A peripheral nerve stimulator (PNS) is a medical device designed to alleviate chronic pain by stimulating specific peripheral nerves. This minimally invasive treatment option is particularly effective for managing pain associated with conditions such as neuropathy, complex regional pain syndrome (CRPS), and post-surgical pain. The device consists of a small pulse generator implanted under the skin, typically in the region near the affected nerve, and electrodes placed along the targeted nerve pathway.

These electrodes emit gentle electrical pulses that modulate nerve activity, interrupting pain signals before they reach the brain. This neuromodulation can lead to significant pain relief and may also enhance the function of the affected limb. Peripheral nerve stimulation is often considered when other conservative treatments, such as medications or physical therapy, have failed to provide adequate relief. The procedure is reversible and adjustable, allowing healthcare providers to tailor the stimulation to the patient’s unique needs. By reducing pain, PNS can help improve patients’ quality of life, facilitating better engagement in daily activities and reducing the need for ongoing pain management strategies.
