title: New modified english and hindi oswestry disability index in low back pain patients treated conservatively in Indian population.
abstract: METHODS
  Prospective cohort study along with questionnaire.
  
  
  OBJECTIVE
  To measure the correlation of the visual analogue score (VAS), with (Oswestry disability Index [ODI], version 2.1a) in English, and modified ODI (English and Hindi version). To validate translated version of the modified ODI in English version to Hindi.
  
  
  BACKGROUND
  Conflicting evidence in literature regarding the ability for existing ODI score to accurately measure the pain associated disability.
  
  
  METHODS
  One hundred and three patients conservatively treated for low back pain were enrolled in the study. The Pearson correlation coefficient for VAS and ODI along with the Cronbach α and test-retest reliability for Hindi version using the intraclass correlation coefficient was recorded. The new proposed translated Hindi version of ODI was carried out with established guidelines.
  
  
  RESULTS
  The mean age in English and Hindi version of ODI was 53.5 years and 58.5 years, respectively. The gender ration was 21:24 in the English version and 35:23 in the Hindi version. The mean follow-up in English and Hindi version of ODI was 3.4 months and 50.27 months, respectively. The Cronbach coefficient α=0.7541 for English ODI and 0.9913 for Hindi ODI was recorded for the both modified versions.
  
  
  CONCLUSIONS
  The new modified ODI is time saving and accurate, and it avoids the need to measure other scores and has stronger correlation with VAS score compared to the previous scores. We recommend this version for both English and Hindi speaking population as an assessment tool to measure the disability related to pain.
