Back pain, one of the leading reasons people seek medical care, affects most
people at some point in their lives. The most common causes of back pain are
sprains, strains, or spasms usually brought on by improper lifting techniques,
poor posture, or an unhealthy ergonomic environment. Spinal conditions such
as stenosis,
osteoarthritis,
osteoporosis, or disc problems can also lead to
serious and often chronic back pain.
Typical treatments for chronic back pain include:
· Medications such as NSAIDs, steroids, and anti-depressants
· Injections such as epidural steroid injections, nerve blocks, and trigger
point injections
· Physical therapy
· Biofeedback
· Newer technologies such as IDET (Intradiscal Electrothermoplasty) and
Radiofrequency Discal Nucleoplasty which use fine-gauge needles and either
heat or radio waves to treat pain
· In rare cases, surgery or the implanting of pumps and stimulators under
the skin that administer medications or electrical pulses to treat pain
Today, another option recently approved by the Food and Drug Administration
(FDA) is available for patients suffering from chronic low back or neck pain.
It is a non-surgical treatment called Percutaneous Neuromodulation Therapy (PNT).
How PNT Works
It is now understood that even a single episode of back pain can cause the nerve
cells that transmit pain signals to become "hypersensitive", even after the
injury has healed. This can lead to repeated bouts of pain even without repeated
injury. Electrical stimulation is one therapy that, when applied to the deep
tissues in the back, can provide relief for certain types of chronic pain. PNT
is that type of therapy.
PNT uses very thin needle electrodes that are inserted directly into the deep
tissues in the area of the spine causing the pain. The specific placement of
these electrodes and the delivery of electrical stimulation help "calm" the
hypersensitivity of the nerves.
For patients suffering from chronic or recurring low back pain, especially
those who have tried other conservative pain management treatments with little
or no success, this may provide the relief they are looking for.
The Benefits of PNT
PNT is a non-invasive, low-risk procedure that can help treat pain in its early
stages. This may be able to reduce the number of patients who progress to more
debilitating, long-term pain that can persist for months or even years. PNT
treatments and the pain relief they provide may also help patients increase
their activity levels, improve their quality of sleep, and reduce their need
for pain medications.
The Procedure
PNT is a non-surgical procedure that can be done in a physician's office.
The patient lies face down on an examination table. Using light adhesive strips,
10 electrodes are placed on the skin in the affected area of the back. These
electrodes, called "Safeguides", include ultra-thin needles (three times thinner
than a human hair) that are inserted into the skin. The physician then administers
electrical stimulation to the nerves through the needle electrodes. Patients
may feel a warm tingling sensation where the electrodes are placed, but the
discomfort should be minimal. PNT treatment sessions only take about 30 minutes.
Most patients report no side effects from the procedure and are immediately
able to return to normal daily activities or work.
Depending on the complexity of the spinal condition, it may take several PNT
sessions for patients to feel any measurable pain relief. In fact, most patients
should be ready to commit to a course of at least 3-4 sessions to effectively
evaluate the therapy. Treatments may be done 1-2 times per week and can be used
alone or in conjunction with other pain management therapies.
Talk to Your Doctor About PNT
If you are suffering from chronic neck or back pain, and think PNT might be
helpful, talk to your physician. Together you can decide if the procedure is
right for you.
