Randomized Controlled Trial Comparative Study Clinical Trial
Responsiveness of general health status in chronic low back pain: a comparison of the COOP charts and the SF-36.
The objective of this study was to compare the responsiveness and assess the concurrent validity of two functional health status instruments, the Dartmouth COOP charts and the SF-36 in chronic low-back pain (CLBP) patients. The data came from 129 of 174 patients who participated in a randomized clinical trial of the therapeutic management of CLBP. Reliable and valid disease-specific outcomes, patient-rated low-back pain and disability, were used as external criteria (EC) to identify improved and non-improved patients. ⋯ Six of the instruments' nine dimensions are moderately to highly correlated (r=0.52 to 0.86), and the overall canonical correlation was high (R=0.9). In conclusion, both instruments seem equally suitable for use as outcome measures in clinical trials on CLBP. The COOP charts are faster to fill out and score.

Objective. Treatment of pain associated with failed back surgery syndrome was evaluated in a pilot clinical study of a new dual lead spinal cord stimulation (SCS) system. Methods. ⋯ While external hardware problems occurred, 65% of dual lead SCS patients were willing to repeat the SCS implant procedure. Conclusions. Dual lead stimulation proved beneficial for patients with low back and leg pain associated with failed back surgery syndrome.

Review Comparative Study
Fear of movement/(re)injury, avoidance and pain disability in chronic low back pain patients.
Chronic pain syndromes such as chronic low back pain are responsible for enormous costs for health care and society. For these conditions a pure biomedical approach often proves insufficient. ⋯ The main assumption is that pain and pain disability are not only influenced by organic pathology, if found, but also by psychological and social factors. In this contribution, a behavioural analysis of chronic musculoskeletal pain will be discussed, with special attention to the role of pain-related fear in the development and maintenance of chronic pain disability, and the behavioural rehabilitation perspective of chronic pain management.

Randomized Controlled Trial Clinical Trial
Endurance training of the trunk extensor muscles in people with subacute low back pain.
Clinicians treating patients with low back pain often use exercise to reduce pain and improve function. The aim of this study was to evaluate the effectiveness of trunk extensor endurance training in reducing pain and decreasing disability in subjects with subacute low back pain (ie, onset of back pain within 7 days to 7 weeks). ⋯ Trunk extensor endurance training reduced pain and improved function at 3 weeks but resulted in no improvement at 6 weeks when compared with the control group. Endurance exercise is considered to expedite the recovery process for patients with an acute episode of low back pain.

A prospective analysis of the relative influence of pain-specific and performance-specific cognitive variables on lifting tasks using empirically derived measures. ⋯ Data suggest that what patients believed they could achieve accurately determined their actual spinal function, independent of their sense of control over pain or their distress. Approaches to low back disorders emphasizing perceived pain control as a central cognitive determinant of disability were unsupported.
