Abstract Background: Verticality misperception is relatively common among patients after stroke, and it may be evaluated in terms of (a) subjective visual vertical (SVV), (b) subjective haptic vertical (SHV) and (c) subjective postural vertical (SPV). To better understand these assessment methods, we conducted a systematic review of the methodological characteristics of different protocols for evaluating SVV, SHV and SPV among individuals after stroke. Objective: To standardize the methodological characteristics of protocols for evaluating verticality perception after stroke. Methods: We searched the following databases: PUBMED, regional BVS portal (MEDLINE, LILACS, IBECS, CUBMED, Psychology Index and LIS), CINAHL, SCOPUS, Web of Science, Science Direct, Cochrane Library and PEDro. Two review authors independently used the QUADAS method (Quality Assessment of Diagnostic Accuracy Studies) and extracted data. Results: We included 21 studies in the review: most (80.9%) used SVV, eight (38.1%) used SPV and four (19.0%) used SHV. We observed high variability in assessments of verticality perception, due to patient positions, devices used, numbers of repetitions and angle of inclination for starting the tests. Conclusion: This systematic review was one of the first to explore all the methods of assessing verticality perception after stroke, and it provides crucial information on how to perform the tests, in order to guide future researchers/clinicians.

Objective To analyze the results of the subjective visual vertical test using the “bucket method” in patients with chronic suppurative otitis media (CSOM). Study Design Cross-sectional, controlled study. Setting Outpatient otology clinic in a tertiary care hospital. Subjects and Methods Patients had CSOM, defined as the presence of chronic infection or inflammation of the middle ear cleft, associated with a perforation of the tympanic membrane, frequent or intractable middle ear suppuration, with or without cholesteatoma. Controls were selected using a nonprobability, purposive sampling method. We excluded patients with neurologic or metabolic diseases, cognitive deficits, otosclerosis, vestibular migraine, Ménière’s disease, past use of ototoxic medication, or head and neck cancer. The volunteers were subjected to the subjective visual vertical test using the “bucket method.” The results obtained in our study and control groups were analyzed using nonparametric tests. Results Our study comprised 51 patients with CSOM and 50 controls. In the CSOM group, we observed that 72.5% of the patients had vestibular symptoms in the past year, and 70.5% had abnormalities identified in at least 1 vestibular function test. The subjective visual vertical test revealed that patients with CSOM (with and without cholesteatoma) had significantly higher deviations of the true vertical as compared with controls (CSOM, 3.66°; controls, 0.76°; P < .001). Conclusion Our results revealed that CSOM was associated with high rates of vestibular symptoms, abnormal vestibular function tests, and abnormal subjective vertical visual results.

INTRODUCTION Subjective Visual Vertical test (SVV test) can be applied to measure one of the functions of the vestibular apparatus, its afferent pathways and nuclei within the brain stem. The test is based on the subjective assessment of verticality. The possibility of perceived visual vertical in healthy subjects can show deviation with accuracy of ?2? at most. OBJECTIVE The goal of the study is to present the results of the SVV test developed at our department. METHOD Two kinds of testing procedures were applied; the static test during which the subjects evaluated the verticality on a static background; the dynamic test during which the subjects evaluated the verticality after 20 seconds of rotation of the background to the right or to the left. Ninety-five healthy subjects aged between 21 and 79 years were tested. The whole group was divided into smaller groups according to age criterium. RESULTS The results showed statistically significant bigger SVV tilt in the subjects aged over 45 years than in the younger subjects. The arithmetic mean of the tilt to the left or tilt to the right in the group younger than 45 years was 0.42 degrees during the static test and 0.49 degrees during the dynamic test. The arithmetic mean for the group older than 45 years was 0.67 during the static test and 0.68 during the dynamic test. CONCLUSION The testing indicated that SVV perception showed a bigger tilt according to age. This should be taken into consideration in individual testing and evaluation of functional ability.

Background: The otoliths act as gravito-inertial force sensors and contribute to the perception of spatial orientation. The perception of gravitational vertical can be assessed by asking a subject to adjust a light bar to the vertical. Prior to clinical use of the SVV (subjective visual vertical) test, normative data and test-retest reliability must be established. Purpose: To obtain normative data and d etermine the test-retest reliability for the SVV test performed in static and dynamic test conditions. Research Design: A descriptive design was used to obtain normative data. Study Sample: Twenty-four young adults with no history of neurological disease, middle-ear pathology, open or closed head injury, cervical injury, or audiovestibular disorder participated in the study. Data Collection and Analysis: The SVV angle was measured in the static position and in three dynamic conditions: (1) on-axis clockwise (CW) rotation, (2) off-axis CW rotation of right ear, and (3) off-axis CW rotation of left ear. Results: In young healthy individuals, the SVV was <2° for static and on-axis rotation, and shifted up to 11° during unilateral centrifugation. Test-retest reliability of the SVV was good for all test conditions. Conclusions: The normative data obtained in this study may be useful in identifying patients with chronic utricular dysfunction. We recommend the use of difference angles (on-axis SVV – off-axis SVV) to remove baseline bias and decrease the variability of the SVV angles for the off-axis conditions.
