Magnetic Peripheral Nerve Stimulation (mPNS) for Chronic Pain

Area of Science:

• Neurology
• Pain Management
• Medical Devices

Background:

• Neuropathic pain, often chronic and intractable, presents significant challenges in treatment.
• Traditional electrical peripheral nerve stimulation (PNS) is an option, but requires invasive techniques or implants.

Purpose of the Study:

• To evaluate the efficacy of magnetic peripheral nerve stimulation (mPNS) for treating chronic neuropathic pain.
• To assess mPNS as a non-invasive alternative for pain management.

Main Methods:

• A retrospective case series of 24 patients with chronic neuropathic pain (post-traumatic/postoperative).
• Patients were treated with mPNS and followed for 3 months.
• Data analyzed using observational methods and mixed model for repeated measures.

Main Results:

• Significant pain reduction observed at 1 month post-treatment (average 3.8-point decrease on VAS).
• Pain relief was durable up to 3 months.
• Two-thirds of patients responded, with an 87% average pain reduction and 58.3% opioid reduction.

Conclusions:

• mPNS shows promise for chronic neuropathic pain, comparable to traditional PNS.
• mPNS offers a non-invasive treatment option, avoiding implants and surgical procedures.
