“…Previous research showed that head and trunk fixation during the SVV measurement resulted in difference in deviation and increased individual variability compared to conditions without trunk (and head) fixation [49]. As variability is considered a criterion for the validity of the measurement, this indicates that measurements without these fixations are less valid [28,49]. Head-to-body position could also influence the E-effect, indicating a deviation of the subjective vertical toward the opposite side of the starting head-on-body position.…”

Background: Lateropulsion with active Pushing (LwP) is characterized by impairments in postural control. Previous research suggests an association between LwP, lesion location and verticality misperception. This first-ever systematic review evaluates the association between LwP, lesion location and the perception of verticality (PROSPERO: CRD42020159248). Methods: Pubmed, Web of Science, REHABDATA, Embase, Cochrane Library and PEDro were systematically searched on December 16th, 2021. Studies were included when examining lesion location or perception of verticality (Subjective Haptic, Visual or Postural Vertical) in supratentorial stroke patients showing LwP . Two reviewers independently screened and assessed risk of bias using the Newcastle Ottawa Scale. Data was qualitatively analysed and extracted.Results: Nineteen studies were included, examining a total of 340 LwP patients. Lesions in: the thalamus, internal capsule, inferior parietal lobule at the junction of the postcentral gyrus, the posterior insula and the superior temporal gyrus, were associated with LwP. Whereas all studies examining the Subjective Postural and Haptic Vertical (haptic only examined once) reported a significant increased deviation in LwP patients, inconsistent results were found for the Subjective Visual Vertical. Furthermore, the Subjective Visual and Postural Vertical showed inconsistent results for magnitude, direction and variability of this deviation.Discussion: A complex brain network, rather than only one brain region, seems responsible for body control with respect to gravity. A disruption within this network might lead to a bias in the construction of a correct internal reference frame, crucial for perceiving verticality. There was an association of LwP with verticality misperception in all three modalities. * ** * * * 8 Good Dai et al., 2021 [35] * * * ** * * * 8 Good Fraser et al., 2018 [30] * * * 3 Poor Fukata et al., 2020 [36] * * * ** * * * 8 Good Fukata et al., 2020 [37] * * * ** * * * 8 Good Karnath et al., 2000 [26] * * * * * * 6 Poor Paci et al., 2011 [41] * * * * ** * * * 9 Good Perennou et al., 2008 [2] * * * * ** * * * 9 Good Saj et al., 2005 [42] * * * * * * * * 8 Good Snowdon et al., 2005 [31] * * * * * 5 Poor

“…We also found that trunk control, as assessed by TIS, was negatively correlated with SVV and SHV. A previous study showed that trunk and head orientation impacted SVV measurements, especially in patients with postural disorders (Piscicelli et al, 2016). Martins et al (2021) reported that there is frequent loss of selective control of the trunk muscles after a stroke event, leading to an asymmetric posture and difficulty in distributing body weight support to the affected side.…”

Analysis of Verticality Perception in Older Adults With and Without Acute Stroke in Half-Lying Versus Sitting Positions

et al. 2022

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.

“…É relevante ressaltar que as perturbações de VV podem ser classificadas em VV de orientação (VVo) e VV de incerteza (VVi). Na VVo, a percepção é estimada pelo cálculo da média dos valores reais (positivos e negativos) das tentativas (BARRA et al, 2010;BONAN et al, 2006aBONAN et al, , 2007PISCICELLI et al, 2016;YELNIK et al, 2002).…”

“…A VVi, possui duas principais maneiras de ser estimada: pelo desvio padrão dos valores reais (VVi-dp) (BARRA et al, 2010;BONAN et al, 2006aBONAN et al, , 2007PISCICELLI et al, 2016) ou pela média dos valores absolutos (em módulo) (LOMAS-VEGA et al, 2023;PETERCHEV et al, 2012;SANTOS-PONTELLI et al, 2016;SANTOS et al, 2018;TESIO;LONGO;ROTA, 2011). Entretanto, não há estudos que descreveram os resultados e compararam as frequências de distúrbio de VV em relação às três estimativas, como realizados no presente trabalho.…”
