Abstract

The Visual Function Classification System (VFCS) provides a standardised framework for grading visual functioning in children with cerebral palsy (CP). This study evaluated the reliability and construct validity of the Croatian VFCS, and its ability to distinguish visual functioning across CP subtypes and functional classifications. Ninety-five children with CP (mean age: 11.8 years, range: 4-18) were assessed using VFCS, Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Communication Function Classification System (CFCS). Reliability was tested using quadratic weighted kappa and intraclass correlation coefficients (ICCs); differences across CP types with the Kruskal-Wallis, and construct validity with Spearman correlations. The Croatian VFCS showed excellent interrater (κ = 0.87) and intrarater reliability (κ = 0.92), with ICCs greater than 0.90. VFCS levels differed significantly by CP subtype (χ² = 8.30, P = 0.016), with preliminary evidence suggesting that unilateral spastic CP may be associated with better visual function than bilateral spastic or dyskinetic CP. Moderate correlations with CFCS (ρ = 0.557), MACS (ρ = 0.392), and GMFCS (ρ = 0.308) revealed clinically relevant divergences between visual and motor abilities. The Croatian VFCS is a reliable, valid, and clinically sensitive tool. This study provides preliminary evidence of its discriminative utility across CP subtypes and supports integrating VFCS into multidisciplinary assessment and individualised rehabilitation planning.

脑瘫患者克罗地亚视觉功能分类系统及亚型特异性差异的验证。
视觉功能分类系统(VFCS)为脑瘫儿童的视觉功能分级提供了一个标准化的框架。本研究评估了克罗地亚VFCS的信度和结构效度,以及其区分不同CP亚型和功能分类的视觉功能的能力。采用VFCS、大肌肉运动功能分类系统(GMFCS)、手工能力分类系统(MACS)和沟通功能分类系统(CFCS)对95例CP患儿(平均11.8岁,范围4 ~ 18岁)进行评估。采用二次加权kappa和类内相关系数(ICCs)检验信度;不同CP类型的差异与Kruskal-Wallis相关,建构效度与Spearman相关。克罗地亚VFCS具有良好的间信度(κ = 0.87)和内信度(κ = 0.92), ICCs均大于0.90。不同CP类型的VFCS水平差异显著(χ²= 8.30,P = 0.016),初步证据表明单侧痉挛性CP可能比双侧痉挛性或运动障碍CP与更好的视觉功能相关。与CFCS (ρ = 0.557)、MACS (ρ = 0.392)和GMFCS (ρ = 0.308)的中度相关性显示了视觉和运动能力之间的临床相关差异。克罗地亚VFCS是一种可靠、有效和临床敏感的工具。本研究为其在CP亚型间的鉴别效用提供了初步证据,并支持将VFCS整合到多学科评估和个性化康复计划中。

期刊介绍: International Journal of Rehabilitation Research is a quarterly, peer-reviewed, interdisciplinary forum for the publication of research into functioning, disability and contextual factors experienced by persons of all ages in both developed and developing societies. The wealth of information offered makes the journal a valuable resource for researchers, practitioners, and administrators in such fields as rehabilitation medicine, outcome measurement nursing, social and vocational rehabilitation/case management, return to work, special education, social policy, social work and social welfare, sociology, psychology, psychiatry assistive technology and environmental factors/disability. Areas of interest include functioning and disablement throughout the life cycle; rehabilitation programmes for persons with physical, sensory, mental and developmental disabilities; measurement of functioning and disability; special education and vocational rehabilitation; equipment access and transportation; information technology; independent living; consumer, legal, economic and sociopolitical aspects of functioning, disability and contextual factors.
