Randomized Controlled Trial
Predictive factors for 1-year and 5-year outcome for disability in a working population of patients with low back pain treated in primary care.
Many patients seeking primary care for low back pain continue to report disability several years after their initial visit. The aims of this study were to assess the independent predictive value of a number of potential predictive factors for disability at the 1-year and 5-year follow-ups, and to examine whether prediction models were improved by replacing baseline health-state-related variables with corresponding variables after treatment. A further aim was to describe possible differences between those on sick leave, early retirement or disability pension, and those who were not. ⋯ For those without disability the corresponding figure was 9% (n=8/92). Being a woman, duration of the current episode, similar problems during the previous 5 years, exercise level before the current episode, pain frequency at baseline, and disability after treatment emerged as predictive factors for disability at the 5-year follow-up. Replacing baseline health-state-related measures with corresponding measures after the treatment period, and adding physical-activity-related and possibly work-related factors might improve the likelihood of predicting future disability.

Comparative Study[Validity and reliability of Spinal Mouse to assess lumbar flexion].
To evaluate the validity and reliability of the Spinal Mouse model to assess lumbar spine flexion. ⋯ The Spinal Mouse has acceptable metrological properties to assess segmental and global lumbar mobility during trunk flexion. Its metrological properties are not acceptable to assess mobility of L5-S1.

The objective of our study was to investigate outcome predictors of short- and medium-term therapeutic efficacy of facet joint blocks. ⋯ Facet joint blocks appear to have a beneficial medium-term effect in one third of patients with chronic lower back pain and may therefore be a reasonable adjunct to nonoperative treatment. However, outcome appears to depend on clinical, not on morphologic, imaging findings.

(1) Chronic lumbar (lower back) pain, which affects many Canadians, imposes a large economic burden. (2) Symptoms may occur in the vertebral facet joints of 15% to 40% of patients with lower back pain. (3) Medial branch radiofrequency neurotomy is a minimally invasive outpatient procedure that reduces pain by interrupting the nerve supply to painful facet joints. (4) Four systematic reviews of this procedure offer disparate conclusions. (5) One small well designed observational study has shown positive results, but no equally rigorous randomized controlled trial has been conducted.
