Clinical Legacy of Capacitive Coupling

Capacitive coupling is FDA-approved as a safe and effective therapeutic signal that has been prescribed clinically for over two decades.

Years of
Clinical Use

More Likely to Have a
Successful Outcome1

Reduction in
Failure Rates2

Proven in a Level 1 Clinical Trial...

The spine fusion therapy delivered by ActaStim-S was evaluated in a prospective, randomized, double-blind, multi-center clinical study of 215 evaluable patients:

  • Primary fusion of all types, 1 or 2 levels
  • Endpoints were radiographic and clinical success
  • Clinical success required resumption of activities, limited pain and minimal medication use

... Across Multiple Patient Types1

As assessed 12 months after surgery, patients who use the same proven therapy delivered by ActaStim-S were 2.3 times more likely to achieve overall success with 9 months of treatment, regardless of:

  • Type of fusion
  • Prior history of surgery
  • Smoking status

Guide Their Journey in the Right Direction

After surgery, time with your patient becomes more limited, while the path to healing becomes more important. The ActaStim Sync companion app can be there when you can’t, gathering an unparalleled level of data on your patient’s progress.

Key App Features

Daily usage and activity level tracking shows patients their progress over time.

Real-time pain level logging reduces reliance on patient recollection.

What Prescribers May Want to Know

Will I have access to the data my patients collect with the ActaStim Sync App?

Yes. Your local Theragen representative can provide you with reports, and patients may also present ActaStim Sync summary data directly from their phone during follow-up appointments.

How are my patients fitted with ActaStim-S, and how do they learn to use the digital app?

First, your dedicated Theragen representative will meet with patients to go over how to set up and use Actastim-S. At this same time, your representative will help them download the digital app, sync the app to the device, and review how to use the app on their phone to get them started.

When can patients start wearing the ActaStim-S device after lumbar spine fusion surgery?

At the surgeon’s discretion, most surgical approaches are compatible with starting a patient’s spine stimulator therapy anytime from immediately post-op to two weeks post-op. However, it is essential to note that electrodes should not be placed directly over unhealed incisions.

How much does ActaStim-S cost the patient?

The patient’s insurance plan dictates the patient’s financial responsibility. Our reimbursement experts will assist with all payor submissions, and if for some reason reimbursement is not available, we can customize a payment plan to make the device affordable. Theragen will explore numerous options to help patients receive the care they need.
