title: [Application analysis of patient reported outcome scale for low back and leg pain].
abstract: OBJECTIVE
  To explore the reliability ,validity and reaction degree of patient reported outcome scale for low back and leg pain.
  
  
  METHODS
  Two hundreds inpatients were analyzed between August 2010 and January 2012, including 93 males and 107 females with an average age of 50.3 years old ranging from 22 to 65 years. There were 144 cases of lumbar disc herniation and 56 of lumber spinal stenosis. All patients were tested by the patient reported outcome scale for low back and leg pain, and then analyzed the reliability,validity and reaction degree of the scale.
  
  
  RESULTS
  There was no statistical significence difference (P>0.05) and significant correlation (r>0.9) in scores of two times in patients with no change in illness. Measurement result of the scale had significant correlation (r>0.9) with Oswestry disability index (ODI). The total Cronbach's Alpha of the instrument was 0.931, the total split-half reliability was 0.912. The KMO value was 0.919, Bartlett test value was 1882.975 (P<0.001), factor analysis resulted in 3 factors with eigenvalue >1 which contributed to 64.364%. Scores of two times of 43 cases who felt better were 34.80+/-9.00 and 28.77+/-8.73, respectively,with stasitical significance (P<0.01).
  
  
  CONCLUSIONS
  The scale has a good reliability, validity and reaction degree,which can be applied for the therapeutic evaluation of low back and leg pain.
