vertigo

What is vergence dysfunction? Vergence dysfunction refers to a condition where there are difficulties or abnormalities in the coordinated movement of the eyes to maintain single binocular vision. Binocular vision involves the simultaneous use of

A “Clinical Observations” column of VeDA’s member newsletter, “On the Level.” Discusses visual preference developed resulting from vestibular dysfunction, and provides suggestions for treating it.

Endolymphatic hydrops is a disorder of the inner ear and can affect the endolymphatic fluid of the cochlea, the vestibular apparatus, or both. Although its underlying cause and natural history are unknown, it is believed to result from abnormalities in the quantity, composition, and/or pressure of the endolymph (the fluid within the endolymphatic sac, a compartment of the inner ear).

In a normal inner ear, the endolymph is main­tained at a constant volume and with specific concentrations of sodium, potassium, chloride, and other electrolytes. This fluid bathes the sensory cells of the inner ear and allows them to function normally. In an inner ear affected by hydrops, these fluid-system controls are believed to be lost or damaged. This may cause the volume and concentration of the endolymph to fluctuate in response to changes in the body’s circulatory fluids and electrolytes.

Explains the link between the vestibular system and vision, describing the vestibulo-ocular reflex (VOR) in detail with information on evaluation, treatment, and coping strategies. Details the special considerations required for vision correction, including glasses and contact lenses.

The vestibular aqueduct is a tiny, bony canal that extends from the inner ear’s endolymphatic space toward the brain. It is shielded by one of the densest bones in the body, the temporal bone, which

CO JE BPPV? Benigní paroxyzmální polohové závratě (neboli BPPV) jsou nejčastější příčinou závratí, falešného pocitu točení.1 Benigní - neohrožuje život. Paroxysmální - přichází v náhlých, krátkých záchvatech. Polohové - vyvolávají je určité polohy hlavy nebo

Have you ever wondered if vestibular disorders and their symptoms are influenced by the environment? Recent work has demonstrated that the symptoms of common vestibular disorders may be linked with certain environmental factors, such as atmospheric pressure changes and allergies.

VeDA’s scientific articles can help you understand the causes of dizziness, how vestibular disorders are diagnosed, how your vision system is connected to your vestibular (inner ear) system, and what are the different types of vestibular disorders.

定制运动：VRT可以通过促进代偿帮助恢复。   前庭康复治疗(VRT)是一种专门的治疗形式，旨在缓解前庭疾病引起的问题，主要是眩晕和头晕，视线 不稳，和/或失衡和跌倒。根据临床评估、实验室检查和影像学检查的结果，以及患者的意见，制定个 性化的运动计划。不同的因素可以影响恢复的能力，包括活动水平、疼痛、其他医疗状况、药物和情绪 担忧。   已有证据表明，前庭康复可以有效改善许多前庭-内耳疾病的相关症状。 1, 2前庭疾病患者常出现眩晕、 头晕、视觉障碍和/或失衡等问题。这些都是康复治疗的目标。其他继发于前庭障碍的问题也可能出 现，如恶心和/或呕吐、注意力不集中和疲劳。   前庭障碍引起的症状会降低生活质量，影响从经济到社会参与等生活的各个方面，还会导致焦虑和抑郁 等情绪问题。此外，前庭障碍的后果之一是，这些症状经常导致人们采取久坐的生活方式，以避免引起 或恶化伴随运动而发生的头晕和失衡。因此，这种生活方式会导致肌肉力量和灵活性下降、关节僵硬增 加和耐力下降。康复中的治疗策略同样有益于这些继发性问题。   什么是前庭康复？   前庭康复(VR)是一种专门的治疗形式，旨在缓解由前庭疾病引起的原发性和继发性问题。它是一种以运 动为基础的方案，主要旨在减少眩晕和头晕，减少凝视不稳定，和/或减少失衡和跌倒风险，以及解决 前庭障碍引起的任何继发性损害。   对于大多数患前庭障碍的人来说，这种缺陷是永久性的，因为前庭功能的恢复量非常小。然而，前庭系 统受损后，症状会减轻，功能会因为代偿而改善。这是因为大脑学会了使用其他感官(视觉和本体感-身体感觉)来替代缺乏的前庭系统。对于许多人来说，随着时间的推移，代偿会自然发生，但对于症状没有减轻且继续难以恢复日常活动的患者，VR可以通过促进代偿来帮助恢复。3   VR的目标是采用以问题为导向的方法来促进代偿。这是通过定制练习来解决每个人的具体问题来实现 的。因此，在设计运动方案之前，需要进行全面的临床检查，以识别与前庭疾病相关的问题。根据确定 的前庭相关问题，可以规定三种主要的运动方法：1)适应，2)注视稳定，和/或3)平衡训练4   适应用于治疗由于自我运动而产生的头晕症状3 和/或由于视觉刺激而产生的症状。适应锻炼适用于检查结果显示在走动时头晕加重的患者，特别是当他们进行快速头部运动时，或者当他们改变姿势(如弯腰或抬头达到头顶)时。此外，适应的锻炼也适用于在购物中心和杂货店等视觉刺激环境中观看动作电影或电视时头晕加重的患者以及/或走过有图案的地毯和闪亮的地板时。适应锻炼的目标是通过反复接触引起患者头晕的特定动作或视觉刺激来减少头晕。这些练习的目的是为了温和地，或者最多是中度地激发患者的头晕症状。久而久之，只要有良好的依从性和毅力，头晕的强度就可以因为大脑的学习而忽略异常信号而降低。   注视稳定练习用于改善眼球运动的控制，以便在头部运动时视力可以清晰。这些练习适用于报告看不清
