Peripheral nerve stimulation (PNS) is a medical procedure used to treat chronic pain by delivering electrical stimulation directly to peripheral nerves. This technique involves implanting a small device, similar to a pacemaker, near the affected nerves. The device generates mild electrical pulses that interfere with the transmission of pain signals to the brain, thereby reducing the perception of pain.
PNS is commonly used to manage various types of chronic pain, including neuropathic pain, complex regional pain syndrome, and other conditions that do not respond well to conventional treatments. It can provide significant relief for individuals who experience persistent pain despite other interventions.
The procedure for peripheral nerve stimulation typically involves the following steps:
- Evaluation: Before undergoing PNS, patients undergo a thorough evaluation to determine if they are suitable candidates for the procedure. This may include medical history review, physical examination, and diagnostic tests to identify the source of pain.
- Implantation: During the implantation procedure, the surgeon makes a small incision near the targeted nerves and places the stimulation electrodes in the desired location. The electrodes are connected to a pulse generator, which is usually implanted under the skin in the buttock or abdomen.
- Programming: After the surgery, the device is programmed to deliver electrical impulses at specific frequencies, intensities, and durations tailored to the patient’s needs. The programming can be adjusted and optimized over time to achieve the best pain relief with minimal side effects.
- Follow-up: Patients are closely monitored after the procedure to assess the effectiveness of the stimulation and make any necessary adjustments to the settings.
