摘要

背景和目的:本横断面研究旨在(1)建立头戴式显示器(HMD)评估慢性创伤性脑损伤(TBI)参与者姿势控制感觉统合的安全性和耐受性;(2)探讨脑外伤患者对视觉和听觉线索的反应是否与健康对照组存在差异;(3)评估体位反应、体位视觉依赖和自我报告的残疾知觉之间的关系。方法:20名健康成人和19名TBI患者完成了视觉和听觉干扰的HMD评估。头部摇摆被量化为正前方和中外侧方向的定向路径。参与者还完成了模拟病问卷(SSQ)和眩晕障碍量表(DHI)。结果:所有参与者均完成测试。从体位控制评估前到体位控制评估后,健康对照组的SSQ得分平均变化为0.8分,TBI参与者的SSQ得分平均变化为3.2分。脑外伤组的头部在两个方向上的摆动都更高,尤其是在动态视觉上。此外,声音-视觉-群体在中外侧方向上的显著相互作用表明,当声音存在时,TBI参与者对视觉扰动的反应更大。在最具挑战性的条件下,有轻度到中度头晕障碍的人几乎没有头晃,而那些有严重症状的人则更不一样。讨论和结论:对TBI患者进行HMD评估是可行的,并为该人群提供了一种基于临床的姿势视觉依赖评估。这种评估具有评估体位控制和监测TBI参与者进展的潜力。

Moving Sounds Increase Postural Visual Dependence in Adults With Chronic Traumatic Brain Injury.

Background and purpose: This cross-sectional study aimed to (1) establish the safety and tolerability of head-mounted display (HMD) assessment of sensory integration for postural control in participants with chronic traumatic brain injury (TBI); (2) investigate whether responses to visual and auditory cues differ between persons with TBI and healthy controls; and (3) evaluate the relationship between postural responses, postural visual dependence, and self-reported perception of disability.

Methods: 20 healthy adults and 19 participants with TBI completed an HMD assessment of with visual and auditory perturbations. Head sway was quantified as a directional path in the anteroposterior and mediolateral directions. Participants also completed the Simulator Sickness Questionnaire (SSQ) and the Dizziness Handicap Inventory (DHI).

Results: All participants completed testing. The average change in SSQ scores from pre to post postural control assessment was 0.8 points for healthy controls and 3.2 points for participants with TBI. Head sway in the TBI group was consistently higher in both directions, especially with dynamic visuals. In addition, a significant sound by visual by group interaction in the mediolateral direction indicates that participants with TBI responded more to the visual perturbations when sounds were present. Under the most challenging conditions, people with mild-to-moderate dizziness handicap showed little head sway, while those with severe symptoms were more variable.

Discussion and conclusions: HMD assessment of participants with TBI is feasible and provides a clinic-based assessment of postural visual dependence in this population. This assessment carries the potential to evaluate postural control and monitor progress of participants with TBI.

期刊介绍: The Journal of Neurologic Physical Therapy (JNPT) is an indexed resource for dissemination of research-based evidence related to neurologic physical therapy intervention. High standards of quality are maintained through a rigorous, double-blinded, peer-review process and adherence to standards recommended by the International Committee of Medical Journal Editors. With an international editorial board made up of preeminent researchers and clinicians, JNPT publishes articles of global relevance for examination, evaluation, prognosis, intervention, and outcomes for individuals with movement deficits due to neurologic conditions. Through systematic reviews, research articles, case studies, and clinical perspectives, JNPT promotes the integration of evidence into theory, education, research, and practice of neurologic physical therapy, spanning the continuum from pathophysiology to societal participation.
