The impact of low back pain and disability on frailty levels in older women: longitudinal data from the BACE-Brazil cohort.

Methods: This is a longitudinal observational study with a convenience subsample from the international Back Complaints in the Elders (BACE)-Brazil. Frailty was assessed by researchers at baseline, 6 and 12 months according to the Frailty Phenotype. Pain was assessed using a Numerical Pain Scale (NPS).

The effect of kinesiophobia in older people with acute low back pain: longitudinal data from Back Complaints in the Elders (BACE).

This study aimed to investigate the course of low back pain (LBP) intensity over a period of 12 months in older people with and without kinesiophobia.This was an international multicenter study. LBP intensity was examined by using the Numerical Pain Scale at baseline and over five follow-up periods.

Use of healthcare services and therapeutic measures associated with new episodes of acute low back pain-related disability among elderly people: a cross-sectional study on the Back Complaints in the Elders - Brazil cohort.

Background: Patients with low back pain frequently undergo a variety of diagnostic and therapeutic interventions, but some of these have uncertain effectiveness. This highlights the importance of the association of healthcare services and therapeutic measures relating to disability.

Objective: To analyze the use of healthcare services and therapeutic measures among Brazilian older adults with disability-related low back pain.

Cross-cultural adaptation and reliability of the pain response to activity and position questionnaire.

Background: The World Health Organization reports that one of the main incapacitating conditions in older adults is osteomusculoskeletal disorders, and among these is low back pain. There are few instruments translated and transculturally adapted with psychometric properties evaluated for older adults with this health condition in Brazil. The Pain Response to Activity and Positioning (PRAP) questionnaire enables classification of older adults through functional performance.
