title: Efficacy of low power laser therapy and exercise on pain and functions in chronic low back pain.
abstract: OBJECTIVE
  The aim of this study was to determine whether low power laser therapy (Gallium-Arsenide) is useful or not for the therapy of chronic low back pain (LBP).
  
  
  METHODS
  This study included 75 patients (laser + exercise-25, laser alone-25, and exercise alone-25) with LBP. Visual analogue scale (VAS), Schober test, flexion and lateral flexion measures, Roland Disability Questionnaire (RDQ) and Modified Oswestry Disability Questionnaire (MODQ) were used in the clinical and functional evaluations pre and post therapeutically. A physician, who was not aware of the therapy undertaken, evaluated the patients.
  
  
  RESULTS
  Significant improvements were noted in all groups with respect to all outcome parameters, except lateral flexion (P < 0.05).
  
  
  CONCLUSIONS
  Low power laser therapy seemed to be an effective method in reducing pain and functional disability in the therapy of chronic LBP.
