What is a bone growth stimulator?

The ActaStim-S is a non-invasive stimulator technology designed to help you heal after spine fusion surgery. It generates a sensation-free electrical signal that helps boost your body’s own bone-healing processes.

It’s all about calcium ions!

Preclinical studies suggest that electrical stimulation can help the body recruit and use calcium ions to promote bone growth – and a successful fusion.2
The signal that ActaStim-S sends to your fusion site helps mimic this natural process by helping cells take in more calcium ions. Those ions then help support more bone cell growth.2,3

Your wear time

When the electrodes are placed on your skin, the device will activate and automatically start to record wear time. You and your care team will be able to monitor this information, along with your pain scores, to ensure you are getting the most out of your prescribed therapy.

of the way

Your ActaStim System comes with a dedicated representative who will help you set up and use the system, answer all your questions, and provide ongoing support throughout your entire healing journey.
We’ll even help you with insurance claims and payment plans if needed — because you should be focused on healing, not paperwork.

Have more questions?

Here are a few things other ActaStim patients frequently want to know.
The ActaStim-S therapeutic signal activates healing on a cellular level, so you will not notice any sensation at all. As long as the ultra-thin electrodes are applied to your back and a green checkmark is displayed, ActaStim-S is working!
What does ActaStim-S therapy feel like?
ActaStim-S is designed to deliver continuous therapy throughout the day. The key to providing effective treatment is consistency throughout your day and for the length of time specified by your doctor. In summary, the more you wear it, the better it works.2
How often should I wear the ActaStim-S device?
Disconnect the ActaStim-S device during bathing, showering, or swimming. Reconnect it as soon as possible after these activities. Remove the electrodes or place shower covers over them while showering. Ensure the silver pins are completely dry before reconnecting them to the generator cable to resume treatment, as the electrode wires will remain exposed. Never submerge the ActaStim-S device in water.
What should I do when I shower, bathe, or swim?

Yes, you can travel with your ActaStim device without any concerns. As it is a medical device, there are no issues with bringing it through TSA.

We advise carrying the device in its carrying case while going through the scanner. Alternatively, if you choose to wear the device, ask for a private screening and it's a good idea to bring the Instructions for Use (IFU) to address any questions that TSA staff may have.
