BACKGROUND AND OBJECTIVE Magnetic resonance imaging (MRI) has the potential to identify pathology responsible for low back pain (LBP). However, the importance of findings on MRI remains controversial. We aimed to systematically review whether MRI findings of the lumbar spine predict future LBP in different samples with and without LBP. DATABASES AND DATA(More)
IMPORTANCE Existing guidelines and systematic reviews lack clear recommendations for prevention of low back pain (LBP). OBJECTIVE To investigate the effectiveness of interventions for prevention of LBP. DATA SOURCES MEDLINE, EMBASE, Physiotherapy Evidence Database Scale, and Cochrane Central Register of Controlled Trials from inception to November 22,(More)
OBJECTIVES To quantify and compare fitness levels of middle aged practitioners of soo bahk do (SBD; a Korean martial art similar to karate) with those of sedentary subjects. METHODS Eighteen volunteers, 14 men and four women (aged 40-60 years), participated. Nine sedentary subjects (mean age 46.7 years) and nine SBD practitioners (mean age 46.8 years)(More)
OBJECTIVE To investigate the influence of various weather conditions on risk of low back pain. METHODS We conducted a case-crossover study in primary care clinics in Sydney, Australia. A total of 993 consecutive patients with a sudden, acute episode of back pain were recruited from October 2011 to November 2012. Following the pain onset, demographic and(More)
BACKGROUND CONTEXT The clinical importance of lumbar pathology identified on magnetic resonance imaging (MRI) remains unclear. It is plausible that pathology seen on MRI is a risk factor for a recurrence of low back pain (LBP); however, to our knowledge, this has not been investigated by previous studies. PURPOSE The aim was to investigate whether lumbar(More)
BACKGROUND Most research on risk factors for low back pain has focused on long term exposures rather than factors immediately preceding the onset of low back pain. The aim of this study is to quantify the transient increase in risk of a sudden episode of low back pain associated with acute exposure to a range of common physical and psychological factors. (More)
OBJECTIVE To investigate a range of transient risk factors for an episode of sudden-onset, acute low back pain (LBP). METHODS This case-crossover study recruited 999 subjects with a new episode of acute LBP between October 2011 and November 2012 from 300 primary care clinics in Sydney, Australia. Each participant was asked to report exposure to 12(More)
To examine the prognosis and prognostic factors for patients with chronic low back pain presenting to a private, community-based, group exercise program. A total of 118 consecutive patients with chronic LBP were recruited. Baseline assessments included socio-demographic characteristics, back pain history and clinical examination findings. Primary outcome(More)
BACKGROUND The 6-minute walk test (6MWT) is widely used in clinical practice and research. Few studies have investigated activity level as a predictor of 6-minute walk distance (6MWD), and existing predictive models do not allow for activity level. OBJECTIVES To evaluate if knowledge of the level of physical activity enhanced the ability to predict 6MWD,(More)
Little is known about what triggers an episode of low back pain (LBP) in those presenting to primary care. Previous studies of risk factors have focused on specific occupational settings and work conditions. No study has asked primary care clinicians to consider what triggers an episode of sudden-onset LBP in patients presenting to them for care. The(More)
