What Is Peripheral Nerve Stimulation (PNS)?
PNS involves the use of electrical impulses to modulate pain signals along peripheral nerves, offering relief to individuals with chronic pain. Scientific studies have shown that PNS can be effective in managing various types of pain, including acute postoperative pain and chronic pain conditions.
How Does PNS Work?
Peripheral nerve stimulation comprises helically coiled electrical leads that guide an applied current toward afferent neurons responsible for sensory innervation in the affected region. The underlying principle involves modifying nerve fibers with the applied current. This modification disrupts the central processing of pain signals at the spinal cord level by reshaping the perception and processing of pain and providing relief in the targeted area.
Who is a Good Candidate for PNS?
Generally, the ideal candidates for PNS are:
Individuals with chronic pain, especially those for whom conventional treatments, such as medications or physical therapy, have not provided adequate relief.
Specific types of pain, such as neuropathic pain, which is caused by nerve damage. This includes conditions like nerve injuries, sciatica, and some types of chronic back pain.
No pain relief from other treatments
A successful trial stimulation period with a temporary PNS system indicates that a permanent implant may be beneficial. This trial helps to assess how the body responds to the stimulation.
Good overall health. This reduces the risk of complications during and after the procedure.
The recovery time for a peripheral nerve stimulator implant varies from individual to individual. However, studies suggest that most patients resume normal activities within a few weeks post-implantation, gradually improving comfort and mobility.
Scientific evidence supports the effectiveness of implanted nerve stimulators in managing chronic pain. Studies on peripheral nerve stimulation have demonstrated positive outcomes, providing sustained relief for conditions such as chronic pain following amputation and in managing chronic pain.
The procedure for a nerve block varies, depending where the targeted nerve is. The general steps in a nerve block injection include:
Consultation: Dr. Etelzon will assess the patient’s medical history and pain condition. This stage is crucial in determining whether PNS is a suitable option. Dr. Ilana Etelzon, a board-certified Physical Medicine and Rehab/Interventional Pain Management Specialist, is the finest choice for pain management in New York City. She relies on her knowledge and experience to analyze your condition, diagnose the source of your pain, and determine a treatment plan tailored to your needs.
Trial Period: Following a successful consultation, a temporary PNS device is implanted during a trial period. This allows patients to experience the therapy and evaluate its efficacy in managing pain. A typical trial period for a peripheral nerve stimulator usually spans 3 to 5 days. During this time, the patient is encouraged to engage in activities previously hindered by pain under certain physical activity limitations to prevent dislodging the trial leads. The effectiveness of the trial may become apparent immediately or over a few days. After the trial, Dr. Etelzon can easily remove the stimulator leads in a simple office procedure.
