Abstract
OBJECTIVE: To translate and validate the Spastic Paraplegia Rating Scale (SPRS) into Brazilian-Portuguese. METHOD: Two experienced and English-fluent neurologists translated SPRS into Portuguese, creating SPRS-BR. We then assessed inter and intra-rater reliability of this version using coefficients of correlation and variability in a cohort of 30 patients. RESULTS: Mean age of patients and disease duration were 47.7 ± 10.5 and 17.0 ± 10.6 years, respectively. Twenty-one had pure HSP and SPG4 was the most frequent genotype. Mean Rankin and SPRS-BR scores were 2.2 ± 0.9 and 19.9 ± 9.9, respectively. Mean intra and inter-rater correlation coefficients of SPRS-BR scores were 0.951 and 0.934, whereas coefficients of variation were 11.5% (inter-rater) and 9.9% (intra-rater). Cronbach's alpha for the whole SPRS-BR scale was 0.873. CONCLUSION: SPRS-BR is a useful, reliable and valid clinical instrument.
