Development of the Brazilian Portuguese version of the Achilles Tendon Total Rupture Score (ATRS BrP): a cross-cultural adaptation with reliability and construct validity evaluation.

Background: There is a need for a patient-relevant instrument to evaluate outcome after treatment in patients with a total Achilles tendon rupture. The purpose of this study was to undertake a cross-cultural adaptation of the Achilles Tendon Total Rupture Score (ATRS) into Brazilian Portuguese, determining the test-retest reliability and construct validity of the instrument.

Methods: A five-step approach was used in the cross-cultural adaptation process: initial translation (two bilingual Brazilian translators), synthesis of translation, back-translation (two native English language translators), consensus version and evaluation (expert committee), and testing phase.

Characterization of hip passive stiffness of volleyball, basketball and futsal young athletes.

Objectives: (1) To establish the reference values of the test of 'Position of hip passive resistance against gravity' (PHPR) in young athletes; (2) To investigate differences between the values of PHPR test according to athlete's sex, age and sport practiced.

Design: Cross-sectional.

Setting: Sports club.
