Measurement properties of the Headache Impact Test (HIT-6™ Brazil) in primary and secondary headaches.

Background: The Headache Impact Test-6™ is a widely recommended questionnaire to evaluate the impact of headaches. However, its measurement properties were never evaluated in both primary and secondary headaches, and the Brazilian Portuguese version of the questionnaire was never assessed at all.

Objective: To assess the reliability, and structural and construct validity of the Headache Impact Test-Brazil™ in patients with primary and secondary headaches.

Brazilian Portuguese version of the Headache Disability Inventory: Cross-cultural adaptation, validity, and reliability.

Background: The Headache Disability Inventory assesses the dimensions of headache disability, but it is not available in Brazilian Portuguese yet. We aimed to translate the Headache Disability Inventory into Brazilian Portuguese and analyze its measurement properties.

Methods: Consecutive patients with headaches diagnosed by expert neurologists as per the International Classification of Headache Disorders were included.

Local and widespread hyperalgesia in female runners with patellofemoral pain are influenced by running volume.

Objectives: To compare pressure pain threshold (PPT) around the knee (local hyperalgesia) and at a site remote to the knee (widespread hyperalgesia) between female runners with and without patellofemoral pain (PFP); and to evaluate the relationship between running volume, self-reported knee function and PPT measures.

Design: Cross-sectional study.

Methods: Twenty female runners with PFP and twenty pain-free female runners participated in the study.
