ABSTRACT

Objective: The current study translated to Portuguese and validated the normal pressure hydrocephalus (NPH) scale originally developed in English as the Grading Scale for Idiopathic Normal Pressure Hydrocephalus.

Methods: Following Guillemin's validation protocol, the last version of the Portuguese NPH scale was applied to 121 consecutive patients with a diagnosis of normal pressure hydrocephalus (73 men and 48 women) from the Group of Cerebral Hydrodynamics from July 2010 to March 2012.

Results: The mean age was 71.09 years old, ranging from 35 to 92 years. The rate of agreement and reproducibility was high, as confirmed by Cohen's Kappa coefficient, with excellent intraobserver correlation for the NPH scale items individually evaluated: gait (0.80), dementia (0.90) and incontinence (0.87).

Conclusions: The Portuguese version of the Grading Scale for Idiopathic Normal Pressure Hydrocephalus was successfully translated and validated for use in Brazilian patients.

RESUMO

Objetivos: o presente estudo valida para a língua portuguesa a escala de hidrocefalia de pressão normal (HPN) desenvolvida em língua inglesa como “Escala de classificação para hidrocefalia de pressão normal idiopática”.

Métodos: Usando o método de Guillemin, uma versão traduzida da escala foi aplicada em 121 pacientes consecutivos com diagnóstico de hidrocefalia de pressão normal (73 homens e 48 mulheres) no Grupo de Hidrodinâmica Cerebral do Hospital das Clínicas da FMUSP de julho de 2010 a março de 2012.

Resultados: a média de idade foi de 71,09 anos, variando de 35 a 92 anos. A taxa de concordância e reprodutibilidade foi alta, conforme confirmado pelo coeficiente Kappa, com excelente correlação intraobservador para itens de escala HPN que avaliou a marcha (0,80), demência (0,90) e incontinência (0,87).

Conclusões: a versão em português da escala de graduação para pacientes com HPN foi traduzida e validada com sucesso para uso em pacientes brasileiros de ambos os sexos.
