Comparative Study
Cross-cultural adaptation and validation of the Brazilian Portuguese version of the Neck Disability Index and Neck Pain and Disability Scale.
This study's design was a cross-cultural validation of the Neck Disability Index and Neck Pain and Disability Scale. ⋯ A reliable and valid Portuguese version of the Neck Disability Index and Neck Pain and DisabilityScale was developed, which will facilitate the examination of functional performance within a large patient population, as well as cross-cultural comparisons.

Systematic review. ⋯ Based on the current evidence, intermittent or continuous traction as a single treatment for LBP cannot be recommended for mixed groups of patients with LBP with and without sciatica. Neither can traction be recommended for patients with sciatica because of inconsistent results and methodological problems in most of the studies involved. However, because high-quality studies within the field are scarce, because many are underpowered, and because traction often is supplied in combination with other treatment modalities, the literature allows no firm negative conclusion that traction, in a generalized sense, is not an effective treatment for patients with LBP.

Prospective cohort study. ⋯ Poor overall physical function and depression symptomatology are associated with LBP and consequences of LBP in persons 70 years of age and older.

Psychometric testing of a translated, culturally adapted questionnaire. ⋯ The ODI-G is valid, reliable, and responsive. It may be used to measure current state as well as changes in health status, and allows for cross-cultural comparisons. Further research comparing the 2 versions in German language seems to be necessary.
