“…The participants performed six repetitions of this procedure, three toward the right and three toward the left. The mean perceived vertical position in the right and left directions were used as the final values (de Souza et al, 2021; Ferreira et al, 2016). SVV was classified as absolute and constant errors, based on the participant’s perception of the vertical line.…”

“…Only the absolute values of the SVV measurements, without positive or negative arithmetic signs were considered for the absolute SVV. Constant SVV considers the positive and negative SVV values (Conceição et al, 2018; de Souza et al, 2021; Piscicelli & Pérennou, 2017).…”

“…To measure the SHV, we used a device comprised of a box (diameter 18.5 × 18.5 × 30 cm) and a circular rod (15 cm long and 2.5 cm thick). The rod was mounted at the center of the box (de Souza et al, 2021). The rod height was adjusted according to the participant’s height so that the center of the rod was approximately at elbow level.…”

Currently, there is no research consensus regarding the influence of body position on verticality perception in acute stroke. In this study, we aimed to compare the influence of half-lying and sitting positions on measurements of the subjective visual vertical (SVV) and the subjective haptic vertical (SHV) of individuals in the acute stroke phase. In this cross-sectional study, we compared these positional experiences in two groups of participants: adults in the acute stroke phase and elderly individuals without stroke. Independent variables were stroke versus no-stroke groups, in half-lying versus sitting positions. Analyzed variables of related interest were cognition (Mini-Mental State Examination or MMSE), stroke severity (National Institutes of Health Stroke Scale or NIHSS), and trunk control (Trunk Impairment Scale or TIS). Dependent variables were visual and haptic verticality, as evaluated by SVV and SHV. There were observed differences in absolute SVV in sitting position between groups ( p = 0.021), absolute SVV in half-lying position between groups ( p = 0.033), absolute SHV in sitting position between groups ( p = 0.003), absolute SHV in half-lying position between groups ( p = 0.002), and constant SVV in half-lying position between groups ( p = 0.007). In the stroke group there was a higher coefficient of variation of SVV and SHV in the half-lying position compared to sitting position. In the sitting position, we observed a very strong correlation between the TIS and absolute SHV ( p = 0.008). We concluded that individuals in the acute phase of stroke had greater misperceptions of visual and haptic verticality than older adults without strokes and that individuals in the acute phase of stroke showed less variability in visual and haptic vertical perception in the sitting position than in the half-lying position. By implication, we should encourage the sitting position in the acute stroke phase and develop early strategies to increase the verticality perception.

“…The participants were divided into 2 groups: hospitalized patients with post-COVID-19 (hospitalized group) and nonhospitalized patients with post-COVID-19 (non-hospitalized group). They were assessed using the sit-to-stand test, [24][25][26] grip strength, [27][28][29][30] painful and tactile sensory assessment, 31 visual acuity, 32 vestibular assessment, [33][34][35] verticality perception by subjective visual vertical (SVV), [36][37][38][39] and subjective haptic vertical (SHV) tests. [38][39][40] All clinical tests were performed by an authorized and trained researcher.…”

Background SARS-CoV-2 infection affects multiple systems, including musculoskeletal, neurological, and respiratory systems. Changes associated with physical inactivity due to prolonged hospitalization can affect the functional capacity of individuals with long coronavirus disease 2019 (COVID-19) or post-COVID-19 condition and may cause changes in some postural control functions, such as verticality. Objectives This study aimed to evaluate the perception of verticality in individuals with long COVID. Design Cross-sectional study Methods This study included 60 participants with post-COVID-19 condition divided into 2 groups: hospitalized group (n = 24), those hospitalized owing to SARS-CoV-2 infection; and non-hospitalized group (n = 36), those infected with SARS-CoV-2 but not hospitalized. All participants were examined using a post-COVID-19 functional status (PCFS) , sit-to-stand test, grip strength assessment, painful and tactile sensory assessments, visual acuity assessment, and vestibular assessment. Verticality perception was evaluated using the subjective visual vertical (SVV) and subjective haptic vertical (SHV) tests. In both tests, the absolute values (positive values only) and true values (positive and negative values) were considered. To verify potential confounders that could influence the verticality of the results, logistic regression models were used for categorical variables and multiple linear regressions were used for continuous variables. For analysis between groups, the independent samples test (Mann–Whitney U test) was used. Results There were no confounders between clinical variables and verticality in either group. There was a significant increase in absolute SVV (mean deviation [MD]: 2.83; P < .0001) and true SVV (MD: −4.18; P = .005) in the hospitalized group compared to the non-hospitalized group. Furthermore, there was a significant increase in the true SHV (MD: −3.6; P = .026) in the hospitalized group compared to that in the non-hospitalized group. Conclusion Less accurate visual and haptic verticality perception task performance was observed in hospitalized patients with post-COVID-19 condition.
