Proven benefits

• Good to excellent long-term pain relief
  59% of 189 patients that included FBS, CRPS Type I and PVD sufferers reported good-to-excellent pain relief with a mean follow-up of 66 months (5.5 years) [1]
  
  

• 52% of 171 patients with a mean follow-up of up to 7 years had at least 50% sustained pain relief [2]
  
  

• A recent review suggests that SCS may produce substantial and long-lasting pain relief
  in 60-70% of CRPS patients [3]
  
  

• 78% of patients that included lumbosacral spine surgery failures (FBS), CRPS Type I and
  PVD sufferers, with a mean follow-up of 19 months, considered their outcome to be good
  or very good [4]

• Early treatment produces better results
  - Reducing the delay between spinal surgery and implantation to 3 years increases
     the success rate to 93%; increased from 9% in FBS patients who had >12 years
     delay between surgery and implantation [1]
  - Better results than re-operation in FBS patients who have not benefited from
     1 or more laminectomies [8]
  
  
• Enhanced performance of activities of daily living
  Improved sleep, increased ability to participate in social activities, reduction in
  analgesic use [5,2,6,7]

• Documented patient satisfaction
  Majority of patients would have SynergyT implanted again, would recommend
  it to others, and still use their system in a 5-year follow-up [8,4]

• Cost effective
  - SCS therapy reduces patients' needs for medical care, leading to cost savings
     over conservative treatment [9,10]
  - SCS treatment can pay for itself in 2.1 years (average 5.5 years) [9]
  - A cost-analysis model on CRPS SCS patients found substantial cost savings
     over a lifetime analysis vs physical therapy [11]

• Fewer side-effects
  Complications associated with implant are harmless and infrequent [5]
