“…However, symptom frequency and severity often do not correlate well with a patients' ability to perform daily activities or participate in daily life [29]. Also, environmental factors such as the construction of buildings or the characteristics of natural surroundings [5] creating disorienting visual clues [25] or the movement of large objects, disorienting lights or sounds [6,22] can contribute to the burden of disability caused by vertigo.…”

Symptom frequency and severity in vestibular disorders often do not correlate well with patients' restrictions of activities of daily living and limitations of participation. Due to the lack of appropriate patient reported outcome measures (PRO), the extent of limitations and restrictions is mostly unknown. The International Classification of Functioning, Disability and Health (ICF) is a conceptual framework and classification to evaluate all aspects of health and disability. An ICF-based measure, the Vestibular and Participation Measure (VAP), was recently proposed. Also, an ICF Core Set for vertigo, dizziness and balance disorders was developed to describe what aspects of functioning should be measured. This study protocol describes the development and cross-cultural validation of a new measure, the VAP-extended (VAP-e), based on VAP and ICF Core Set on three continents. To determine objectivity and cross-cultural validity of the VAP and to find potentially redundant items, Rasch models will be used. The VAP-e will be created by modifying or adding items from the Activities and Participation and Environmental Factors component of the ICF Core Set. Reliability, objectivity and responsiveness of the VAP-e will be tested.

ÖzetVestibüler rehabilitasyon periferik ve santral vestibüler sistem hastalıklarında kullanılan bir tedavi yöntemidir. Vestibüler rehabilitasyonun amacı insan beynindeki adaptif ve kompansatuar mekanizmaları harekete geçirmektir. Başlıca endikasyonları, vestibüler hipofonksiyon ve benign paroksismal pozisyonel vertigodur. Stabil olup henüz kompanzasyon mekanizması tamamlanmamış vestibüler sistem lezyonlarında önerilmektedir. Spesifik ve spesifik olmayan tedavi yöntemleri bulunmaktadır. Spesifik tedavi yöntemleri arasında habitüasyon, adaptasyon, substitüsyon ve otolitlerin yeniden pozisyonlandırılması gelirken, spesifik olmayan metotlar arasında endurans egzersizleri, yürüme ve denge ile ilgili spesifik kas gruplarının güçlendirilmesi gelmektedir. Vestibüler rehabilitasyonda uygulanan diğer tedavi seçenekleri vibrotaktil geri besleme, sanal gerçek-lik ve vestibüler elektriksel stimülasyondur. Vestibüler rehabilitasyon, dalgalanma gösteren vestibüler kayıplarda, devam eden labirent patolojilerinde ve yavaş progresyon gösteren bir tümör varlığında faydasızdır. Vestibüler sistem ile ilgili patolojiler vertigo, presenkop veya dengesizlik ile sonuçlanır ve ilişkili semptomlar genel olarak baş dönmesi veya sersemlik hissi şeklinde ifade edilir (1). Birçok vestibüler sistem lezyonu benign karakterdedir ve vestibüler kompanzasyon mekanizmaları ile spontan rezolüsyona girer (2).Vestibüler rehabilitasyon, insan beynindeki adaptif ve kompansatuar mekanizmaları harekete geçirmeyi hedefleyen bir tedavi yönte-midir. İlk kez Cawthorne ve Cooksey tarafından cerrahiye ya da kafa travmasına bağlı labirent yaralanması olan hastalarda kullanılmıştır (3, 4). 73

“…The idea behind this approach is that repeated exposure to visual motion can reduce the severity of disturbances caused by visual motion in certain vestibular patients (Guerraz et al, 2001; Pavlou, Bronstein, & Davies, 2013; Pavlou, Lingeswaran, Davies, Gresty, & Bronstein, 2004; Pavlou, 2010; Riecke & Schulte-pelkum, 2013). This kind of therapeutic intervention can be facilitated by using electronic screens instead of previously used mechanical devices (Pavlou, 2010; Pavlou et al, 2012, 2013; Roberts, Bronstein, & Seemungal, 2013; Vitte, Sémont, & Berthoz, 1994). …”

Effects of visual roll-motion on postural sway and the subjective visual vertical (SVV) often is studied using mechanical devices, whereas electronic displays offer cheaper and more flexible alternatives. These devices typically emit and reflect light scattered by the edges of the screen, providing Earth-fixed cues of verticality. These cues may decrease the effects of rotating stimuli, a possibility that has not been studied explicitly before in one experimental design. We exposed 16 participants to a visual dot pattern, either stationary, or rotating in roll, that was or was not surrounded by a visible Earth-fixed reference frame. To eliminate unintended visual cues, the experiment was performed in complete darkness and participants wore neutral density goggles passing only 1% of light. Postural sway was measured using a force platform. SVV measurements were obtained from a visible rod. To monitor the participants, motion sickness severity was obtained with an 11-point rating scale. Results showed that the presence of an Earth-fixed frame significantly decreased the effect of the rotating pattern on postural sway and SVV deviations. Therefore, when studying subjective verticality related effects of visual stimuli, it is imperative that all visual Earth-fixed cues are not just minimized but completely eliminated. The observation that an Earth-fixed frame significantly decreased the effect of the rotating pattern on both postural sway and the SVV points towards a common neural origin, possibly involving a neural representation of verticality. Finally, we showed that an electronic screen can yield similar effect sizes as those taken from the literature using mechanical devices.Electronic supplementary materialThe online version of this article (doi:10.3758/s13414-016-1150-3) contains supplementary material, which is available to authorized users.
