Abstract:
ObjectiveTo explore the impact of subjective vertical perception impairment after stroke on visuospatial cognition, balance, walking and activities of daily living, to investigate the mediating role of visuospatial cognition and lateropulsion. MethodsFrom February to December, 2023, 96 stroke patients were selected from the Rehabilitation Medicine Center of the First Affiliated Hospital of Nanjing Medical University. They were divided into vertical perception impairment group (n = 53) and non-vertical perception impairment group (n = 43). They were assessed with National Institutes of Health Stroke Scale (NIHSS), the Scale for Contraversive Pushing (SCP), Burke Lateropulsion Scale (BLS), Line Bisection Test (LBT), Line Cancellation Test (LCT), Star Cancellation Test (SCT), Subjective Visual Vertical (SVV), Berg Balance Scale (BBS), Holden Functional Ambulation Categories (FAC) and Barthel Index (BI). ResultsScores of SVV orientation, SVV uncertainty, NIHSS, SCT, SCP, BLS, BBS, FAC and BI were worse in the vertical perception impairment group than in the non-vertical perception impairment group (|t| > 2.414, Z = -3.481, P < 0.05). Scores of SVV were correlated with SCT, BLS and BBS (|r| ≥ 0.273, P < 0.05). After controlling for age and gender, SVV orientation score did not directly impact BBS score (β = -0.011, P = 0.920). However, it exerted a partial mediating effect through BLS (effect = -0.173, 95%CI -0.278 to -0.076) and a chain-mediated effect through SCT and BLS (effect = -0.073, 95%CI -0.137 to -0.027), impacting BBS score. ConclusionSubjective vertical perception impairment results in poorer visuospatial cognition, balance, walking and activities of daily living in stroke patients. This influence on balance function is mediated through the mediating effects of visuospatial cognition and lateropulsion.
