A prospective observational study on the use of the Aberdeen Low Back Pain Disability Scale. ⋯ The Chinese version of the Aberdeen Low Back Pain Disability Scale retained the high levels of reliability, validity, and responsiveness of the original English version when tested in Hong Kong in four samples of Chinese patients with low back pain.

Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of active rehabilitation in chronic low back pain. Effect on pain intensity, self-experienced disability, and lumbar fatigability.
A randomized study comparing the results of active rehabilitation and passive control treatment in patients with chronic low back pain with follow-up at 6 months and 1 year. ⋯ The active progressive treatment program was more successful in reducing pain and self-experienced disability and also in improving lumbar endurance than was the passive control treatment. However, the group difference in lumbar endurance tended to diminish at the 1-year follow-up.

Comparative Study
The degree of decompressive relief and its relation to clinical outcome in patients undergoing surgery for lumbar spinal stenosis.
A cross-sectional, clinical study to evaluate surgical decompression of the stenotic area monitored by computed tomographic scan and its relation to clinical variables in patients operated on for lumbar spinal stenosis. ⋯ The satisfaction of the patients with the results of surgery was more important in surgical outcome than the degree of decompression detected on computed tomographic scan.

Comparative Study
Are anatomic landmarks reliable in determination of fusion level in posterolateral lumbar fusion?
Determination of the fusion level by direct observation and palpation of anatomic landmarks is compared with the finding obtained from a lateral intraoperative radiograph. ⋯ Determination of fusion level by direct observation and palpation of the anatomic landmarks is not reliable in patients who have had or require decompressive procedures. A lateral radiograph should be routinely obtained for accurate identification of the level to be fused.

Comparative Study
Radiation dose for pedicle screw insertion. Fluoroscopic method versus computer-assisted surgery.
Comparison of the radiation dose between the traditional fluoroscopic approach and computed tomography (CT)-based computer-assisted surgery for pedicle screw placement was determined. ⋯ Percutaneous pedicle screw insertion in the lumbar region of the spine, performed using fluoroscopic control, requires a lower radiation dose than do CT scans necessary for computer-assisted surgery. The CT radiation dose can be significantly decreased by optimization of the scanner settings for computer-assisted surgery. The advantages of computer-assisted surgery justify CT scans, when based on correctly chosen indications.
