Twenty-five years with the biopsychosocial model of low back pain - is it time to celebrate? A report from the Twelfth International Forum for Primary Care Research on Low Back Pain.
ABSTRACT Study Design. An integrated review of current knowledge about the biopsychosocial model of back pain for understanding aetiology, prognosis and interventions, as presented at the plenary sessions of theXII International Forum on LBP Research in Primary Care (Denmark 17-19 October 2012).Objective. To evaluate the utility of the model in reference to rising rates of back pain related disability, by identifying a) the most promising avenues for future research in biological, psychological and social approaches, b) promising combinations of all three approaches and c) obstacles to effective implementation of biopsychosocial based research and clinical practice.Summary of Background Data. The biopsychosocial model of back pain has become a dominant model in the conceptualisation of the aetiology and prognosis of back pain, and has led to the development and testing of many interventions. Despite this back pain remains a leading source of disability worldwide.Methods. The review is a synthesis based on the plenary sessions and discussions at the XII International Forum on LBP Research in Primary Care. The presentations included evidence-based reviews of the current state of knowledge in each of the three areas (biological, psychological and social), identification of obstacles to effective implementation and missed opportunities, and identification of the most promising paths for future research.Results. While there is good evidence for the role of biological, psychological and social factors in the aetiology and prognosis of back pain, synthesis of the three in research and clinical practice has been suboptimal.Conclusion. The utility of the biopsychosocial framework cannot be fully assessed until we truly adopt and apply it in research and clinical practice.

ABSTRACT: Inconsistent reporting of outcomes in clinical trials of patients with non-specific low back pain (NSLBP) hinders comparison of findings and the reliability of systematic reviews. A core outcome set (COS) can address this issue as it defines a minimum set of outcomes that should be reported in all clinical trials. In 1998, Deyo et al. recommended a standardized set of outcomes for LBP clinical research. The aim of this study was to update these recommendations by determining which outcome domains should be included in a COS for clinical trials in NSLBP. An International Steering Committee established the methodology to develop this COS. The OMERACT Filter 2.0 framework was used to draw a list of potential core domains that were presented in a Delphi study. Researchers, care providers and patients were invited to participate in three Delphi rounds and were asked to judge which domains were core. A priori criteria for consensus were established before each round and were analysed together with arguments provided by panellists on importance, overlap, aggregation and/or addition of potential core domains. The Steering Committee discussed the final results and made final decisions. A set of 280 experts was invited to participate in the Delphi; response rates in the three rounds were 52, 50 and 45 %. Of 41 potential core domains presented in the first round, 13 had sufficient support to be presented for rating in the third round. Overall consensus was reached for the inclusion of three domains in this COS: 'physical functioning', 'pain intensity' and 'health-related quality of life'. Consensus on 'physical functioning' and 'pain intensity' was consistent across all stakeholders, 'health-related quality of life' was not supported by the patients, and all the other domains were not supported by two or more groups of stakeholders. Weighting all possible argumentations, the Steering Committee decided to include in the COS the three domains that reached overall consensus and the domain 'number of deaths'. The following outcome domains were included in this updated COS: 'physical functioning', 'pain intensity', 'health-related quality of life' and 'number of deaths'. The next step for the development of this COS will be to determine which measurement instruments best measure these domains.European Spine Journal 04/2015; DOI:10.1007/s00586-015-3892-3 · 2.47 Impact Factor

ABSTRACT: Nonspecific persistent and chronic low back pain (LBP) is one of the world's most significant burdens. Its management continues to be challenging despite advancements in medical diagnostics and therapeutics. The purpose of this narrative review is to update evidence-based, multidisciplinary assessment and treatment strategies for nonspecific non-acute LBP with special emphasis on the growing influence of psychological principles in physiotherapists' (PT) practice. An electronic literature search was performed to identify relevant clinical practice guidelines, from which an overarching summary was synthesized. All guidelines were consistent in their recommendations for the assessment of psychosocial factors and psychology-based interventions. In discussion, we underlined psychological processes and psychology-based strategies that are clinically relevant to, and within the professional competency and scope of PT practice.12/2014; 29(1):21-28.

ABSTRACT: There is a strong tradition of performing a clinical examination of low back pain (LBP) patients and this is generally recommended in guidelines. However, establishing a pathoanatomic diagnosis does not seem possible in most LBP patients and clinical tests may potentially be more relevant as prognostic factors. The aim of this review of the literature was to systematically assess the association between low-tech clinical tests commonly used in adult patients with acute, recurrent or chronic LBP and short- and long-term outcome. MEDLINE, Embase, and MANTIS were searched from inception to June 2012. Prospective clinical studies of adult patients with LBP with or without leg pain and/or signs of nerve root involvement or spinal stenosis, receiving non-surgical or no treatment, which investigated the association between low-tech clinical tests and outcome were included. Study selection, data extraction and appraisal of study quality were performed independently by two reviewers. A total of 5,332 citations were retrieved and screened for eligibility, 342 articles were assessed as full text and 49 met the inclusion criteria. Due to clinical and statistical heterogeneity, qualitative synthesis rather than meta-analysis was performed. Associations between clinical tests and outcomes were often inconsistent between studies. In more than one third of the tests, there was no evidence of the tests being associated with outcome. Only two clinical tests demonstrated a consistent association with at least one of the outcomes: centralization and non-organic signs. For most clinical tests in LBP there is not consistent evidence for an association with outcome. Centralization and non-organic signs are exceptions from that. None of the other clinical tests have been investigated in confirmatory studies and study quality is generally low. There is a need for hypothesis testing studies designed specifically to investigate the prognostic value of the clinical tests, and a need for standardization of the performance and interpretation of tests.12/2015; 23(1).
