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 .

[Active music therapy for chronic pain: a prospective study].
There are only few publications about the effect of music therapy on pain relief . The intention of this prospect i ve study is to demonstrate the influence of the Nordoff/Robbins method of active music therapy in a group of 12 patients with fibromyalgia , myofascial pain syndromes and polyarthritis on  pain reduction , life quality and coping . The clinical parameters of each patient were related to the observations in the audio- and video-documented music therapy setting s and to the self-reported changes in pain intensity and pain behaviour . There was a significant reduction of pain intensity and pain-related disability in the music group compared to a control group , but no change in the depression and anxiety score . The influence of music therapy could be even better demonstrated in the systematic analysis of the single cases by individual profiles . Active music therapy affects especially the communicative and emotional dimension of chronic pain . Psychophysiological and psychodynamic models are presented to explain the effectiveness of music therapy on pain reduction . Clinical studies on music therapy as well as on other " art therapies " should relate the analysis of clinical parameters to the descriptive-phenomenological documentation of the therapeutic process to demonstrate systematic ally the influence of music and art in the individual case
