Background And PurposeEvidence-based practice aims to improve patient care and service delivery, particularly in the management of individuals with low back pain (LBP), the largest client group seen by outpatient physical therapists. The purpose of this study was to determine the prevalence of use of interventions with evidence of effectiveness in the management of acute nonspecific LBP by physical therapists.SubjectsA multicenter cross-sectional study was conducted on 100 physical therapists working with patients with LBP.MethodsUsing a telephone-administered interview, therapists described their current and desired treatment practices for a typical case of LBP. Each intervention reported was coded according to its evidence of effectiveness (strong, moderate, limited, or none). Information on clinician, workplace, and client characteristics also was obtained.ResultsThe prevalence of use of interventions with strong or moderate evidence of effectiveness was 68%. However, 90% to 96% of therapists also used interventions for which research evidence was limited or absent. Users of interventions with high evidence of effectiveness, as compared with nonusers, had graduated more recently and had taken a higher number of postgraduate clinical courses.Discussion And ConclusionAlthough most therapists use interventions with high evidence of effectiveness, much of their patient time is spent on interventions that are not well reported in the literature. The results indicate the need for improvement in the quality of clinical research as well as its dissemination and implementation in a way that is appealing to therapists, such as through practice-related courses.
