Our results suggest that this method provides a simple, inexpensive tool for assessing static postural control. Whilst it is recognised that visual input and proprioception play a central role in maintaining posture, our findings suggest that ambient sound and hearing may also have a significant influence.
Individuals with vestibular dysfunction may experience visual vertigo (VV), in which symptoms are provoked or exacerbated by excessive or disorientating visual stimuli (e.g. supermarkets). VV can significantly improve when customized vestibular rehabilitation exercises are combined with exposure to optokinetic stimuli. Virtual reality (VR), which immerses patients in realistic, visually challenging environments, has also been suggested as an adjunct to VR to improve VV symptoms. This pilot study compared the responses of sixteen patients with unilateral peripheral vestibular disorder randomly allocated to a VR regime incorporating exposure to a static (Group S) or dynamic (Group D) VR environment. Participants practiced vestibular exercises, twice weekly for four weeks, inside a static (Group S) or dynamic (Group D) virtual crowded square environment, presented in an immersive projection theatre (IPT), and received a vestibular exercise program to practice on days not attending clinic. A third Group D1 completed both the static and dynamic VR training. Treatment response was assessed with the Dynamic Gait Index and questionnaires concerning symptom triggers and psychological state. At final assessment, significant betweengroup differences were noted between Groups D (p = 0.001) and D1 (p = 0.03) compared to Group S for VV symptoms with the former two showing a significant 59.2% and 25.8% improvement respectively compared to 1.6% for the latter. Depression scores improved only for Group S (p = 0.01) while a trend towards significance was noted for Group D regarding anxiety scores (p = 0.07). Conclusion: Exposure to dynamic VR environments should be considered as a useful adjunct to vestibular rehabilitation programs for patients with peripheral vestibular disorders and VV symptoms.
The objective of the present study was to review the presentation, management, outcome and morbidity of paediatric patients presenting to a single centre with rhabdomyosarcoma of the ear and temporal region. All patients diagnosed with rhabdomyosarcoma of the ear and temporal region between 1980 and 2000 were entered into this retrospective study. Fourteen patients were identified. The median age at presentation was 4.5 years with a mean time of onset of symptoms to diagnosis of 21 weeks. In many patients, the presentation mimicked that of chronic otitis media, delaying diagnosis. Histological subtype was embryonal in 13 patients and alveolar in 1. All patients underwent multimodality treatment. The 5-year disease-free survival rate was 81%. Regional post-treatment morbidity included chronic aural discharge (6/14), facial palsy (8/14), growth disturbance (4/14) and maxillo-facial deformity occurring in four children. From the results, we conclude that these patients should usually present to an ENT surgeon who should keep the diagnosis in mind when dealing with children with chronic otitis media as early diagnosis with referral to a specialist multidisciplinary team will optimize the chance of survival. Discharge, hearing loss and aural polyp, although commonly because of chronic otitis media, should prompt urgent investigation and biopsy, particularly if associated with facial palsy, lymphadenopathy or an obvious mass.
This feasibility study suggests that the iPhone D+R Balance application deserves further investigation as a means of assessing postural sway and may provide an alternative to current dynamic posturography systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
