Vertigo is the sensation of self-motion of the head or body when no self-motion is occurring or the sensation of distorted self-motion during an otherwise normal head movement. Representative peripheral vertigo disorders include benign paroxysmal positional vertigo, Ménière disease, and vestibular neuritis. Vestibular neuritis, also known as vestibular neuronitis, is the third most common peripheral vestibular disorder after benign paroxysmal positional vertigo and Ménière disease. The cause of vestibular neuritis remains unclear. However, a viral infection of the vestibular nerve or ischemia of the anterior vestibular artery is known to cause vestibular neuritis. In addition, recent studies on immune-mediated mechanisms as the cause of vestibular neuritis have been reported. The characteristic clinical features of vestibular neuritis are abrupt true-whirling vertigo lasting for more than 24 hours, and no presence of cochlear symptoms and other neurological symptoms and signs. To accurately diagnose vestibular neuritis, various diagnostic tests such as the head impulse test, bithermal caloric test, and vestibular-evoked myogenic potential test are conducted. Various treatments for vestibular neuritis have been reported, which are largely divided into symptomatic therapy, specific drug therapy, and vestibular rehabilitation therapy. Symptomatic therapies include generalized supportive care and administration of vestibular suppressants and antiemetics. Specific drug therapies include steroid therapy, antiviral therapy, and vasodilator therapy. Vestibular rehabilitation therapies include generalized vestibular and customized vestibular exercises.

Introduction: Vertigo is one of the common symptoms that we can see often clinically. It is hallucination to motion of oneself or surroundings. Vertigo include not only simple whirling sensation but also leaning or falling down sensation. Particularly in vestibular neuritis, the principal symptoms is dizziness and accompanied by nystagmus, gait imbalance, nausea, vomiting. Cause of vestibular neuritis is inflammatory disease such as common cold. Objective: The aim of this study was to estimate the efficacy of oriental-treatment on vestibular neuritis patient Subjects: We diagnosed one patient who had severe vertigo and gait imbalance as "dizziness retention of phlegm"(담훈) and treat orientally. Conclusion: After oriental-treatment for 15 days, walk balance was improved and no more vertigo was appeared. We could assume that in the vertigo and gait inbalance due to vestibular neuritis, the acupuncture and herbal medicine can be used.

When one sensor cannot provide information by sensory deficit or loss, the sensory information can be provided by substituting other sensors for the defected sensor. This sensory substation might be influence on the deteriorated motion perception that consists of multi-sensory information such as visual, vestibular and somatosensory information. In this study, to investigate whether the additional sensation by sensory substitution could be integrated into the motion perception, we examined the effect of substituted postural sway sensation on the directional perception of body movement. Deteriorated motion perception by the reduced plantar sensation was enhanced under sensory substitution condition that provided the body sway information as the plantar vibratory stimulus. These results imply that the additional sensation might be integrated into and improve the motion perception.

Dizziness can be classified mainly into 4 types: vertigo, disequilibrium, presyncope, and lightheadedness. Among these types, vertigo is a sensation of movement or motion due to various causes. The main causes of peripheral vertigo are benign paroxysmal positional vertigo (BPPV), acute vestibular neuritis (AVN), and Meniere's disease. BPPV is one of the most common causes of peripheral vertigo. It is characterized by brief episodes of mild to intense vertigo, which are triggered by specific changes in the position of the head. BPPV is diagnosed from the characteristic symptoms and by observing the nystagmus such as in the Dix-Hallpike test. BPPV is treated with several canalith repositioning procedures. AVN is the second most common cause of peripheral vertigo. Its key symptom is the acute onset of sustained rotatory vertigo without hearing loss. It is treated with symptomatic therapy with antihistamines, anticholinergic agents, anti-dopaminergic agents, and gamma-aminobutyric acid-enhancing agents that are used for symptoms of acute vertigo. Meniere's disease is characterized by episodic vertigo, fluctuating hearing loss, and tinnitus. It is traditionally relieved with life-style modification, a low-salt diet, and prescription of diuretics. However, diagnosis and treatment of the peripheral vertigo can be difficult without knowledge of BPPV, AVN, and Meniere's disease. This article provides information on the differential diagnosis of peripheral vertigo in BPPV, AVN, and Meniere's disease.

This study proposes a sports simulation device with various harmonics generation. The proposed system is composed of 6 degrees of freedom simulator devices and three types of sports simulation such as walking, snowboard, and jet-ski. In this research, every joint movement is designed with a crank-and-slider mechanism, which is efficient for generating continuous curvature smoothly. Contrary to the conventional spatial simulator with linear actuators, harmonics generation and its spatial combinations become the crucial issue in this research. The harmonic pattern in each joint is modelled for generating smooth curvatures that are also superposed for achieving overall motions. In addition, the targeted motions of sports simulations have different physical factors of periodic gait motion, frictionless surface, and buoyant effects, which are respectively designed by integrating three dimensional graphics information.

We performed experimental studies on the muscle activities in the lower limbs for the different movement patterns on an unstable platform. A training system for postural control using an unstable platform that we previously developed was applied for the experiments. This unstable platform provides 360 degrees of movement allowing for training of posture in various directions and provides simultaneous excitations to visual sensory, somatic sensation and vestibular organs. Compare with the stable platform, keeping body balance on the unstable platform requests more effective sensation from vision, vestibular sense and somatic sense. Especially, the somatosensory inputs from the muscle proprioceptors and muscle force are crucial. To study the muscle activities for the different movement patterns and find the best training method for improving the ability of postural control through training and improving the lower extremity muscular strength, fifteen young healthy participants went through trainings and experiments. The participants were instructed to move the center of pressure following the appointed movement pattern while standing on the unstable platform. The electromyographies of the muscles in the lower limbs were recorded and analyzed in the time and the frequency domain. Our experimental results showed the significant differences in muscle activities for the different movement patterns. Especially, the spectral energy of electromyography signals in muscle for the movement pattern in anterior-posterior direction was significantly higher than those occurred in the other patterns. The muscles in the lower leg, especially tibialis anterior and gastrocnemius were more activated compared to the others for controlling the balance of body on the unstable platform. The experimental results suggest that, through the choice of different movement pattern, the training for lower extremity strength could be performed on specific muscles in different intensity. And, the ability of postural control could be improved by the training for lower extremity strength.

낙상은 노인에서 중요한 건강문제와 직결된다. 노인의 활동력 저하와 노화로 인한 생리학적 변화는 균형과 기능적 가동성 감소를 초래하고 낙상의 주요 요인이 된다. 노년기의 신체활동은 근력유지뿐만 아니라 균형감각 같은 신경계의 기능유지를 위해서도 필요하다. 노화 되어감에 따라 활동이 줄어들고 대근의 활동보다는 소근의 활동을 중심으로 소일하는 경우가 대부분이다. 따라서 신체의 운동범위가 좁아짐에 따라 활동할 때 신체균형감각이 둔화되어 낙상을 일으키게 되고 심각한 사회적 문제를 초래하게 된다. 그러므로 노인의 낙상방지와 생활의 질적 향상을 위해 적당한 강도의 운동과 균형수행력을 향상시키는 훈련이 필요하다.
