To investigate the incidence of visual perceptual impairments in a sample of patients with traumatic brain injury (TBI) using the Occupational Therapy Adult Perceptual Screening Test (OT-APST), compare incidence rates to a normative sample and explore the relationship between the presence of visual perceptual impairment and the severity of cognitive and functional impairment following TBI.
Cohort study using a convenience sample of patients with TBI and a normative sample.
Thirty-one patients with severe TBI and 195 healthy people were compared on the OT-APST and measures of cognition and function.
The most common impairments in the TBI sample were unilateral neglect (45.2%) and impairments of body scheme (25.8%) and constructional skills (25.8%). Significantly higher incidences of agnosia, apraxia, unilateral neglect and impairments in body scheme and constructional skills were found in the TBI sample compared to the normative sample. No significant relationship was found between the presence of visual perceptual impairments and the level of cognitive and functional impairment after TBI.
Visual perceptual changes are evident in patients with severe TBI when compared to a normative sample. Routine use of a screening tool such as the OT-APST may help identify visual perceptual impairments in these patients and the need for more detailed assessment.
使用成人职业疗法感知筛查测试（OT - APST），调查创伤性脑损伤（TBI）患者样本中视觉感知障碍的发生率，将发生率与正常样本进行比较，并探讨TBI后视觉感知障碍的存在与认知和功能障碍严重程度之间的关系。
采用TBI患者便利样本和正常样本的队列研究。
对31例重度TBI患者和195名健康人进行OT - APST以及认知和功能测量的比较。
TBI样本中最常见的障碍是单侧忽视（45.2%）、身体图式障碍（25.8%）和构图技能障碍（25.8%）。与正常样本相比，TBI样本中失认症、失用症、单侧忽视以及身体图式和构图技能障碍的发生率显著更高。TBI后视觉感知障碍的存在与认知和功能障碍水平之间未发现显著关系。
与正常样本相比，重度TBI患者存在明显的视觉感知变化。常规使用诸如OT - APST之类的筛查工具可能有助于识别这些患者的视觉感知障碍以及进行更详细评估的必要性。
