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 .
Responsiveness of common outcome measures for patients with low back pain.
STUDY DESIGN A prospect i ve cohort study assessing the responsiveness of two disease-specific question naires and a generic health question naire for patients with low back pain and sciatica . OBJECTIVES To compare the responsiveness of the eight scales and two summery scales of the SF-36 question naire with that of the Oswestry Disability Index and Low Back Outcome Score question naires . SUMMARY OF BACKGROUND DATA Evaluation of treatment outcome is being determined more frequently from a patient 's perspective , particularly the impact treatment has on current health status . METHODS Patients were recruited from two orthopedic back pain clinics in a tertiary hospital . Patients completed the pretreatment question naire 1 month before treatment and follow-up question naires a minimum of 2 - 6 months after treatment . Patients undergoing surgery were also observed for a minimum of 2 years . RESULTS Overall , the Oswestry Disability Index was most responsive ; however , individual scales from the SF-36 question naire showed equal or greater sensitivity to change than the Oswestry Disability Index in each of the patient subgroups . The SF-36 Role Physical scale was prone to floor effects ( a high percentage of respondents score zero ) , and the change scores from the SF-36 Role Emotional scale varied by 100 points in either direction in each of the patient subgroups . CONCLUSION Responsiveness varied according to which method was used in its calculation . The responsiveness of the SF-36 question naire shows that it can be a useful adjunct in the assessment of patients with low back pain when combined with disease-specific question naires
