title: Effects of whole body vibration therapy on main outcome measures for chronic non-specific low back pain: a single-blind randomized controlled trial.
abstract: OBJECTIVE
  The aim of this study was to determine whether a 12-week course of low-frequency vibrating board therapy is a feasible therapy for non-specific chronic low back pain, and whether it improves the main outcome measures.
  
  
  METHODS
  Randomized controlled trial.
  
  
  METHODS
  A total of 50 patients with non-specific low back pain were included. They were randomly assigned to either a vibrating plate via reciprocation therapy group (n = 25) or a control group (n = 25).
  
  
  METHODS
  The 12-week vibration therapy programme consisted of a total of 24 training sessions (2 times/week, with 1 day of rest between sessions). Assessments of the main outcome measures for non-specific low back pain were performed at baseline and at 12 weeks.
  
  
  RESULTS
  In the vibration therapy group there was a statistically significant improvement, of 20.37% (p = 0.031) in the Postural Stability Index (anterior-posterior); 25.15% (p = 0.013) in the Oswestry Index; 9.31% in the Roland Morris Index (p = 0.001); 8.57% (p = 0.042) in EuroQol 5D-3L; 20.29% (p = 0.002) in the Sens test; 24.13% (p = 0.006) in visual analogue scale back; and 16.58% (p = 0.008) in the Progressive Isoinertial Lifting Evaluation test.
  
  
  CONCLUSIONS
  A 12-week course of low-frequency vibrating board therapy is feasible and may represent a novel physical therapy for patients with non-specific low back pain.
