title: [Translation and validation of an instrument for evaluation of severity of symptoms and the functional status in carpal tunnel syndrome].
abstract: The objective of the present study was to translate, to do cultural equivalence and validation of the Levine et al. (1993) or Boston Carpal Tunnel Questionnaire (BCTQ) to Portuguese. The BCTQ application to patients, selected by the question "What was the reason that brought you to look for a physician and that led him to ask this examination?" showed very good reproducibility. The validity was measured through the comparison of the severity symptoms scores (SSS) and the functional status scores (FSS) with the results of grip forces, Minnesota, two point discrimination, Semmes-Weinstein filaments perception and sensory conduction at the median nerve. The internal consistency was evaluated through Chronbach's alpha coefficient comparing the SSS and the FSS. The measuring properties were evaluated through paired t-test between pre and pos-surgical scores. Reproducibility, internal consistency, validation and measuring properties of the translated BCTQ were similar to those found by Levine et al. with the original version.
