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 .
Cross-Cultural Adaptation of the Lumbar North American Spine Society Questionnaire for Italian-Speaking Patients With Lumbar Spinal Disease
Study Design . A cross-cultural adaptation and cross-sectional study of a sample of lumbar spine patients , with a sub sample followed prospect ively for retest reliability . Objectives . To assess the Italian version instrument reliability and validity . Summary of Background Data . The orthopaedic outcome measurements have been usually focused on objective parameters as radiograph measures or other technical aspects . However , these parameters are weakly related with outcomes that are more relevant to patients as functional status and symptoms . In the last ten years , the patient-oriented measures have become an important aspect of spinal clinical outcome evaluation . The most common instruments to assess patient perspective are self-administered question naires that must be vali date d by a widely accepted process to evaluate reliability and validity , which are fundamental for every instrumental measure . Methods . The North American Spine Society ( NASS ) question naire was culturally adapted for Italian-speaking people following the Guillemin criteria . The Italian version was tested on 74 consecutive patients who were referred to the authors ’ department and suffered from low back pain with leg irradiation . The results were compared with other vali date d patient-oriented measures . Forty-eight-hour retests were performed on a sub sample of 45 patients . Results . The question naire was favorably accepted by patients . The lumbar spine pain and disability and neurogenic symptoms subscales showed a high correlation with other patient-oriented measures , as hypothesized , and it also showed good values on test-retest . Conclusions . The question naire should be considered for patient health status monitoring and for clinical trials
