Most of the outcome question naires had a mixed content reflecting various constructs such as pain and symptoms , sleep disturbances , psychological dysfunctions , physical impairments , and social functions .
STUDY DESIGN A systematic literature review of outcome question naires design ed for assessing functional status or disability in patients with low back pain .
OBJECTIVES To provide a comprehensive overview of all functioning/disability question naires used in recent years and to explore how the main concept(s ) was described or defined in the original paper , the content or the domains of disability , and the measurement properties of the question naires .
SUMMARY OF BACKGROUND DATA A number of clinical tools design ed for evaluating the functional status of patients with low back pain have been developed .
Only a few have been review ed earlier , and there has been little focus on the content reflected in the question naires .
Computed tomography findings 4 years after surgical management of lumbar spinal stenosis. No correlation with clinical outcome.
STUDY DESIGN A prospect i ve , cross-sectional study of the correlation between postoperative computed tomography findings and patients ' clinical outcomes approximately 4 years after laminectomy for lumbar spinal stenosis . OBJECTIVES To evaluate clinical and radiologic characteristics and their relation to each other . SUMMARY OF BACKGROUND DATA The goal of surgical management for lumbar spinal stenosis is to decompress the stenotic area determined in radiologic examinations to relieve pressure on the neurovascular structures . However , the success of this decompression very rarely has been confirmed by postoperative radiologic imaging or compared with clinical outcome . METHODS Postoperative computed tomography was performed on 191 patients . The findings were classified as " no stenosis , " " central stenosis , " " lateral stenosis , " or " central -lateral stenosis . " Postoperative instability of the lumbar spine was investigated by functional radiography . Clinical status was assessed by clinical examination . Subjective disability was assessing using the Oswestry question naire , and severity of pain using the visual analog scale . Walking capacity was evaluated by the tread-mill test . RESULTS Radiologic studies revealed postoperative stenosis  in 123 patients ( 64 % ) . Small differences between the computed tomography groups were shown for the Oswestry score , but not for walking distance . Clinical signs , severity of pain , and radiologic instability were very similar for all computed tomography groups . CONCLUSIONS Postoperative radiologic stenosis was very common in patients operated on for lumbar spinal stenosis , but this did not correlate with clinical outcome . The clinician must be cautious when reconciling clinical symptoms and signs with postoperative computed tomography findings in patients operated on for lumbar spinal stenosis
