Introduction The advent of the video head impulse test (vHIT) enables the study of each one of the six semicircular canals. In the present study, certain patients present disorders related only to the vertical semicircular canals, and they were carefully evaluated. Objective To investigate vestibular disorders limited to the vertical semicircular canals. Methods In total, 9,891 patients were submitted to the vHIT in our clinic; 26 (2.63%) of them, 11 men and 15 women, showed reduced vestibulo-ocular reflex (VOR) limited to the vertical canals. All of these patients had vestibular symptoms. Results These patients presented different disorders of the vestibular system, and ten of them presented vestibular neuritis. Conclusion Now, vestibular disorders limited the vertical canals can be evaluated through the vHIT. These disorders, however, may relate do different labyrinthine diseases. [ABSTRACT FROM AUTHOR]

Objective: This study examines how psychological aspects of vestibular disorders are currently addressed highlighting any national variation. Method: An online survey was completed by 101 UK healthcare professionals treating vestibular disorders. The survey covered service configurations, attitudes towards psychological aspects and current clinical practice. Results: Ninety-six per cent of respondents thought there was a psychological component to vestibular disorders. There was a discrepancy between perceived importance of addressing psychological aspects and low confidence to undertake this. Those with more experience felt more confident addressing psychological aspects. History taking and questionnaires containing one or two psychological items were the most common assessment approaches. Discussing symptoms and signposting were the most frequent management approaches. Qualitative responses highlighted the interdependence of psychological and vestibular disorders which require timely intervention. Barriers included limited referral pathways, resources and interdisciplinary expertise. Conclusion: Although psychological distress is frequently identified, suitable psychological treatment is not routinely offered in the UK. [ABSTRACT FROM AUTHOR]

Objectives: To analyse the effectiveness of optokinetic stimulation (OKS) for improving symptoms and function in patients with vestibular and balance disorders. Methods: PubMed (MEDLINE), SCOPUS, Web of Science (WOS), CINAHL Complete, and PEDro databases were searched to identify randomized controlled trials (RCTs) that included patients with vestibular and balance disorders and compared the effects of OKS versus other interventions or no intervention on subjective or objective functional outcomes. Data were analysed by the standardized mean difference (SMD) and its 95% confidence interval. Results: A total of 10 studies were selected including 468 patients, 177 of whom received OKS. There were no significant differences in scores on the Dizziness Handicap Inventory (DHI) (SMD = 0.02; 95% CI − 0.18 to 0.23; p = 0.83) or the visual analogue scale (VAS) for vertigo (SMD = 0.16; 95% CI − 1.25 to 1.58; p = 0.82). However, there were statistically significant differences in the timed up and go (TUG) test, with a large effect (SMD = − 1.13; 95% CI -2 to − 0.28; p = 0.009), and in the sensory organization test (SOT), with a medium effect (SMD = − 0.7; 95% CI − 1.21 to − 0.19; p = 0.007). Subgroup analysis showed significant effects of OKS on VAS (p = 0.017), TUG (p = 0.009) and SOT (p = 0.001) only in patients with balance disorders without vestibular disease (p > 0.05). Conclusions: OKS may improve dizziness intensity measured with VAS or dynamic balance measured whit TUG and SOT in patients with balance disorders not due to vestibular disease. The quality of the evidence was low or very low due to the small number of included studies. PROSPERO Registry number: CRD42023445024. [ABSTRACT FROM AUTHOR]

Introduction The Head Shake Sensory Organization Test (HS-SOT) assesses postural stability while the head is moving and may also identify deficits in attention associated with the dual task conditions of moving the head at a specified speed while maintaining balance. Normative values for the HS-SOT have not been established in a healthy military population or other highly trained populations such as athletes. Establishing normative values in a military population will enable clinicians to compare the scores of patients with medical conditions that affect postural stability and sensory integration such as concussion or traumatic brain injury, vestibular dysfunction, or migraine to those of a healthy population to determine a need for intervention and for return to duty considerations. The purposes of this cross-sectional study were to establish normative values for the HS-SOT within the military population, to determine whether HS-SOT scores differed between men and women or among age groups, and to determine whether HS-SOT scores differed from scores on similar conditions of the Sensory Organization Test (SOT). Materials and Methods Active duty service members (n  = 237, 54 female) at Joint Base Lewis-McChord, Washington, Fort Campbell, Kentucky, and the National Capitol Region (Washington, D.C, Maryland, and Virginia) completed the SOT and HS-SOT on the NeuroCom® Balance Master™. Parametric and non-parametric comparisons were analyzed for the equilibrium scores for the SOT and HS-SOT conditions 2 (SOT-2, HS-SOT-2, respectively) and 5 (SOT-5, HS-SOT-5, respectively) and the equilibrium score ratios (ESRs) for HS-SOT-2 and HS-SOT-5 for the total sample, men and women, and age group categories (18–26 years, 27–35 years, and 36–45 years). Results There were no differences in HS-SOT-2 or HS-SOT-5 equilibrium ratio scores between men (0.99 ±.029 and 0.83 ±0.25, respectively) and women (1.00 ±0.03 and 0.81 ±0.21, respectively). There were no differences in the SOT-2 equilibrium scores (F = 2.29, P  = 0.10) or SOT-5 equilibrium scores (Kruskal-Wallis H = 3.26, P  = 0.20) among the different age groups. SOT-2 equilibrium scores were higher than the HS-SOT-2 equilibrium scores (Z = –4.10, P  < 0.001). SOT-5 equilibrium scores were also higher than HS-SOT-5 equilibrium scores (Z = –12.22, P  < 0.001), and the HS-SOT-2 and HS-SOT-5 equilibrium scores differed from each other (Z = –13.26, P  < 0.001). Conclusions This study established normative values for the HS-SOT in a military population. Equilibrium scores did not differ between men and women or among age groups, suggesting that these values can be used as reference points for most service members. Postural stability was found to be significantly challenged during head motion, indicating the HS-SOT is a valuable tool for identifying subtle impairments in postural stability. These findings have important implications for early detection and intervention in individuals with medical conditions affecting balance, particularly concussions or vestibular disorders.
