title: Evaluation of systems of grading of neurological deficit in tuberculosis of spine.
abstract: METHODS
  Prospective comparative study.
  
  
  OBJECTIVE
  To compare the efficacy of the ASIA scoring system and Tuli's classification for assessment of neurological status in a typical case of Pott's paraplegia/tetraplegia and suggest a suitable classification.

  METHODS
  A total of 33 cases of tuberculosis of the spine with paraplegia were evaluated serially for the severity of the neurological deficit by grading systems as suggested by Tuli and ASIA score, during the course of treatment. A total of 111 readings of neurological status were recorded and analysed.
  
  
  RESULTS
  Tuli's grading was found to be sensitive for detection of early stage (grade I) of neurological deficit. The rest of the grades (grade II, III, IV) of Tuli's classification have a wide range of sensory-motor deficit and hence are insensitive to early detection of any deterioration/improvement in the neurological status. The ASIA score failed to grade all types of neurological deficit associated with the Pott's spine. The sensory-motor score obtained by the ASIA scale depends on the level of involvement of the spinal cord. The higher the level of the cord damage, the poorer is the score.
  
  
  CONCLUSIONS
  Neither Tuli's grading nor the ASIA scale alone can effectively grade all stages of neurological deficit in tuberculosis of the spine. The neurological deficit in tuberculosis of the spine should be described in stages and each stage should have sensory and motor scoring. A new staging system of Pott's tetraplegia/paraplegia is suggested.
