title: [Isokinetic and functional lumbar evaluation in workers pensioned with disability].
abstract: BACKGROUND
  there were 13,371 disability reports in Jalisco during 2008 about lumbar spine injuries; most of them were permanent and required evaluation of lumbar capabilities. The objective was to evaluate the functionality of the lumbar spine through the Oswestry questionnaire and isokinetic evaluation in pensioners with lumbar injury.
  
  
  METHODS
  a comparative study on 20 workers with disability status of lumbar injury was done. Isokinetic exercises to identify musculoskeletal capacity and the Oswestry questionnaire to know the percentage of disability were applied.
  
  
  RESULTS
  The Oswestry questionnaire showed 60 % average on lumbar spine functionality. A peak torque average was 44 Nw on the assessing isokinetic extension. Mean and mode of zero in fatigue at work were estimated. The flexion peak torque was -75.5 Nw. The average and mode power were 40 V. Both the mean and mode work fatigue were zero.
  
  
  CONCLUSIONS
  Isokinetic evaluation was not normal in any of the workers, confirming disability status.
