The ODI remains a valid and vigorous measure and has been a worthwhile outcome measure .
The behavior of the instrument is incompletely understood , particularly in sensitivity to real change .
The Oswestry Disability Index ( ODI ) has become one of the principal condition-specific outcome measures used in the management of spinal disorders .
To review the versions of this instrument , document methods by which it has been vali date d , collate data from scores found in normal and back pain population s , provide curves for power calculations in studies using the ODI , and maintain the ODI as a gold st and ard outcome measure .

Low Back Pain Rating scale: validation of a tool for assessment of low back pain
Low Back Pain Rating scale is an index scale which includes measurements of pain intensity , disability , and physical impairment . The scale was design ed to monitor the outcome of clinical trials of low back pain treatment . It has been vali date d in 58 patients following first-time discectomy .  The scale rating can be rapidly carried out and requires no special aids . With slight modification it can be used in office and telephone interviews , as well as postal question naires . These modifications only slightly reduce the quantity of information gathered . In the study , a high rater agreement ( 97.7 % ) was found without level difference between two observers using the scale . The validation process included : construct validity , criterion-related validity and item bias , relative to Global Assessment s pronounced by the patient and an experienced clinician . Low Back Pain Rating scale hs been shown to be valid and reliable in the assessment of low back pain
