Background ContextThe study of low back pain (LBP) is complex, and the physical and psychological aspects, including kinesiophobia, should be considered. Several studies have investigated the relationship between kinesiophobia and functionality in patients with chronic LBP. However, to the best of the authors' knowledge, no studies have investigated the association between kinesiophobia and self-reported assessments of disability and physical performance in elderly patients with acute LBP.PurposeThe study aimed to investigate the association between kinesiophobia and self-reported and physical performance measures among the elderly with acute LBP.DesignThis was an observational, cross-sectional, ancillary study of the Back Complaints in the Elders study, a longitudinal observational epidemiologic research project by an international consortium involving Brazil, the Netherlands, and Australia.Patient SampleSample selection was carried out by convenience. The study included women from the community aged 60 years old and older who presented with a new episode of LBP. Volunteers with severe diseases, as well as visual, hearing, and mobility losses, or cognitive dysfunction, were excluded. Four hundred fifty nine elderly women (mean age: 69.0±6.1 years) were included.Outcome MeasuresKinesiophobia was evaluated by Fear Avoidance Beliefs Questionnaire (FABQ), subscale FABQ-Phys. Functionality was investigated by the Roland-Morris Questionnaire and the gait speed test.MethodsStatistical analysis was performed using hierarchical linear regression model. Statistical significance was established at the level of .05.ResultsThe additional predictive value because of the inclusion of the FABQ-Phys was 0.1%, using the Roland-Morris score, and 0.2% for the gait speed test.ConclusionsThis was the first study to investigate the association between the FABQ-Phys and functionality in elderly patients with acute LBP. The results provide preliminary evidence that kinesiophobia assessed by the FABQ-Phys cannot be generalized to disability.Copyright © 2016 Elsevier Inc. All rights reserved.
