Take Part in a Movement

Are you receiving various treatments for your chronic knee pain and not seeing long-term results? You may be eligible to take part in Curonix’s Freedom-1 Study.

Peripheral Nerve Stimulation (PNS) has been gaining popularity in recent years as it is effective, safe and less invasive than surgery for the treatment of chronic pain.1 The Freedom-1 Study focuses on the use of our Freedom® Peripheral Nerve Stimulator (PNS) System to help relieve chronic pain and improve overall quality of life.

Freedom Stimulators are:

• Non-Drug, Non-Opioid

• Minimally-Invasive

• Typically, an Outpatient Procedure

• Full-Body Conditional at 1.5T MRI Scans*

Your Solution for Chronic Knee Pain Relief

We offer the Freedom PNS System with an implantable stimulator that helps relieve pain by sending electrical stimulation to a specific nerve near your knee, blocking the pain signals from reaching your brain. The system is designed to seamlessly integrate into your daily life and help you take control of your chronic pain.
Stimulation implant electrode, made by Curonix.
The implantable stimulator is intended to block pain signals to the brain, thereby helping to relieve chronic pain.
Peripheral Nerve Stimulation transmitter and assembly, made by Curonix.
Transmitter Assembly
(Transmitter + Antenna)
The external transmitter houses the battery and provides power to the antenna, which sends a signal through the skin to the implanted stimulator to help relieve pain.
Peripheral Nerve Stimulation Wearable, made by Curonix.
PNS Extremity
Our wearables hold the transmitter assembly. They are designed for comfort and should be worn over clothing.

What to Expect in The Freedom-1 Study

During your journey with the Freedom PNS System, your healthcare team will assess your pain levels and physical function through a series of scheduled appointments.

Here is an overview of what your journey might look like:

Ensuring you are the right candidate
Your healthcare professional will meet with you to ensure the Freedom PNS System is right for you and if you are eligible to be a part of the study.
Knee icon
Confirming Your Pain Location
To ensure we are treating the exact nerve that is causing your chronic pain, you will undergo a nerve block injection. This may provide immediate, temporary relief.
Calendar Icon
Trial Period
Experience the benefits of the Freedom PNS System firsthand during a trial period—helping assess the therapy’s effectiveness for both your physical and psychological well-being. During this time, in collaboration with your healthcare team, you will decide if this device is right for you.
Puzzle icon
Permanent Implant
Upon successful completion of the trial period, you will work together with your healthcare provider to discuss next steps. This includes coordination of your permanent implant procedure and how to use the Freedom PNS System, ensuring long-term support and care for your pain relief needs.

Please Note: If you choose to enroll, you will be a part of a double-blinded study. A double blinded study means you and your physician will not know which group you will be in until approximately 30 days after implantation. This helps eliminate bias and ensures reliable results.

Follow Up Appointments
Appointments with your healthcare professional will take place in-person at 1 week, 1 month, 3 months and 6 months after your permanent procedure. During these times, your healthcare provider will ask you a series of questions regarding your pain and functionality.

After the first 6 months, you will participate in 3 remote follow-up appointments to complete the study participation of 2 years.
