Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 to 99 who have chronic pain from myofascial pain syndrome persisting for at least three months.

Probably not a fit

Patients with active implants, allergies to study medications, or those who are pregnant may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical investigation evaluates the effectiveness of the Sonodyn device, which combines low-energy ultrasound, electrical, and magnetic field stimulation, in treating chronic myofascial pain syndrome. The device is designed for non-invasive application over specific trigger points associated with pain in the lower back, neck, and tension headaches. Patients will receive either the active treatment or a sham treatment to assess the device's efficacy. The study aims to provide relief for individuals suffering from persistent pain that has not responded to conventional therapies.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate chronic pain for patients suffering from therapy-resistant myofascial pain syndrome.

How similar studies have gone: While the approach of using combined low-energy stimulation techniques is innovative, similar studies have shown promise in treating chronic pain conditions.
