The subjects were divided into 7 ten-year age groups, from the 20 s to the 70 s, and a group of over 80. As a draft reference value, we thought that it might be reasonable to use the mean ±2×standard deviation and the 95 th percentile/5 th percentile together. In this analysis, mixed gender data were used, as, based on the results of statistical analysis, we considered that the reference value could be used as a standard value for both men and women. 原 著","PeriodicalId":11781,"journal":{"name":"Equilibrium Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69878234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Out of a total of 351 patients with Meniere’s disease who performed aerobic exercises for 6 months or longer who were enrolled, 338 showed improvement of one or more symptoms: disappearance of vertigo in 97.6% of cases; complete resolution of ear fullness in 60.1% of cases; improvement of hearing impairment in 38.5% of cases; complete resolution or marked decrease of tinnitus in 29.6% of cases. On the other hand, complete recovery of hearing was noted in 29.5% of the 78 patients with low-tone loss, 12.5% of the 96 patients with high-tone loss, and only 4.1% of the 170 patients with hearing loss across all frequencies. More than half of the patients with high-tone hearing loss and hearing loss across all frequencies failed to show any change in the degree of hearing loss. Considering the findings of temporal bone pathology, it seems probable that the Reissner’s membrane, being ballooned and highly distended by endolymphatic hydrops, disturbs conduction of low-frequency waves by the perilymph, and the membrane, once it loses tension, is not resonant with either high-frequency waves or indeed waves of any frequency. Although aerobic exercise is effective to cure hydrops and improve membranous tension by activating homeostasis, its effect worsens with decreasing membranous tension. 原 著","PeriodicalId":11781,"journal":{"name":"Equilibrium Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47849271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, a clinical study, in which psychologists conducted structured interviews with neuro-otology outpatients, reported that nearly half of the patients needed psychological help. In addition, although a relationship between chronic vertigo (dizziness) symptoms and anxiety has been previously reported, a study of patients with Meniere’s disease or lightheadedness reported a complication of generalized anxiety disorder and depression. It has also been reported that patients with anxiety are at high risk of developing benign paroxysmal positional vertigo. The symptoms of chronic vertigo cannot be explained only by organic abnormalities; psychological Objective: Onset of psychogenic vertigo/dizziness is affected by psychosocial factors. Somatosensory amplification is one of the psychological factors associated with functional physical symptoms, but its relationship to psychogenic vertigo remains unclear. We investigated the relationship between the frequency of vertigo episodes and somatosensory amplification in patients with psychogenic vertigo. Methods: Participants were individuals aged 20 to 79 years complaining of psychogenic vertigo. They were referred by otolaryngologists to the department of psychosomatic medicine of a university hospital in Japan. The participants’ physical and mental conditions were evaluated using the Vertigo Symptom Scale-Short Form (VSS-sf), Somatosensory Amplification Scale (SSAS), and Hospital Anxiety and Depression Scale (HADS). Multiple linear regression analysis, with VSS-sf as the independent variable, was used to assess the associations. Results: Of the 41 participants, 35 (12 males and 23 females) were included in the analysis. The VSS-sf scores showed positive correlations with the scores for the anxiety scale of the HADS and SSAS. Linear multiple regression analysis identified the VSS-sf scores as being positively associated with the scores on the SSAS (p<0.01) and negatively associated with age (p< 0.05). Conclusion: Our findings suggest that in patients with psychogenic vertigo, the vertigo episodes occur more frequently as somatosensory amplification increases, however, the frequency might decrease with age. 原 著","PeriodicalId":11781,"journal":{"name":"Equilibrium Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46300414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, I would like to describe the etiology of migraine and Meniere’s disease. In Japan, migraine is reported to occur at a prevalence of 3.6 % in men and 12.9% in women, while Meniere’s disease is reported to occur at a prevalence of approximately 2―30 cases per 1,000,000 inhabitants. In otorhinolaryngologic? outpatient practice, Meniere’s disease and vestibular migraine are reported to account for about 8%―10% of patients. There are no objective tools yet to clearly diagnose either vestibular migraine or Meniere’s disease. Recently, the habituation of middle latency response was reported as a potential objective evaluation tool for the diagnosis of vestibular migraine. Further study is required to identify objective tools for the diagnosis of vestibular migraine and Meniere’s disease. パネルディスカッション「メニエール病と前庭性片頭痛:その類似点と相違点,関係性」","PeriodicalId":11781,"journal":{"name":"Equilibrium Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42368085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maintenance of equilibrium requires proper functioning of these systems. Vestibular rehabilitation is a form of physical therapy for disorders of the vestibular system. A practice guideline on vestibular rehabilitation for peripheral vestibular hypofunction was published by the American Physical Therapy Association in 2016. The rate of improvement is lower in cases of bilateral vestibulopathy as compared to those of unilateral vestibulopathy. There have been no reports of adequate functional recovery in cases of bilateral vestibulopathy. Vestibular rehabilitation includes gaze stability exercises, habituation exercises, substitution exercises, and balance training. Exercises tailored to the individual and performed under supervision are more effective than those performed alone at home. Vestibular rehabilitation tends to be monotonous in its approach, and it often takes long before improvement begins to be noted. This usually results in patients dropping out of the protocol. In recent years, there has been an increasing number of reports on vestibular rehabilitation using virtual reality. Virtual reality involves the use of screens and head-mounted displays. It has been found to lead to improvement of the vestibuloocular reflex, postural control, dizziness handicap inventory, and quality of life. Using virtual reality games for vestibular rehabilitation may lead to patients enjoying and immersing themselves more in the rehabilitation process. It may improve their motivation, and ultimately lead them to continue and help them persevere with vestibular rehabilitation. In this paper, we discuss vestibular rehabilitation, especially for patients with bilateral vestibulopathy, and vestibular rehabilitation using virtual reality. シンポジウム「Bilateral vestibulopathy: How to treat and manage?」","PeriodicalId":11781,"journal":{"name":"Equilibrium Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47996890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
