Fear Avoidance Beliefs and physical function in elderly individuals with chronic low back pain

Fear Avoidance Beliefs and physical function in elderly individuals with chronic low back pain This analysis assessed how fear avoidance beliefs (FABs) affected subjective and objective functional parameters as well as pain in elderly individuals. The study comprised 152 elderly patients with low back pain, which was attributed to spondylosis in almost half of the cases. Their average age was 70.1 years (SD=4.3, range 65-84). All of the patients participated in a physiotherapeutic program including data acquisition before treatment (t1), immediately after its completion (t2), and 6 months later (t3). FABs were assessed by a five-item scale with satisfying psychometric properties. The primary outcome criterion was function, which was evaluated as a subjective measure using the Hannover functional disability scale and as an objective measure based on the anteflexion determined by ultrasound topometry. Secondary outcome criteria were pain parameters. At the time o the first measurement (t1), the patients were classified into three groups with strong, intermediate, or weak FABs. Analyses of variance reveal an improvement of subjective functional capacity in every FAB group between t1 and t2. At t3, there is a decline of these values only in the group of the high fear avoiders. High fear avoiders also show lower values in the objective measure at all three measurement points. No influence of the FABs on the pain parameters could be determined. It would be expected that the efficacy of physiotherapy could be improved if the patients' FABs are taken into consideration when planning the treatment regimen.
