Vagus Nerve Stimulation for TMJ Disorder

This trial tests a new method to help premenopausal women with temporomandibular disorders (TMD), which can cause jaw pain and limited mouth opening. The treatment, called nVNS Treatment, uses a device to stimulate the vagus nerve without surgery, aiming to reduce pain by affecting brain and gut connections. Ideal participants are premenopausal women experiencing jaw pain, difficulty opening their mouths, or noise in the jaw joint. Participants must visit the clinic regularly for treatments and tests over eight weeks. As an unphased trial, this study provides a unique opportunity to explore innovative treatment options for TMD.

Research has shown that non-invasive vagus nerve stimulation (nVNS) is generally well-tolerated. This treatment avoids surgery or skin penetration, making it safer than invasive methods. It uses a device on the skin to stimulate the vagus nerve, aiding in pain management and other body functions.

Unlike the standard treatments for TMJ disorder, which often involve medications like pain relievers or muscle relaxants, physical therapy, or even surgery, the nVNS (non-invasive Vagus Nerve Stimulation) treatment offers a unique approach. This treatment is different because it targets the vagus nerve using a non-invasive device that is applied externally, potentially reducing pain and inflammation without the need for medication. Researchers are excited about nVNS because it could offer a new, drug-free option with fewer side effects for those suffering from TMJ disorder. Additionally, its non-invasive nature makes it a convenient and accessible treatment option for patients.

Research has shown that non-invasive vagus nerve stimulation (nVNS) may help with chronic pain. It sends gentle electrical signals to the vagus nerve, which extends from the brain, through the face, and into the abdomen. This stimulation is believed to enhance communication between the brain and the gut, potentially reducing pain. Early results suggest that nVNS could be effective for various pain conditions, although its effects on temporomandibular disorders (TMD) are still under investigation. Participants in this trial will receive the active nVNS treatment, which is non-invasive and doesn't require surgery, making it an appealing option for many.¹⁶⁷⁸⁹
