A prospective outcome study on the effects of facet joint radiofrequency denervation on pain, analgesic intake, disability, satisfaction, cost, and employment.
To assess the effect of radiofrequency denervation (RFD) on patients with chronic low back pain (LBP) of facet joint origin. ⋯ RFD provides safe and significant short-term improvement in pain, analgesic requirements, function, satisfaction, and direct costs in patients with chronic LBP of facet origin.

Changes in the mechanical properties of the trunk in low back pain may be associated with recurrence.
Exercise is one of the few effective treatments for LBP. Although exercise is often based on the premise of reduced spinal stiffness, trunk muscle adaptation may increase stiffness. This study developed and validated a method to assess trunk stiffness and damping, and tested these parameters in 14 people with recurring LBP and 17 pain-free individuals. ⋯ Estimates were reliable and validated by accurately estimated mass. Contrary to clinical belief, trunk stiffness was increased, not reduced, in recurrent LBP, most likely due to augmented trunk muscle activity and changes in reflex control of trunk muscles. Although increased stiffness may aid in the protection of spinal structures, this may have long-term consequences for spinal health and LBP recurrence due to compromised trunk dynamics (decreased damping).

Do lumbar stabilising exercises reduce pain and disability in patients with recurrent low back pain?
Does a graded exercise program emphasising lumbar stabilising exercises reduce pain and disability at 12 months, compared with a walking program, for patients with recurrent low back pain? ⋯ Lumbar stabilising exercises appear to have a similar effect on pain and disability for patients with recurrent low back pain as a daily walking program.

Clinical TrialDoes physical activity change predict functional recovery in low back pain? Protocol for a prospective cohort study.
Activity advice and prescription are commonly used in the management of low back pain (LBP). Although there is evidence for advising patients with LBP to remain active, facilitating both recovery and return to work, to date no research has assessed whether objective measurements of free living physical activity (PA) can predict outcome, recovery and course of LBP. ⋯ This research will investigate levels and changes in activity levels of an acute LBP cohort and the predictive relationship to LBP recovery. The results will assess whether occupational, psychological and behavioural factors affect the relationship between free living PA and LBP recovery. Results from this research will help to determine the strength of evidence supporting international guidelines that recommend restoration of normal activity in managing LBP.
