Pain Treatment Center
The IMPC Pain Treatment Center is a medical unit specializing in the care of patients suffering from chronic pain. It combines the knowledge and resources of a treatment of pain with the cutting-edge technologies of a radiology center. The opening of this unit at Clinique Blomet represents a new approach to pain diagnosis.
Thanks to medical imaging techniques such as MRI, CT and X-ray, radiologists can precisely visualize the anatomical structures and pathological processes that may contribute to pain. This enables more precise identification of the source of painThis leads to more targeted treatment options.
In addition, by using image-guided injection techniques (infiltrations), or pulsed radiofrequency, doctors can deliver treatments directly to the source of pain, thus increases efficacy and reduces undesirable side effects. This interventional approach offers an alternative to conventional pharmacological treatments and enables more direct pain management.
By combining these technological advances with a multidisciplinarythe center offers patients a better understanding of their pain, as well asa wider range of treatment options.
What is pulsed radiofrequency?
Pulsed radiofrequency is a technique used in pain medicine to relieve chronic pain. It involves applying high-frequency electrical pulses to the specific nerves responsible for pain, temporarily blocking the transmission of pain signals.
In the pulsed radiofrequency procedure, a thin electrode probe is inserted close to the nerve or targeted area. The probe then emits high-frequency electrical current pulses, generating heat in the surrounding tissue. This heat inhibits the nerve fibers responsible for pain, thus reducing the painful sensation.
The special feature of pulsed radiofrequency is that it uses intermittent electrical pulses rather than continuous current. This enables selective targeting of specific nerve fibers without damaging surrounding tissue. What's more, the pulsing technique helps minimize side effects and enhance treatment efficacy.
Pulsed radiofrequency is commonly used to treat conditions such as joint pain, lower back pain, neuralgia, migraines and other forms of chronic pain. The benefits of this technique include reduced pain, improved functionality and a longer duration of relief than other temporary treatments.
How does pulsed radiofrequency work?
A pulsed radiofrequency acts by disrupting the pain signals sent to the brain. It targets the specific nerves responsible for the pain and uses a special gentle heat to reduce their ability to transmit pain signals.
How does the gesture work?
A radiofrequency treatment, whether pulsed or thermal, is carried out by a radiofrequency technician. specialized physician, such as an interventional radiologist or anesthetist.
Here are the general steps involved in a radiofrequency procedure:
1. Local anesthesia or sedation
Depending on the site and the scope of the procedure, a local anaesthetic or mild sedation may be administered to ensure your comfort during the procedure. Your doctor will discuss anesthesia options with you.
2. Placement of electrode or probe
Using a guided imaging technique such as ultrasound, CT or fluoroscopy, the doctor will guide an electrode or probe through the skin to the target site. The electrode or probe is usually inserted through a small incision.
3. Position check
Once the electrode or probe is in place, its precise positioning is confirmed using real-time imaging. This ensures that the desired target is reached and that important adjacent structures are avoided.
4. Minimally invasive treatment
Once the position has been confirmed, the radiofrequency generator is activated. In the case of pulsed radiofrequency, electrical pulses will be emitted through the electrode to disrupt pain signals. In the case of thermal radiofrequency, thermal energy is delivered to heat and destroy target tissue. The procedure takes 2 to 5 minutes.
5. Monitoring
During the procedure, you will be monitored continuously for any adverse reactions or complications. Your doctor will monitor your comfort and adjust the parameters of the procedure as required.
End of procedure: Once the treatment is complete, the electrode or probe will be removed. You will be monitored for a short period after the procedure to make sure you are recovering well.
Is the technique dangerous? Is the scientific evidence sufficient?
Pulsed radiofrequency (PRF) is considered to be one of the world's leading safe procedure when performed by qualified health professionals. The first pulsed RF treatments and scientific studies on the subject date back more than 20 years.
However, as with any medical treatment, there are potential risks and considerations to take into account.
Undesirable effects
Although rare, adverse effects can occur after a PPN. These may include local irritation, increased sensitivity, bruising, infection or allergic reactions to drugs used during the procedure. Pain may also temporarily increase after PPN before decreasing.
Rare complications
More serious complications may occur, such as lesions of the skin.
infection or excessive bleeding. However, these complications are extremely rare.
Scientific evaluations
Scientific evidence for the efficacy of PBR varies according to specific indications. A large number of scientific studies have shown promising results in the relief of chronic pain.

Pulsed radiofrequency applications
Chronic back pain
Chronic back pain, whether caused by herniated discs, spinal osteoarthritis or other spinal problems, can be alleviated with pulsed radiofrequency. This procedure specifically targets the nerves responsible for pain in the back region, offering patients significant relief.
Postoperative pain
Pulsed radiofrequency can also be used to treat post-operative pain. It offers effective relief to patients undergoing surgical procedures, particularly those that may result in persistent pain.
Osteoarthritis of the knee
Osteoarthritis of the knee is a common condition in the elderly, characterized by joint pain and stiffness. Pulsed radiofrequency can be used to relieve the pain associated with this condition, improving patients' quality of life.
Fibromyalgia
Fibromyalgia is a chronic condition that causes widespread muscle and joint pain. Pulsed radiofrequency can help reduce pain in people with fibromyalgia, offering long-term relief.
Lumbago
Low back pain can be effectively treated with pulsed radiofrequency. This procedure targets the nerves responsible for pain in the lumbar region, relieving symptoms and improving back functionality.
Morton's neuroma
Pulsed radiofrequency (PRF) has been studied and used as a treatment option for Morton's neuromas, which are painful conditions of the nerves between the toes.
Effectiveness: Scientific evidence on the effectiveness of PPN for Morton's neuroma are limited, and the results of studies are encouraging. Some studies have suggested that PBR can provide significant pain relief and improve function in some patients. It is important to note that results may vary from one individual to another.
The supra-scapular nerve at the shoulder
Indications: Shoulder RFP may be considered for the relief of chronic pain associated withconditions such as retractile capsulitis (frozen shoulder), osteoarthritis of the shoulder, tendonitis or neuropathic pain specific to the shoulder.
Neuralgia
RFP is often used to treat neuralgia, which are pains caused by nerve irritation or damage. For example, trigeminal neuralgia or Arnold's neuralgia , Morton's neuromas , coccygodynia , pathology of the pudendal nerve ... can benefit from pulsed radiofrequency.
Joint pain
RFP can also be used to relieve joint painparticularly in joints such as the knee, shoulder and hip. This can be beneficial for people suffering from osteoarthritis or other painful joint conditions.
