Background and study aims
Spinal cord stimulation (SCS) involves implanting a device that delivers small electrical fields to the spinal cord to provide pain relief in patients with chronic (long-term), intractable (hard to control) back and leg pain. Significant leg pain relief has been reported with traditional SCS which uses a low frequency (<1200 Hz), but there is limited long-term data supporting the use of low-frequency SCS in predominant back pain patients. Recent studies testing SCS using a frequency of 10 kHz (HF10 Therapy™) have shown that this treatment is effective and safe in patients with both back and leg pain. The results from these studies demonstrated that these patients had significant pain relief up to 24 months. The decreased pain in both back and leg were consistent throughout the studies with improvements in functional capacity with no perception of paresthesia (a burning or prickling sensation). The aim of this study is to test the performance of HF10 therapy with the surgical lead worldwide in patients with back and/or leg pain, as per centers’ routine practice.
Who can participate?
Patients aged over 18 with chronic, intractable back and/or leg pain
What does the study involve?
Participants undergo Spinal Cord Stimulation (SCS) at 10 kHz (HF10 therapy) as per the center’s usual practice. SCS involves the surgical placement of a surgical lead (which looks like a thin wire) into a small area near the spinal cord. Electrical stimulation is delivered through this wire by a small, battery-operated, rechargeable SCS implanted generator. Each patient is followed for 12 months after device activation. The participants attend regular clinic visits to complete questionnaires and to provide feedback on their pain. Successfully treated participants get a permanent device implanted as per the center’s routine clinical practice.
What are the possible benefits and risks of participating?
Participants may benefit from the SCS system to relieve their pain. There are no direct risks of taking part in this study, although the general risks of having a spinal stimulation device in place apply.
Where is the study run from?
Up to 40 pain centers in the USA and Europe
When is the study starting and how long is it expected to run for?
October 2018 to December 2021

| Scientific title | A prospective observational multicenter study of HF10 therapy using surgical leads |
| Study acronym | SURPASS |
| Study objectives | The purpose of this study is to assess the clinical performance of HF10 therapy delivered to the spinal cord through SURPASS™ surgical leads in subjects with chronic, intractable, back and/or leg pain of neuropathic origin. |

| Health condition(s) or problem(s) studied | Chronic, intractable, back and/or leg pain of neuropathic origin |
| Intervention | As part of their standard care, participants undergo a trial (temporary evaluation period) of Spinal Cord Stimulation (SCS) at 10 kHz (HF10 Therapy) as per the center’s usual practice and following this, those for whom the trial treatment was successful have a permanent device implanted as per center’s routine clinical practice. Following device activation, participants are followed for a period of 12 months. The participants attend regular clinic visits, at 3, 6 and 12 months, to complete questionnaires, and to provide feedback on their pain, quality of life, disability, health status, satisfaction and work status. At these visits, the physicians will take assessments from the participants such as pain evaluation, medication usage and side effects (if any). |
