“…According to Japanese researchers, the presence of cerebral lesions on neuroimaging (strokes, silent cerebral infarctions, microhemorrhages, white matter hyperintensity, dilated perivascular spaces) is associated with more prolonged recovery time from lateropulsion (without taking into account SHN). The duration of lateropulsion in patients with conditionally minor neuroimaging abnormalities was 62.0 (95 % CI, 56.2-67.8) days, while in patients with significant abnormalities, the duration of lateropulsion was 94.0 (95 % CI, 77.0-111.1) days [19]. Probably, more severe cerebral damages are associated with a slower poststroke recovery from lateropulsion.…”

Introduction. In recent years, considerable attention has been paid to the abnormality of body verticality perception in stroke patients. Most often, misperception of body verticality is manifested in the form of lateropulsion and repulsion syndrome. Objective: to study the timing of recovery from lateropulsion (pusher syndrome) and to determine the predictors of lateropulsion resolution in patients with hemispheric strokes. Material and methods. We included in the study patients with hemispheric strokes occurring within the last month. 61 patients were diagnosed with lateropulsion and 9 patients with pusher syndrome, according to the Scale for Contraversive Pushing. After initial examination, patients were subsequently invited for a weekly examination until the body's verticality was normalized. Results. Recovery time from pusher syndrome was significantly longer – 9.0 (95% confidence interval: 7.1–10.4) weeks compared to recovery time from lateropulsion – 5.9 (95% confidence interval: 5.5–6.3) weeks. Among all the studied factors, only spatial hemineglect was a significant independent predictor of a much longer resolution time of lateropulsion (hazard ratio 2.36; 95% confidence interval: 1.20–4.27). The mean duration of lateropulsion in patients with spatial hemineglect was 6.3 (95% confidence interval: 5.8–6.8) weeks, whereas in patients without spatial hemineglect, it was 4.8 (95% confidence interval: 4.3–5.4) weeks. In a subgroup of patients without spatial hemineglect, higher Fazekas scale values were a significant independent predictor of longer resolution time of lateropulsion (hazard ratio 2.38; confidence interval 95%: 1.25–4.48). Conclusions. After hemispheric strokes recovery time from pusher syndrome is much longer than recovery from lateropulsion. Recovery time from lateropulsion is determined by spatial hemineglect and leukoaraiosis severity.

“…In the multivariate Cox regression analysis, SHN remained a significant independent predictor of longer resolution time of lateropulsion (HR 2.36; CI 95 %: 1.20-4.27, p=0.01), whereas the righthemispheric strokes had an HR of 1.52 (CI 95 %: 0.81-2.86, p=0. 19).…”

“…Sue et al. (2022) investigated the differences in the clinical evaluation of 19 patients with Pusher syndrome after stroke by categorizing them into two groups according to the degree of brain damage and studying their progress over 1‐year in a retrospective cohort study. The group with a lesion score of ≥2 had a significantly delayed recovery from PB, and the hazard ratio of the preexisting brain lesion score was 0.458 (95% confidence interval: 0.221, 0.949), while the side of hemiparesis was not a significant covariate.…”

Introduction: Clarifications regarding the recovery process of the subjective postural vertical (SPV) and activities of daily living in stroke patients are required to help clinicians determine treatment plans. Therefore, we aimed to investigate the characteristics of the longitudinal recovery process of SPV and activities of daily living after stroke.Methods: Overall, 109 patients with stroke were enrolled. Clinical assessments included the SPV and total functional independence measure (FIM), initially and after 1 month. The mean and standard deviation of SPV indicated the directional and variability errors, respectively. Participants were categorized as follows: nondeviation group comprised directional and variability errors within the standard values, deviation of variability errors group comprised directional errors within the standard value and variability errors greater than the standard value, and deviation of both directional and variability errors group comprised directional and variability errors greater than the standard values. In addition, a two-way analysis of variance was performed for initial pre-and post-SPV, and pre-and posttotal FIM scores (p < .05). Results:The deviation of variability errors group, and deviation of both directional and variability errors group, had larger SPV variability errors than did the nondeviation group. Furthermore, the deviation of variability errors group showed a significant improvement in variability errors after 1 month. There was a correlation between the initial SPV with eyes opened variability error and total FIM after 1 month in Pusher patients with unilateral spatial neglect in the deviation of both directional and variability errors group.Conclusions: SPV with eyes opened variability errors and initial FIM score may influence the independence of activities of daily living after 1 month in the recovery of patients with stroke with Pusher and unilateral spatial neglect.

“…Karnath et al [11] and Fukata et al [16] reported that the SPV deviated to the paretic or non-paretic side in PB-only cases, and the variability errors of SPV-EO, rather than the SPV deviation, increased in the USN cases. Sue et al [17] investigated the differences in the clinical evaluation of 19 patients with Pusher syndrome after stroke by categorizing them into two groups according to the degree of brain damage and studying their progress over a 1-year period in a retrospective cohort study. The group with a lesion score ≥ 2 had a signi cantly delayed recovery from PB, and the hazard ratio of the preexisting brain lesion score was 0.458 (95% con dence interval: 0.221, 0.949), while the side of hemiparesis was not a signi cant covariate.…”

It is important to clarify the recovery process of the subjective postural vertical (SPV) and activities of daily living (ADL) in stroke to help clinicians determine treatment plans. This study aimed to investigate the characteristics of the longitudinal recovery process of SPV and ADL after stroke. In total, 109 patients with stroke were enrolled in the study. Clinical assessments included the SPV and total functional independence measure (FIM), both initially and after 1 month. The SPV mean and standard deviation values indicated the directional and variability errors, respectively. The participants were categorized as follows: group A had directional and variability errors within the standard values, group B had directional errors within the standard value range and variability errors greater than the standard values, and group C had directional and variability errors greater than the standard values. A two-way analysis of variance was performed for SPV and FIM scores (p < 0.05). Groups B and C had larger SPV variability errors than group A. Furthermore, group B showed a significant improvement in variability errors after 1 month. We found that the recovery of SPV variability might be an important predictor of ADL recovery.
