title: Novel spinal cord stimulation parameters in patients with predominant back pain.
abstract: OBJECTIVE
  To examine the feasibility of novel high-frequency spinal cord stimulation therapy in a cohort of patients with chronic predominant back pain during a four day, percutaneous trial.
  
  
  METHODS
  Prospective, multicenter open label pilot trial.
  
  
  METHODS
  Twenty-four patients with back pain greater than leg pain who were candidates for spinal cord stimulation were trialed at five U.S. centers.
  
  
  METHODS
  Patients completed a percutaneous trial with a commercially available spinal cord stimulator. The implanted leads were then connected to the novel external stimulation device and patients were trialed for an additional four days.
  
  
  METHODS
  Pain intensity ratings, subjective descriptions, and patients' preference.
  
  
  RESULTS
  There was significant improvement from baseline in overall pain scores (8.68 to 2.03, [p < 0.001]) and back pain scores (8.12 to 1.88, [p < 0.001]) with the investigational stimulation. The investigational stimulation was preferred to the commercially available systems in 21 of 24 patients (88%).
  
  
  CONCLUSIONS
  Patients with predominant back pain reported a substantial reduction in overall pain and back pain when trialed with high-frequency spinal cord stimulation therapy.
