“…The three investigated performance tests have been reported to display good discriminative ability and high reliability [4,20,28,32,34,36,43]. This is in accordance with our results: the control group presented significantly higher outcome values in all performance tests, indicating good discriminative ability of these tests.…”

The value of physical performance tests for predicting therapy outcome in patients with subacute low back pain: a prospective cohort study

Considering the enormous costs of intensive multidisciplinary treatment, predictive tests for therapy outcome are needed to evaluate patients' performance potential and increase cost effectiveness. Somatic parameters are commonly used to evaluate health status and serve as an additional means of forecasting the prognosis, yet little is known of their validity. In this study, we investigated the prognostic value of somatic parameters regarding the outcome of multidisciplinary treatment in patients with subacute low back pain. The study was designed as a prospective cohort study of 162 patients. Somatic parameters were assessed with three physical performance tests (Villiger test, Oesch test, Biering-Sørensen test) before treatment (T0), after 3 weeks' inpatient therapy (T1) and at 6-month follow-up (T2). Psychometric characteristics of subjective pain perception (VAS), a pain disability index (PDI) and a physical capability index (FFbH-R) were recorded. Correlation coefficients between the physical performance test scores and psychometric characteristics were calculated. To predict therapy outcome, discriminant analyses were performed. A control group (n = 30) was evaluated at similar time points without receiving any therapy. Our results demonstrate good discrimination between patients and controls by means of the investigated performance tests and exhibit a significant negative correlation with the psychometric data. Lower outcome values at study entry correlated with higher pain intensity and disability after multidisciplinary treatment. However, the statistical magnitude of correlation was relatively low and further discriminant analysis did not reveal any predictive value. Consequently the physical performance tests do not have a prognostic value regarding therapy outcome.

“…There is a growing body of evidence for association between paraspinal muscles degeneration and LBP. In several imaging studies, LBP has been investigated in relation to paraspinal muscle CSA [1,6,12,14,16,28,41,47,48,52], MRI signal intensity [10], and fat infiltration [1,6,12,14,19,21,23,28,32,41,47,52]. In patients with chronic LBP, studies consistently show a decrease in CSA [6,12,23], which may reach 10% compared to healthy individuals [19].…”

“…Again these changes were localized to the level of injury and were associated with rapid changes in intra-muscular fat. Several studies evaluated the association between CT-evaluated paraspinal muscles density and LBP [14,15,19,28,29,34,40]. Muscle density is an expression of degeneration of the muscles and reflects the number of muscle fibers, the area of the individual muscle fiber, and the packing of the contractile material [22], whereas the CSA is mainly determined by the total number of muscle fibers, to a lesser degree, the size of the fibers [35,36], and the quantity of fat in the muscle [6,9].…”

“…Reduced size of multifidus has also been reported in acute LBP [16] and recent animal work has shown rapid changes in CSA in the multifidus muscle following discrete injury to an intervertebral disc [17]. In several imaging studies, chronic LBP was found to be associated with CT-evaluated muscle density (measured in Hounsfield units) [14,19,28]. Despite the range of studies that have investigated the association between back pain and muscle changes, none has aimed to relate muscle changes to specific radiologically identified pathology of the spine.…”

Changes in paraspinal muscles and their association with low back pain and spinal degeneration: CT study

et al. 2009

The objectives of the study were to evaluate the association between lumbar paraspinal muscle density, evaluated on computed tomography (CT) and age, sex and BMI; and to evaluate the association of those changes with low back pain (LBP) and spinal degeneration features in a community-based sample. This study was an ancillary project to the Framingham Study. A sample of 3,529 participants aged 40-80 years had a CT scan performed to assess aortic calcification. 187 individuals were randomly enrolled in this study. LBP in the last 12 months was evaluated using self-report questionnaire. Density (in Hounsfield units) of multifidus and erector spinae was evaluated on CT. The prevalence of intervertebral disc narrowing, facet joint osteoarthritis (FJOA), spondylolysis, spondylolisthesis and spinal stenosis were also evaluated. We used linear regression models to examine the association of paraspinal muscles density with age, sex, BMI, LBP, and spinal degeneration features. The results show that in our study, men have higher density of paraspinal muscles than women, younger individuals have higher density than older ones and individuals with lower weight have higher muscle density than overweight. No differences between individuals with and without LBP were found. Significant association was found between L4 multifidus/erector spinae density and FJOA at L4-L5; between multifidus at L4 and spondylolisthesis at L4-5; and between erector spinae at L4 and L5 with disc narrowing at L4-5 and L5-S1, respectively. We conclude that the paraspinal muscle density decreases with age, and increases BMI. It is associated with at some levels FJOA, spondylolisthesis and disc narrowing at the same level, but not associated with occurrence of LBP.

“…6 It was anticipated that there would be a decrease in pain since muscle strength and density appear to be correlated with lumbar pain. 7 At the next visit the patient purchased a 65 cm Swiss Ball to aid in her rehabilitation program. The patient was taught the "fabulous five" exercises developed by Ierna.…”
