Outline
To identify latent classes of fall risk perception in patients with posterior circulation ischemia(PCI),and to analyze their influencing factors,and to explore the impact of different classes on exercise self-efficacy.
A total of 200 PCI patients admitted to our hospital from August 2023 to July 2025 were enrolled.Surveys included a general information questionnaire,the Fall Risk Perception Scale,Pittsburgh Sleep Quality Index(PSQI),Berg Balance Scale(BBS),Exercise Self-Efficacy Scale(MSES),and Activities of Daily Living(ADL) scale.Latent profile analysis(LPA) was used to identify latent classes of fall risk perception and their influencing factors.The impact of these classes on exercise self-efficacy was further examined.
Fall risk perception in PCI patients fell into three latent classes:insufficient perception(78 cases,39.0%),moderate perception(92 cases,46.0%),and excessive perception(30 cases,15.0%).Multivariate logistic regression showed that PSQI score was a factor for the insufficient perception class(OR=1.553,P<0.001).BBS score,ADL score,MSES score,and fall history were factors for the excessive perception class(OR=0.840,0.882,0.933,and 2.945 respectively,P<0.05).Multiple linear regression showed that after controlling for confounders,the excessive perception class was a predictor of exercise self-efficacy score(P<0.05).
Fall risk perception in PCI patients showed population heterogeneity and it was influenced by sleep quality,balance function,and daily activity ability.The excessive perception class negatively predicted patients' exercise self-efficacy. Clinicians may consider identifying different patient classes and develope targeted intervention strategies.
