Although most research on spatial neglect (SN) has focused on spatial perception deficits with regard to the lateral (left-right) axis, deficits of spatial perception with regard to the vertical (up-down) axis, such as disturbances in the perception of verticality (e.g., judgement of vertical orientations), have also been suggested.
We aimed to systematically analyse reported associations between SN and characteristics of verticality perception while considering the time post-stroke.
PubMed, Web of Science, Scopus, PubPsych and PsycArticles databases were searched on May 24, 2022 for articles written in English that evaluated the association between SN and verticality perception (i.e., the subjective visual vertical [SVV], subjective postural vertical [SPV] and subjective haptic vertical [SHV]) in adults after stroke. Left and right SN were considered and had to be assessed using standardized methods. Data were manually extracted, and risk of bias was assessed with the Newcastle-Ottawa Scale. The tilt of the line/chair relative to the gravitational vector and its direction, together with uncertainty (i.e., variability across measurements), were evaluated.
Thirteen studies were included (431 participants after stroke); at least 191 participants exhibited SN. Mainly the first 3 to 6 months post-stroke were evaluated. SN was associated with SVV misperception, which resulted in larger SVV tilts (mostly in the contralesional direction) and uncertainty in participants with than without SN. SVV tilt magnitudes ranged from a mean/median of -8.9° to -2.3° in SN participants and from -1.6° to 0.6° in non-SN participants, the latter falling within normative ranges. For SPV and SHV measurements, the magnitude of tilt and the uncertainty were insufficiently assessed or results were inconclusive.
SN was associated with larger SVV tilts and uncertainty, which suggests that SVV misperception is a key feature of SN. This observation highlights the importance of regular SVV assessment in people with SN in clinical practice.

尽管大多数空间忽视（SN）的研究都集中在横向（左右）轴的空间感知缺陷上，但也有人提出了垂直（上下）轴的空间感知缺陷，例如垂直性感知障碍（例如，垂直方向的判断）。
我们旨在系统分析报告的 SN 与垂直性感知特征之间的关联，同时考虑到中风后的时间。
我们于 2022 年 5 月 24 日在 PubMed、Web of Science、Scopus、PubPsych 和 PsycArticles 数据库中检索了以英文发表的评估成人中风后 SN 与垂直性感知（即主观视觉垂直[SVV]、主观姿势垂直[SPV]和主观触觉垂直[SHV]）之间关联的文章。考虑到左 SN 和右 SN，并且必须使用标准化方法进行评估。手动提取数据，并使用纽卡斯尔-渥太华量表评估偏倚风险。评估了线/椅相对于重力向量的倾斜度及其方向，以及不确定性（即测量值之间的可变性）。
纳入了 13 项研究（431 名中风后患者）；至少有 191 名患者表现出 SN。主要评估了中风后 3 至 6 个月。SN 与 SVV 感知错误有关，导致 SN 患者的 SVV 倾斜度（主要在对侧方向）更大且不确定性更大。SN 患者的 SVV 倾斜度幅度范围从平均/中位数-8.9°到-2.3°，非 SN 患者的 SVV 倾斜度幅度范围从-1.6°到 0.6°，后者落在正常范围内。对于 SPV 和 SHV 测量，倾斜度的幅度和不确定性评估不足或结果不确定。
SN 与更大的 SVV 倾斜度和不确定性有关，这表明 SVV 感知错误是 SN 的一个关键特征。这一观察结果强调了在临床实践中对 SN 患者进行常规 SVV 评估的重要性。
