A systematic review. ⋯ There remains no standard PSLR procedure, no consensus on interpretation of results, and little recognition that a negative PSLR test outcome may be of greater diagnostic value than a positive one. The causal link between LBP pathology and hamstring action remains unclear. There is a need for research into the clinical use of the PSLR; its intra- and interobserver reliability; the influences of age, gender, diurnal variation, and psychosocial factors; and its predictive value in lumbar intervertebral disc surgery.

Comparative Study
Concurrent validity of questionnaire and performance-based disability measurements in patients with chronic nonspecific low back pain.
This study aimed to investigate the concurrent validity of two approaches to disability measurement in patients with chronic nonspecific low back pain (CLBP). It was hypothesized that if both are measuring the same construct, the instruments would lead to similar disability results and would correlate strongly (r > 0.75). The study compared the results of self-reported and performance-based measures of disability in 64 consecutive patients with CLBP. ⋯ In contrast the results from the performance-based measures suggested that the subjects should be able to work at a physical intensity level of moderate to heavy. Little to moderate correlation was observed between the self-report and performance-based measures (Spearman rank correlations: Roland-FCE (-0.20), p > 0.05; Oswestry-FCE (-0.52), p < 0.01; Quebec-FCE (-0.50), p < 0.01). Results are interpreted to suggest that both performance-based and self-report measures of disability should be used in order to obtain a comprehensive picture of the disability in patients with CLBP.

Randomized Controlled Trial Clinical Trial
Treatment of chronic lower back pain with lumbar extension and whole-body vibration exercise: a randomized controlled trial.
A randomized controlled trial with a 6-month follow-up period was conducted. ⋯ The current data indicate that poor lumbar muscle force probably is not the exclusive cause of chronic lower back pain. Different types of exercise therapy tend to yield comparable results. Interestingly, well-controlled vibration may be the cure rather than the cause of lower back pain.

Randomized Controlled Trial Clinical Trial
Randomised study of long term outcome after epidural versus non-epidural analgesia during labour.
To determine whether epidural analgesia during labour is associated with long term backache. ⋯ After childbirth there are no differences in the incidence of long term low back pain, disability, or movement restriction between women who receive epidural pain relief and women who receive other forms of pain relief.

Review Comparative Study
The cochrane review of advice to stay active as a single treatment for low back pain and sciatica.
A systematic review was conducted within the Cochrane Collaboration Back Review Group. ⋯ The best available evidence suggests that advice to stay active alone has little beneficial effect for patients with acute, simple low back pain, and little or no effect for patients with sciatica. There is no evidence that advice to stay active is harmful for either acute low back pain or sciatica. Because there is no considerable difference between advice to stay active and advice for bed rest, and there are potential harmful effects of prolonged bed rest, it is reasonable to advise people with acute low back pain and sciatica to stay active. These conclusions are based on single trials.
