. Participants with mTBI had poorer performance on the FGA (p < 0.001), higher symptom severity on the PCSS (p < 0.001), and higher DHI scores (p < 0.001) compared to controls. Significant differences were seen on specific items of the FGA between individuals with mTBI and controls during walking with horizontal head turns (p = 0.002), walking with vertical head tilts (p < 0.001), walking with eyes closed (p = 0.003), and stair climbing (p = 0.001). FGA performance was correlated with weeks since concussion (r = −0.67, p < 0.001), depth perception (r = −0.5348, p < 0.001), near point convergence (r = −0.4717, p = 0.001), baseline visual acuity (r = −0.4435, p = 0.002); as well as with symptoms on the PCSS (r = −0.668, p < 0.001), and DHI (r = −0.811, p < 0.001). Dynamic balance deficits persist in chronic mTBI and may be addressed using multifaceted rehabilitation strategies to address oculomotor dysfunction, post-concussion symptoms, and perception of handicap due to dizziness.
