ABSTRACT A vestibulospinal test known as the Fukuda stepping test (FST) has been suggested to be a measure of asymmetrical labyrinthine function. However, an extensive review of the performance of this test to identify a peripheral vestibular lesion has not been reported.
The purpose of this study was to evaluate the sensitivity and specificity of the standard FST and a head shaking variation for identification of a peripheral vestibular system lesion.
In this retrospective review, we compared performance on the FST with and without a head shaking component to electronystagmography (ENG) caloric irrigation unilateral weakness results.
We studied these factors in 736 chronic dizzy patients.
Receiving operating characteristics (ROC) analysis and area under the curve (AUC) indicated no significant benefit to performance from the head shaking variation compared to the standard FST in identifying labyrinthine weakness as classified by caloric unilateral weakness results.
These findings suggest that the FST with and without head shake component is not a reliable screening tool for peripheral vestibular asymmetry in chronic dizzy patients; however, future research may hold promise for the FST as a tool for patients with acute unilateral disorders.

    ABSTRACT: Disturbances in static balance have been demonstrated in subjects with persistent whiplash. Some also report loss of balance and falls. These disturbances may contribute to difficulties in dynamic tasks. The aim of this study was to determine whether subjects with whiplash had deficits in dynamic and functional balance tasks when compared to a healthy control group. Twenty subjects with persistent pain following a whiplash injury and twenty healthy controls were assessed in single leg stance with eyes open and closed, the step test, Fukuda stepping test, tandem walk on a firm and soft surface, Singleton test with eyes open and closed, a stair walking test and the timed 10 m walk with and without head movement. Subjects with whiplash demonstrated significant deficits (p < 0.01) in single leg stance with eyes closed, the step test, tandem walk on a firm and soft surface, stair walking and the timed 10 m walk with and without head movement when compared to the control subjects. Specific assessment and rehabilitation directed towards improving these deficits may need to be considered in the management of patients with persistent whiplash if these results are confirmed in a larger cohort.

    ABSTRACT: Falls are a prevalent issue in the geriatric population and can result in damaging physical and psychological consequences. Fall risk assessment can provide information to enable appropriate interventions for those at risk of falling. Wearable inertial-sensor-based systems can provide quantitative measures indicative of fall risk in the geriatric population. Forty studies that used inertial sensors to evaluate geriatric fall risk were reviewed and pertinent methodological features were extracted; including, sensor placement, derived parameters used to assess fall risk, fall risk classification method, and fall risk classification model outcomes. Inertial sensors were placed only on the lower back in the majority of papers (65%). One hundred and thirty distinct variables were assessed, which were categorized as position and angle (7.7%), angular velocity (11.5%), linear acceleration (20%), spatial (3.8%), temporal (23.1%), energy (3.8%), frequency (15.4%), and other (14.6%). Fallers were classified using retrospective fall history (30%), prospective fall occurrence (15%), and clinical assessment (32.5%), with 22.5% using a combination of retrospective fall occurrence and clinical assessments. Half of the studies derived models for fall risk prediction, which reached high levels of accuracy (62-100%), specificity (35-100%), and sensitivity (55-99%). Inertial sensors are promising sensors for fall risk assessment. Future studies should identify fallers using prospective techniques and focus on determining the most promising sensor sites, in conjunction with determination of optimally predictive variables. Further research should also attempt to link predictive variables to specific fall risk factors and investigate disease populations that are at high risk of falls.

    ABSTRACT: Abstract Background: Laboratory vestibular tests are relatively expensive and may be not available in every clinic. On the other hand, office vestibular tests can be easily performed and are low-cost. Objectives: To measure the sensitivity of a proposed battery approach to be conducted as an office procedure to diagnose side and site of vestibular lesions. Methods: This study was conducted on 36 patients suffering from vertigo with a confirmed diagnosis of vestibular disorder by laboratory vestibular tests. These included a standard video nystagmography (VNG) test that entails recording of eye examination including gaze testing, saccadic eye movements and smooth pursuit together with positional and positioning examinations as well as bithermal calorics and Vestibular Evoked Myogenic Potential (VEMP) tests. Patients were evaluated independently by history, examination of eye movements and a battery of office vestibular tests that included the Head Shake nystagmus Test (HST), Head Thrust Test (HTT) and Fukuda Stepping Test as well as the Dix-Hallpike test. Audiological, radiological and laboratory tests were applied to establish aetiological diagnosis whenever indicated. Results and conclusions: One patient showed abnormal eye movements that were confirmed by full diagnostic work-up for vestibular disorders in keeping with a diagnosis of multiple sclerosis, and was excluded from forthcoming analysis. Sensitivity of the HST test with respect to results of the laboratory vestibular tests (VNG and VEMP) was 51.5% while that of HTT was 43%. Moreover, the Fukuda Stepping Test showed a sensitivity of 48.5% with non-significant correlation to the side of caloric weakness and a significant correlation to the side of abnormal VEMP response. The proposed battery of office vestibular tests proved to be a quick screening approach that was successful in helping to identify site and side of peripheral vestibular lesions in 77% of patients. On the other hand, normal office vestibular tests were obtained in patients with laboratory findings showing mild caloric weakness or with only an abnormal VEMP.
