Comparative Study Clinical Trial
Effects of chronic low back pain, age and gender on vertical spinal creep.
This study investigated the effect of chronic low back pain, age, gender, and time of measurement on the magnitude of vertical spinal creep (VSC) and its recovery. A mixed design, involving three independent variables (chronic low back pain, age, and gender) and one repeated variable (time), was used. One hundred and six subjects of both genders, with and without chronic low back pain, aged between 20 and 60 years, participated in the study. ⋯ A significant interaction was found between chronic low back pain and gender at the end of the unloaded phase (p=0.04). These findings suggest a combined influence of chronic low back pain, age, and gender on VSC and its recovery and that the dominance of each variable changed with the time of the measurement. Thus, subjects who differ in the presence of chronic low back pain, age, and gender should not be combined for statistical analysis of VSC and its recovery.

Comparative Study
Lumbar repositioning deficit in a specific low back pain population.
A cross-sectional observational design study was conducted to determine lumbar repositioning error in 15 subjects who had chronic low back pain with a clinical diagnosis of lumbar segmental instability and 15 asymptomatic participants. ⋯ The results of this study indicate that individuals with a clinical diagnosis of lumbar segmental instability demonstrate an inability to reposition the lumbar spine accurately into a neutral spinal posture while seated. This finding provides evidence of a deficiency in lumbar proprioceptive awareness among this population.

A population-based, incidence cohort study was conducted. ⋯ Low back pain is a common traffic injury with a prolonged recovery. Its incidence and prognosis are affected by multiple factors, including the type of compensation system. Our study suggests that biopsychosocial factors are important in determining prognosis.

Randomized Controlled Trial Clinical Trial
Intensive group training versus cognitive intervention in sub-acute low back pain: short-term results of a single-blind randomized controlled trial.
To evaluate the short-term effect of physical exercise and a cognitive intervention in low back pain. ⋯ Cognitive intervention improved disability and may be feasible for most patients sick-listed in the sub-acute phase. Physical exercise reduced patients' symptoms, but requires high motivation by patients. Despite positive effects in intervention groups on variables considered as negative prognostic factors for long-term disability and sickness absence, interventions had no effect on sick-listing.

ReviewIs low back pain part of a general health pattern or is it a separate and distinctive entity? A critical literature review of comorbidity with low back pain.
Research concerning the development of low back pain (LBP) has traditionally focused on risk factors in search of explanations. This review focuses on comorbidity as a first step in identifying a frail subpopulation with a higher risk of developing low back pain, in particular persistent low back pain. Research into comorbidity might yield a greater understanding of the underlying mechanism for low back pain. Data sources Medline was searched from the beginning of the data base to December 2000, followed by a search through the authors' personal collections of epidemiologic literature regarding low back pain. All articles written in English were included if they related LBP to at least one other physical disorder. Articles were excluded if the prevalence of such disorders could not be compared to that of a control group or to the expected prevalence in a normal population. Data extraction The retrieved articles were evaluated for quality based on predefined methodological criteria, whereupon information about associations between low back pain and other physical disorders was extracted. ⋯ The literature leaves no doubt that diseases cluster in some individuals and that low back pain is part of this pattern. However, the nature of the relationship between low back pain and other disorders is still unclear.
