Adherence to clinical guidelines produces greater improvement in disability in patients with low back pain (LBP), but a wide variation in physiotherapists' adherence has been documented repeatedly. The aim of the study was to investigate the adherence to National Clinical Guidelines for LBP among Danish physiotherapists with regard to three key guideline domains: 1) activity, 2) work, and 3) psychosocial risk factors. Additionally to investigate whether adherence differed between physiotherapists working in private clinics and physiotherapists working at public healthcare centres. A cross-sectional online survey was conducted with 817 Danish physiotherapists. Adherence to the three guideline domains was assessed using two vignettes. The difference in adherence between the groups was assessed using the chi-squared test.Background and purpose
Methods
MRI findings associated with spondyloarthritis (SpA) can be difficult to distinguish from the more prevalent findings of degeneration. Despite this, the two groups of MRI-findings are often evaluated in separate studies and in different study populations, which may reduce their applicability in daily clinical practice. The purpose of this study was to estimate the prevalence of degenerative and SpA related MRI-findings in the spine and sacroiliac joints (SIJ) in patients with persistent LBP. Patients with persistent LBP (n=1037, median age 33 [IQR 27–37], 54% women) referred to an outpatient, secondary care and non-surgical department were included in the study. MRI of the whole spine and the SIJ was performed and degenerative and SpA-related MRI-findings were evaluated by experienced musculoskeletal radiologists.Purpose and background:
Methods:
Sacroiliitis identified by MRI is considered as a keystone in the diagnosis of spondyloarthritis. To reduce the number of unnecessary MRI scans it would be ideal if sacroiliac (SI) joint pain provocation tests could be used to identify patients at risk of having sacroiliitis. The aim of the current study was to investigate the diagnostic value of three pain provocation SI-joint tests for sacroiliitis identified by MRI. Patients (n=454, mean age 32 years, 54% women) without clinical signs of nerve root compression were selected from a cohort consisting of patients with persistent low back pain referred to an outpatient spine clinic. Data from the Gaenslen's Test, Thigh Thrust Test and Long Dorsal Sacroiliac Ligaments Test and sacroiliitis identified by MRI were analysed.Purpose and background:
Methods:
To investigate the association between vertebral endplate signal changes (VESC) and low back pain (LBP). This prospective observational study included 344 persons (161 men and 183 women) sampled from the Danish general population. All participants had an MRI and filled in questionnaires at the age of 40 and again at the age of 44. The following LBP outcomes were used: “LBP past month,” “LBP past year,” and “non-trivial LBP”. The type and size of VESC at each endplate level were evaluated using a standardized evaluation protocol. Associations between VESC and LBP were investigated using logistic regression analysis.Purpose
Methods and materials
By systematic literature review, to quantify the association between vertebral endplate signal changes (VESC) and non-specific low back pain (NSLBP). MEDLINE, EMBASE, and SveMED databases were searched for the period 1984 to June 2009. Articles were included which investigated the association between VESC and NSLBP and reported sufficient data to construct two-by-two tables. Articles on specific low back pain conditions were excluded. A standardised data collection and quality assessment were performed. To estimate the association between VESC and NSLBP, two-by-two tables were created and exact odds ratios were calculated with 95% confidence intervals (CI). Meta-analysis was performed on homogeneous studies.Purpose
