The pathogenesis of VM is complex and involves multiple genetic and environmental factors. Recent studies have suggested that the pathogenesis of vestibular migraine may be associated with variations in the CACNA1A gene, which is an important gene target for controlling calcium ion channels. Such variations may further affect the functions of the vestibular nervous system, thereby causing a series of vestibular nervous system-related symptoms. This article will summarize the genetic association studies of vestibular migraine, vestibular function studies, and research on how to establish relevant animal models to illustrate the possible association between CACNA1A variations and the pathogenesis of VM, providing new ideas for clarifying the pathogenesis of VM.展开更多

However, to our knowledge, no objective test has been developed to quantify self-motion perception during clinical vestibular evaluation.ObjectiveThe main objective of the present study was to quantify vestibular perception during caloric vestibular stimulation using a tachometer.MethodsTwenty-two participants were divided into three groups: 1) younger healthy adults, 2) older healthy adults and 3) vestibular impaired adults. All participants performed bithermal water caloric irrigation during which slow-phase eye velocity (SPV) was measured using videonystagmography and self-motion velocity perception was assessed using a handheld tachometer (RPM).ResultsThe results revealed a significant difference in SPV between vestibular impaired ears and both healthy groups, and a significant difference in self-motion velocity perception between healthy young and vestibular impaired participants.ConclusionsThis study suggest that the SPV similarly to self-motion perception (RPM) can differentiate between vestibular impaired and young healthy participants. Future work is required to assess the influence of self-motion perception in aging.展开更多

The tenascin-R has repelling effect on pathfinding during axonal growth/regrowth, and thus inhibits neural circuit repair. By using immunohistochemical method, we studied the modification of tenascin-R expression in the superior, medial, lateral, and descending vestibular nuclei of the rat following unilateral labyrin- thectomy. On postoperative day 1, tenascin-R reaction in the perineuronal nets disappeared on the side of labyrinthectomy in the superior, lateral, medial, and rostral part of the descending vestibular nuclei. On survival day 3, the staining intensity of tenascin-R reaction in perineuronal nets recovered on the operated side of the medial vestibular nucleus, whereas it was restored by the time of postoperative day 7 in the superior, lateral and rostral part of the descending vestib- ular nuclei. The staining intensity of tenascin-R reaction remained unchanged in the caudal part of the descending vestibular nucleus bilaterally. Regional differences in the modification of tena- scin-R expression presented here may be associated with different roles of individual vestibular nuclei in the compensatory processes. The decreased expression of the tenascin-R may suggest the extracellular facilitation of plastic modifications in the vestibular neural circuit after lesion of the labyrinthine receptors.展开更多

Methods:Twenty-one healthy subjects were recruited in this study. We measured ocular VEMPs (oVEMPs) and cervical VEMPs (cVEMPs) in these subjects by air-conduction sound (ACS) stimulation. CHL was simulated later by blocking the right external auditory canal with a soundproof earplug to evaluate its impacts on VEMPs. Subjects' responses before simulated CHL served as the control, and were compared to their responses following simulated CHL. Results: oVEMPs following simulated CHL showed decreased response rate, elevated thresholds, attenuated amplitudes and prolonged N1 latencies compared with those before simulated CHL, and the differences were statistically significant. Similarly, cVEMPs following simulated CHL also showed decreased response rate, elevated thresholds and attenuated amplitudes, with prolonged P1 latencies compared with those before simulated CHL, although only differences in response rate, threshold and amplitude were significant. Conclusions:Conductive hearing loss affects the response rate and other response parameters in oVEMPs and cVEMPs.展开更多

SPSS 18.0 software was used to analyze the obtained data for mean and standard deviation.Results: In all healthy subjects mastoid-forehead galvanic vestibular stimulation produced a positive-negative biphasic EMG responses on SCM ipsilateral to the cathodal electrode. The latency of p13 was 11.7 ± 3.0 ms. The latency of n23 was 17.8 ± 3.4 ms. The amplitude of p13-n23 was147.0 ± 69.0 μV. The interaural asymmetry ratio(AR) of p13, n23 latency and the amplitude was respectively 0.12 ± 0.09, 0.08 ± 0.08 and0.16 ± 0.10.Discussions: Galvanic vestibular stimulation could elicit biphasic EMG responses from SCM via the vestibular nerve but not from the otolith organs. Galvanic stimulation together with air conducted sound(ACS) or bone conducted vibration(BCV) can elicit VEMPs and may enable the differentiation of retrolabyrinthine lesions from labyrinthine lesions in vestibular system.展开更多

While therelationship between the vestibular and visual systems has been well studied (Bronstein et al., 2015),little is known about the association of the peripheral vestibular system with neurodegenerative disorders (Cronin et al., 2017). Further, emerging research developments implicate the vestibular system asan opportunity for examining brain function beyond balance, and into other areas, such as cognition andpsychological functioning. Additionally, the bidirectional impact of psychological functioning is understudied in ARVL. Recognition of ARVL as part of a multifaceted aging process will help guide thedevelopment of integrated interventions for patients who remain at risk for decline. In this review, wewill discuss a wide variety of characteristics of the peripheral vestibular system and ARVL, how it relatesto neurodegenerative diseases, and correlations between ARVL and balance, vision, cognitive, and psychological dysfunction. We also discuss clinical implications as well as future directions for research, withan emphasis on improving care for patients with ARVL.展开更多

Vestibula...Pilot spatial disorientation is a leading factor contributing to many fatal flying accidents. Spatial orientation is the product of integrative inputs from the proprioceptive, vestibular, and visual systems. Vestibular neuritis (VN) can lead to sudden pilot incapacitation in flight. VN is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. As this test reflects the function of the superior part of the vestibular nerve only, cases of pure inferior nerve neuritis will be lost. This paper describes a fighter pilot with symptoms suggestive of VN but with normal caloric test results. Further test showed unilateral loss of vestibular evoked myogenic potential. We believe that the pilot suffered from pure inferior nerve vestibular neuritis. VEMP plays a major role in the diagnosis of inferior nerve vestibular neuritis in pilots. Aeromedical concerns are also discussed.展开更多

文摘Recent years have seen a burgeoning interest in elucidating the intricate relationship between vestibular dysfunction and sleep disorders,owing to their substantial impact on daily functioning and overall health.Despite significant advancements,the precise mechanisms underpinning this interplay remain elusive.This review aims to synthesize the current literature on the association between vestibular dysfunction and sleep disorders,focusing on potential causal mechanisms and therapeutic implications.We systematically examine various sleep disorders,including insomnia,circadian rhythm disorders,and sleep apnea,in association with specific vestibular dysfunctions,such as Meniere’s disease(MD),vestibular migraine(VM),benign paroxysmal positional vertigo(BPPV),vestibular neuritis(VN),and persistent postural perceptual dizziness(PPPD).By exploring these complex interactions,our goal is to provide a comprehensive understanding that contributes to the ongoing discourse in this field.We seek to encourage further investigations into innovative diagnostic and therapeutic strategies,ultimately aiming to improve the clinical management and enhance the quality of life for patients affected by both vestibular dysfunction and sleep disorders.

文摘Objective:To assess the effectiveness of machine learning in automating the prediction of vestibular abnormalities after cochlear implantation(CI)in patients with sensorineural hearing loss(SNHL),with the goal of developing a practical model that can accurately predict long-term vestibular function outcomes and identify associated risk factors.Methods:Clinical data,including imaging,vestibular evoked myogenic potentials(VEMPs),and auditory information,were collected from patients with sensorineural hearing loss(SNHL)before and after CI.The decision tree algorithm was employed to address missing values and screen pre-CI clinical features.Six machine learning methods were subsequently utilized to predict the relationships between the extracted features and post-CI vestibular dysfunction.The best-performing method determined the ranking of feature importance,which was regarded as risk factors for predicting symptoms and VEMPs results after CI.Results:Logistic regression models effectively predicted both post-CI vestibular dysfunction and abnormal cervical VEMP(c VEMP),with accuracies of 80%and 78%,respectively.The relative importance of the features,in descending order,was as follows:c VEMP latency,c VEMP amplitude,and residual hearing threshold.Moreover,the support vector machine(SVM)model attained an accuracy of 88%in predicting abnormal ocular VEMP(o VEMP)post-CI.For the SVM model,the feature importance ranking was as follows:o VEMP latency,o VEMP amplitude,and residual hearing threshold.Conclusions:This study successfully leverages machine learning techniques,specifically support vector machines(SVM)and logistic regression models,to predict the impact of CI on vestibular function.These predictive models provide valuable insights for presurgical planning and decision-making in CI procedures.Moreover,the findings highlight the critical risk factors associated with vestibular dysfunction,offering a robust reference for guiding vestibular rehabilitation strategies.
文摘Vestibular Migraine (VM) is a common neurological disorder characterized by recurrent episodes of vertigo and migraine symptoms. The pathogenesis of VM is complex and involves multiple genetic and environmental factors. Recent studies have suggested that the pathogenesis of vestibular migraine may be associated with variations in the CACNA1A gene, which is an important gene target for controlling calcium ion channels. Such variations may further affect the functions of the vestibular nervous system, thereby causing a series of vestibular nervous system-related symptoms. This article will summarize the genetic association studies of vestibular migraine, vestibular function studies, and research on how to establish relevant animal models to illustrate the possible association between CACNA1A variations and the pathogenesis of VM, providing new ideas for clarifying the pathogenesis of VM.

文摘Background:It has been reported that factors such as age and vestibular pathology (i.e. vestibular migraine) could impact self-motion perception during vestibular stimulation. However, to our knowledge, no objective test has been developed to quantify self-motion perception during clinical vestibular evaluation.ObjectiveThe main objective of the present study was to quantify vestibular perception during caloric vestibular stimulation using a tachometer.MethodsTwenty-two participants were divided into three groups: 1) younger healthy adults, 2) older healthy adults and 3) vestibular impaired adults. All participants performed bithermal water caloric irrigation during which slow-phase eye velocity (SPV) was measured using videonystagmography and self-motion velocity perception was assessed using a handheld tachometer (RPM).ResultsThe results revealed a significant difference in SPV between vestibular impaired ears and both healthy groups, and a significant difference in self-motion velocity perception between healthy young and vestibular impaired participants.ConclusionsThis study suggest that the SPV similarly to self-motion perception (RPM) can differentiate between vestibular impaired and young healthy participants. Future work is required to assess the influence of self-motion perception in aging.
文摘Objective:To analyze the necessity and effectiveness of vestibular rehabilitation training instruction in the treatment of sudden deafness accompanied by vertigo.Methods:Sixty medical staff who learned the treatment methods for sudden deafness accompanied by vertigo(vestibular rehabilitation training)from January 2024 to February 2025 were selected as the research subjects.They were divided into two groups according to the time of study:the control group,who participated in the training teaching first,and the observation group,who participated later.Each group had 30 people.The control group received conventional training,while the observation group underwent continuous quality improvement.The effects and assessment results of different teaching methods were compared.Results:The theoretical and practical assessment scores of medical staff in the observation group were higher than those in the control group(p<0.05);the satisfaction of medical staff in the observation group with the teaching mode was higher than that in the control group(p<0.05).Conclusion:Vestibular rehabilitation training has significant effects on sudden deafness accompanied by vertigo.Training medical staff not only enhances their understanding of training methods but also enables them to provide specialized guidance to patients,improving their vertigo condition.

文摘Background:Vestibular migraine(VM)is a common disorder characterized by recurrent dizziness or vertigo,often aggravated by cold exposure.This study aimed to identify differentially expressed circular RNAs(circRNAs)in cold-region VM and explore the underlying molecular mechanisms.Methods:Peripheral blood samples from long-term residents of Heilongjiang Province profiled by circRNA microarray,and differentially expressed circRNAs were validated by quantitative reverse transcription polymerase chain reaction(qRT-PCR).A competing endogenous RNA(ceRNA)network and enriched pathways were inferred by bioinformatics.A VM-like mouse model was established using nitroglycerin(NTG)and kainic acid(KA)and confirmed by behavioral testing and western blot.The hsa_circ_0003201/miR-31-5p/triggering receptor expressed on myeloid cells 2(TREM2)axis and related pathways were examined in clinical samples and in the trigeminal nucleus caudalis(TNC)and vestibular nuclei(VN)of mice using qRT-PCR,enzyme-linked immunosorbent assay(ELISA),and western blot.CircRNA microarray profiling also compared expression patterns between VM and migraine patients.Results:Hsa_circ_0003201 was significantly upregulated in cold-region VM patients.Bioinformatic analyses revealed that hsa_circ_0003201 may regulate the miR-31-5p/TREM2 axis and be associated with phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)signaling,pyruvate metabolism,and transient receptor potential(TRP)pathways.Clinical validation confirmed increased hsa_circ_0003201 and TREM2 and decreased miR-31-5p.VM-like mice exhibited central sensitization and vestibular dysfunction,with increased TREM2,decreased miR-31-5p,and PI3K/AKT activation in the TNC and VN.Comparative circRNA analysis between VM and migraine patients indicated distinct expression patterns.Conclusion:Hsa_circ_0003201 shows potential as a diagnostic biomarker for cold-region VM,and the hsa_circ_0003201/miR-31-5p/TREM2 axis may contribute to pathogenesis through PI3K/AKT signaling,pyruvate metabolism,and TRP-related pathways.
文摘The ears are air-filled structures that are directly impacted during blast exposure.In addition to hearing loss and tinnitus,blast victims often complain of vertigo,dizziness and unsteady posture,suggesting that blast exposure induces damage to the vestibular end organs in the inner ear.However,the underlying mechanisms remain to be elucidated.In this report,single vestibular afferent activity and the vestibuloocular reflex(VOR)were investigated before and after exposure to blast shock waves(~20 PSI)delivered into the left external ear canals of anesthetized rats.Single vestibular afferent activity was recorded from the superior branch of the left vestibular nerves of the blast-treated and control rats one day after blast exposure.Blast exposure reduced the spontaneous discharge rates of the otolith and canal afferents.Blast exposure also reduced the sensitivity of irregular canal afferents to sinusoidal head rotation at 0.5e2Hz.Blast exposure,however,resulted in few changes in the VOR responses to sinusoidal head rotation and translation.To the best of our knowledge,this is the first study that reports blast exposure-induced damage to vestibular afferents in an animal model.These results provide insights that may be helpful in developing biomarkers for early diagnosis of blast-induced vestibular deficits in military and civilian populations.

文摘We have previously found that unilateral labyrinthectomy is accompanied by modification of hyaluronan and chondroitin sulfate proteoglycan staining in the lateral vestibular nucleus of rats and the time course of subsequent reorganization of extracellular matrix assembly correlates to the restoration of impaired vestibular function. The tenascin-R has repelling effect on pathfinding during axonal growth/regrowth, and thus inhibits neural circuit repair. By using immunohistochemical method, we studied the modification of tenascin-R expression in the superior, medial, lateral, and descending vestibular nuclei of the rat following unilateral labyrin- thectomy. On postoperative day 1, tenascin-R reaction in the perineuronal nets disappeared on the side of labyrinthectomy in the superior, lateral, medial, and rostral part of the descending vestibular nuclei. On survival day 3, the staining intensity of tenascin-R reaction in perineuronal nets recovered on the operated side of the medial vestibular nucleus, whereas it was restored by the time of postoperative day 7 in the superior, lateral and rostral part of the descending vestib- ular nuclei. The staining intensity of tenascin-R reaction remained unchanged in the caudal part of the descending vestibular nucleus bilaterally. Regional differences in the modification of tena- scin-R expression presented here may be associated with different roles of individual vestibular nuclei in the compensatory processes. The decreased expression of the tenascin-R may suggest the extracellular facilitation of plastic modifications in the vestibular neural circuit after lesion of the labyrinthine receptors.

文摘Objective:To investigate the effects of conductive hearing loss (CHL) on vestibular evoked myogenic potentials (VEMPs) using a simulated CHL model, and to provide the basis for future studies. Methods:Twenty-one healthy subjects were recruited in this study. We measured ocular VEMPs (oVEMPs) and cervical VEMPs (cVEMPs) in these subjects by air-conduction sound (ACS) stimulation. CHL was simulated later by blocking the right external auditory canal with a soundproof earplug to evaluate its impacts on VEMPs. Subjects' responses before simulated CHL served as the control, and were compared to their responses following simulated CHL. Results: oVEMPs following simulated CHL showed decreased response rate, elevated thresholds, attenuated amplitudes and prolonged N1 latencies compared with those before simulated CHL, and the differences were statistically significant. Similarly, cVEMPs following simulated CHL also showed decreased response rate, elevated thresholds and attenuated amplitudes, with prolonged P1 latencies compared with those before simulated CHL, although only differences in response rate, threshold and amplitude were significant. Conclusions:Conductive hearing loss affects the response rate and other response parameters in oVEMPs and cVEMPs.
文摘Vestibular schwannomas(VS)are benign tumors of the vestibular nerve.The common first symptoms are hearing loss and tinnitus,followed by imbalance,vertigo,and facial nerve involvement.The subjective symptoms of VS patients are not consistent with the severity of vestibular lesions and the results of vestibular tests,which often interfere with clinicians’diagnoses.Thus,the main screening and diagnostic methods for VS are audiometry and magnetic resonance imaging(MRI),ignoring the evaluation of vestibular function at the source of pathological lesions.With the development and improvement of vestibular evaluation technology and its wide application in the clinic,modern vestibular examination technology can reflect the severity and frequency of vestibular lesions and compensation from multiple perspectives,providing an objective basis for the diagnosis and treatment of vestibular diseases.In this report,we review the results and characteristics of vestibular tests in VS patients and further clarify the clinical value of vestibular function assessment in the diagnosis and treatment of VS.

文摘Objectives: The aim of our study is to examine vestibular-evoked myogenic potentials(VEMPs) elicited by the galvanic vestibular stimulation in the sternocleidomastoid muscle(SCM) in healthy subjects for clinical applications of auditory neuropathy or vestibular neuropathy in the future.Methods: We enrolled sixteen healthy subjects to record the average responses of SCM to galvanic vestibular stimulation(GVS) [current 3 mA;duration 1 ms] by electromyography(EMG). SPSS 18.0 software was used to analyze the obtained data for mean and standard deviation.Results: In all healthy subjects mastoid-forehead galvanic vestibular stimulation produced a positive-negative biphasic EMG responses on SCM ipsilateral to the cathodal electrode. The latency of p13 was 11.7 ± 3.0 ms. The latency of n23 was 17.8 ± 3.4 ms. The amplitude of p13-n23 was147.0 ± 69.0 μV. The interaural asymmetry ratio(AR) of p13, n23 latency and the amplitude was respectively 0.12 ± 0.09, 0.08 ± 0.08 and0.16 ± 0.10.Discussions: Galvanic vestibular stimulation could elicit biphasic EMG responses from SCM via the vestibular nerve but not from the otolith organs. Galvanic stimulation together with air conducted sound(ACS) or bone conducted vibration(BCV) can elicit VEMPs and may enable the differentiation of retrolabyrinthine lesions from labyrinthine lesions in vestibular system.
文摘Objective:Saccades accompanied by normal gain in video head impulse tests(vHIT)are often observed in patients with vestibular migraine(VM).However,they are not considered as an independent indicator,reducing their utility in diagnosing VM.To better understand clinical features of VM,it is necessary to understand raw saccades data.Methods:Fourteen patients with confirmed VM,45 patients with probable VM(p-VM)and 14 agematched healthy volunteers were included in this study.Clinical findings related to spontaneous nystagmus(SN),positional nystagmus(PN),head-shaking nystagmus(HSN),caloric test and vHIT were recorded.Raw saccades data were exported and numbered by their sequences,and their features analyzed.Results:VM patients showed no SN,PN or HSN,and less than half of them showed unilateral weakness(UW)on caloric test.The first saccades from lateral semicircular canal stimulation were the most predominant for both left and right sides.Neither velocity nor time parameters were significantly different when compared between the two sides.Most VM patients(86%)exhibited small saccades,around 35%of the head peak velocity,with a latency of 200e400 ms.Characteristics of saccades were similar in patients with p-VM.Only four normal subjects showed saccades,all unilateral and seemingly random.Conclusions:Small saccades involving bilateral semicircular canals with a scattered distribution pattern are common in patients with VM and p-VM.
文摘Given the interdependence of multiple factors in age-related vestibular loss (e.g., balance, vision,cognition), it is important to examine the individual contributions of these factors with ARVL. While therelationship between the vestibular and visual systems has been well studied (Bronstein et al., 2015),little is known about the association of the peripheral vestibular system with neurodegenerative disorders (Cronin et al., 2017). Further, emerging research developments implicate the vestibular system asan opportunity for examining brain function beyond balance, and into other areas, such as cognition andpsychological functioning. Additionally, the bidirectional impact of psychological functioning is understudied in ARVL. Recognition of ARVL as part of a multifaceted aging process will help guide thedevelopment of integrated interventions for patients who remain at risk for decline. In this review, wewill discuss a wide variety of characteristics of the peripheral vestibular system and ARVL, how it relatesto neurodegenerative diseases, and correlations between ARVL and balance, vision, cognitive, and psychological dysfunction. We also discuss clinical implications as well as future directions for research, withan emphasis on improving care for patients with ARVL.

文摘Damage to the vestibular sense organs evokes static and dynamic deficits in the eye movements,posture and vegetative functions.After a shorter or longer period of time,the vestibular function is partially or completely restored via a series of processes such as modification in the efficacy of synaptic inputs.As the plasticity of adult central nervous system is associated with the alteration of extracellular matrix,including its condensed form,the perineuronal net,we studied the changes of brevican expression in the perineuronal nets of the superior vestibular nucleus after unilateral labyrinth lesion.Our results demonstrated that the unilateral labyrinth lesion and subsequent compensation are accompanied by the changing of brevican staining pattern in the perineuronal nets of superior vestibular nucleus of the rat.The reduction of brevican in the perineuronal nets of superior vestibular nucleus may contribute to the vestibular plasticity by suspending the non-permissive role of brevican in the restoration of perineuronal net assembly.After a transitory decrease,the brevican expression restored to the control level parallel to the partial restoration of impaired vestibular function.The bilateral changing in the brevican expression supports the involvement of commissural vestibular fibers in the vestibular compensation.All experimental procedures were approved by the 'University of Debrecen–Committee of Animal Welfare'(approval No.6/2017/DEMAB) and the 'Scientific Ethics Committee of Animal Experimentation'(approval No.HB/06/éLB/2270-10/2017;approved on June 6,2017).

文摘BACKGROUND Numerous studies have found that patients experiencing sudden sensorineural hearing loss(SSHL),with or without accompanying vertigo,often show impaired vestibular function.However,there is a dearth of studies analyzing vestibularevoked myogenic potentials(VEMPs)in SSHL patients across various age groups.AIM To investigate vestibular condition in SSHL patients across various age demographics.METHODS Clinical data of 84 SSHL patients were investigated retrospectively.Audiometry,cervical vestibular evoked myogenic potentials(c-VEMPs),and ocular vestibular evoked myogenic potentials(o-VEMPs)were conducted on these patients.Parameters assessed included the latencies of P1 and N1 waves,as well as the amplitudes of P1–N1 waves.Moreover,the study evaluated the influence of factors such as sex,affected side,configuration of hearing loss,and presence of accompanying vertigo.RESULTS Among the 84 SSHL patients,no significant differences were observed among the three groups in terms of gender,affected side,and the presence or absence of vertigo.Group II(aged 41–60 years)had the highest number of SSHL cases.The rates of absent o-VEMPs in the affected ears were 20.83%,31.58%,and 22.72%for the three age groups,respectively,with no statistically significant difference among them.The rates of absent c-VEMPs in the affected ears were 8.3%,34.21%,and 18.18%for the three age groups,respectively,with significant differences.In the unaffected ears,there were differences observed in the extraction rates of o-VEMPs in the unaffected ears among the age groups.In the three age groups,no significant differences were noted in the three age groups in the latencies of P1 and N1 waves or in the amplitude of N1–P1 waves for c-VEMPs and o-VEMPs,either on the affected side or on the unaffected side,across the three age groups.CONCLUSION The extraction rate of VEMPs is more valuable than parameters.Regardless of the presence of vertigo,vestibular organs are involved in SSHL.Notably,SSHL patients aged 41–60 appear more susceptible to damage to the inferior vestibular nerve and saccule.

文摘Objective Patients suffered a lot from decompensated vestibular vertigo.Pharmacotherapy and vestibular rehabilitation training have been proven to be effective in prompting vestibular compensation.Routine rehabilitation training is faced with the challenges of patients’compliance,completion,the average recuperation time and so on.This study is aimed to investigate advantages of short-term personalized vestibular rehabihitation at home guided by professional therapist.Methods A short-term personalized vestibular rehabilitation program(ST-PVR)was designed for patients with decompensated vestibular vertigo in this study.Results Patients experiencing the ST-PVR program showed significant improvement of Self-Rating Anxiety Scale(SAS),Dizziness Handicap Inventory(DHI),Activities-Specific Balance Confidence Scale(ABC)scores by the second follow-up(at 2nd week after treatment,P<0.05).However-improvement in the medication group occurred slightly later,DHI for 1 month and SAS for 2 months after treatment(P<0.05).Also,the improvement in the onset time of unilateral weakness(UW)at 2nd week after treatment in the personalized vestibular rehabilitation(PVR)group was faster than that in the medication group.Conclusion In general,the short-term PVR program showed great advantages by prompting vestibular compensation quickly and putting forward future direction for clinical treatment on decompensated vestibular vertigo.

文摘Objective Auditory neuropathy(AN)is a unique pattern of hearing loss with preservation of hair cell function.The condition is characterized by the presence of otoacoustic emissions(OAE)or cochlear microphonic(CM)responses with severe abnormalities of the auditory brainstem response(ABR).The vestibular branches of the VIII cranial nerve and the structures innervated by it can also be affected.However,the precise lesion sites in the vestibular system are not well characterized in patients with AN.Methods The air-conducted sound(ACS)vestibular-evoked myogenic potentials(VEMPs)and galvanic vestibular stimuli(GVS)-VEMPs were examined in 14 patients with AN.Results On examination of VEMPs(n=14,28 ears),the absent rates of ACS-cervical VEMP(cVEMP),ACS-ocular VEMP(oVEMP),GVS-cVEMP,GVS-oVEMP and caloric test were 92.9%(26/28),85.7%(24/28),67.9%(19/28),53.6%(15/28),and 61.5%(8/13),respectively.Impaired functions of the saccule,inferior vestibular nerve,utricle,superior vestibular nerve,and horizontal semicircular canal were found in 25.0%(7/28),67.9%(19/28),32.1%(9/28),53.6%(15/28)and 61.5%(8/13)patients,respectively.On comparing the elicited VEMPs parameters of AN patients with those of normal controls,both ACS-VEMPs and GVS-VEMPs showed abnormal results in AN patients(such as,lower presence rates,elevated thresholds,prolonged latencies,and decreased amplitudes).Conclusion The study suggested that patients with AN often have concomitant vestibular disorders.Retro-labyrinthine lesions were more frequently observed in this study.GVS-VEMPs combined with ACS-VEMPs may help identify the lesion sites and facilitate detection of areas of vestibular dysfunction in these patients.

文摘Pilot spatial disorientation is a leading factor contributing to many fatal flying accidents. Spatial orientation is the product of integrative inputs from the proprioceptive, vestibular, and visual systems. Vestibular neuritis (VN) can lead to sudden pilot incapacitation in flight. VN is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. As this test reflects the function of the superior part of the vestibular nerve only, cases of pure inferior nerve neuritis will be lost. This paper describes a fighter pilot with symptoms suggestive of VN but with normal caloric test results. Further test showed unilateral loss of vestibular evoked myogenic potential. We believe that the pilot suffered from pure inferior nerve vestibular neuritis. VEMP plays a major role in the diagnosis of inferior nerve vestibular neuritis in pilots. Aeromedical concerns are also discussed.
文摘Unilateral vestibular dysfunction is a one-sided impairment of vestibular function in one ear.Incorporating health education in treatment and rehabilitation plans can improve vestibular function,keep negative emotions at bay,and reduce the extent of the condition.This letter investigates the impact of the informationmotivation-behavioral skills model as a medium for health education on patient outcomes.While offering encouraging observations,there are certain limitations,such as the study’s retrospective design,small sample size,use of subjective measures,and lack of longer follow-ups that challenge the cogency of the study.The study is a step toward transforming vestibular dysfunction treatment through health education.
