A reliability study was performed. ⋯ The ODI was highly reliable. The questions about work, back satisfaction, and pain medication showed good agreement. The GFS, pain intensity, fear-avoidance beliefs, and life satisfaction appeared to lack sufficient reliability to be recommended in postal questionnaires.

Clinical Trial Controlled Clinical Trial
Lumbar paraspinal muscle function, perception of lumbar position, and postural control in disc herniation-related back pain.
A follow-up study evaluating postural control, lumbar movement perception, and paraspinal muscle reflexes in disc herniation-related chronic low back pain (LBP) before and after discectomy. ⋯ The results demonstrate impaired lumbar proprioception and postural control in sciatica patients. During short-term follow-up after operative treatment, postural control does not seem to change, but impaired lumbar proprioception and feed-forward control of paraspinal muscles seem to recover.

Comparative StudyCircumferential and posterolateral fusion for lumbar disc disease.
Clinical outcome of low back fusion is unpredictable. There are various reports discussing the merits and clinical outcome of these two procedures. The patients were selected from a population of patients who had chronic low back pain unresponsive to conservative treatment. ⋯ The posterolateral fusion group had a 63.9% satisfactory outcome and the posterior lumbar interbody fusion group had an 80% satisfactory outcome using the Oswestry disability index for postoperative assessment. There was 61.1% improvement in working ability in the posterolateral fusion group and 77.1% improvement in the posterior lumbar interbody fusion group which was not statistically significant. The authors consider instrumented circumferential fusion with posterior lumbar interbody fusion better than instrumented posterolateral fusion for managing chronic disabling low back pain.

Review
Low back pain: what is the long-term course? A review of studies of general patient populations.
It is often claimed that up to 90% of low back pain (LBP) episodes resolve spontaneously within 1 month. However, the literature in this area is confusing due to considerable variations regarding the exact definitions of LBP as well as recovery. Therefore, the claim--attractive as it might be to some--may not reflect reality. ⋯ The risk of LBP was consistently about twice as high for those with a history of LBP. The results of the review show that, despite the methodological variations and the lack of comparable definitions, the overall picture is that LBP does not resolve itself when ignored. Future research should include subgroup analyses and strive for a consensus regarding the precise definitions of LBP.

Reliability and ease of use of the Itrel 3 System (Medtronic Inc., Minneapolis, MN) were prospectively assessed over 5 years in patients with a range of pain syndromes (mainly low back and/or leg pain, or ischemic pain due to peripheral vascular disease). The longevity of the implantable pulse generator (IPG) battery, the frequency with which system settings were changed, and the ease of use of the EZ patient programmer were assessed. Data on adverse events, pain relief, and patient satisfaction with therapy were also collected. ⋯ The intensity and duration of pain were reduced significantly and patient satisfaction with therapy was high. We conclude that the Itrel 3 System performed well over 5 years and was easy to use. Its safety and effectiveness for the relief of chronic intractable pain of the trunk or limbs were also confirmed.
