INTRODUÇÃO:O objetivo deste estudo foi comparar a escala de incapacidade motora de Osame e a escala expandida do estado de incapacidade de Kurtzke com a escala para avaliação da paraplegia espástica com o objetivo de avaliar a clinica dos pacientes com mielopatia associada a HTLV-I/paraparesia espastica tropical (PET/MAH). MÉTODOS: Foram incluídos pacientes com diagnóstico de infecção pelo HTLV-I/HTLV-II e a suspeita clinica de PET/MAH. RESULTADOS: Foram avaliados 45 pacientes. Ao analisar os resultados das escalas encontramos as seguintes médias de 21,08 pontos para a escala para paraplegia espástica, 4,35 pontos para a escala de Osame e 4,77 pontos para a de Kurtze. A relação entre a escala de paraplegia com a de Osame foi muito significativa com p < 0.0001, e com relação a escala de Kurtze obteve resultado semelhante com p < 0.0001, também significante. Comparando-se as escalas de Osame, Kurztze e escala para avaliação da paraplegia espástica com o tempo de doença obtivemos um resultado significante com p=0,0004, para a escala de paraplegia espastica, p = 0,0018 para a escala de Osame e p < 0,0001 para a escala de Kurtzke. CONCLUSÕES: A escala da paraplegia espástica possui boa relação com as escalas de Osame e Kurzte, mostrando um p muito significativo, indicando que apesar da escala não ter sido feita inicialmente para ser aplicada aos pacientes com PET/MAH devido à infecção pelo HLTV, ela se mostrou capaz de ser tão eficiente quanto às escalas de Osame e Kurtzke para avaliar o quadro neurológico dos pacientes.
INTRODUCTION:The objective of this study was to compare Osame's scale of motor incapacity and the expanded scale of the state of incapacity of Kurtzke with the spastic paraplegia rating scale for the clinical evaluation of patients with HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). METHODS: Patients with the diagnosis of infection by HTLV-I/HTLV-II and with the clinical suspicion of HAM/TSP were included in the study. RESULTS: There were 45 patients who were evaluated. When analyzing the results of the scales, the researchers found the following averages of 21.08 points for the spastic paraplegia rating scale, 4.35 points for Osame's scale, and 4.77 points for Kurtzke's scale. The relation between the scale of paraplegia with Osame's was very significant with p < 0.0001, and regarding Kurtzke's scale, there was a similar result of p < 0.0001. When comparing Osame's, Kurtze's, and the spastic paraplegia rating scale with the time of disease, the researchers found a significant result of p = 0.0004 for the scale of spastic paraplegia, p = 0.0018 for Osame's scale, and p < 0.0001 for Kurtzke's scale. CONCLUSION: The spastic paraplegia rating scale has a good relation with Osame's and Kurtzke's scales showing a p index that is very significant that indicates that, although the scale was not initially made to be applied to patients with HAM/TSP because of the infection by HLTV, it showed to be as efficient as Osame's and Kurtzke's scales in evaluating the patients' neurological conditions.
