Rhythmic sensory stimulation treatment reduces chronic pain

A parallel randomized controlled trial examining the effects of rhythmic sensory stimulation of fibromyalgia

Published: March 1, 2019

Fibromyalgia is a pain syndrome characterized by chronic widespread pain for which no cause can be identified (e.g., tissue damage or inflammation). Symptoms often includes chronic fatigue, sleep disturbance, decrements in physical functioning, and disruptions in psychological functioning such as anxiety, mood disturbances, memory problems, and lack of well-being.

Vibratory analgesia is a well-described phenomenon whereby sensory stimulation delivered to the skin can reduce pain. Mechano-acoustic vibrations have been extensively used to address acute pain during orthodontic and cosmetic procedures, and is a well-established technique in orthopedic practice and physiotherapy to reduce muscle soreness, low back pain, and orofacial pain. However, little is known regarding the application of vibroacoustic stimulation in the treatment of chronic pain conditions.

In this study, fibromyalgia patients received vibrotactile stimulation from a continuous sine wave single-frequency stimulation (40 Hz) for 30 minutes, five days per week, over five weeks.

Results indicated that there were statistically significant changes from baseline to post-treatment in measures of fibromyalgia symptom severity, pain interference, depression, and sleep quality.

A parallel randomized controlled trial examining the effects of rhythmic sensory stimulation on fibromyalgia symptoms

This double-blind, two-arm parallel randomized controlled trial investigated the effects of gamma-frequency rhythmic sensory stimulation on fibromyalgia. We were interested in whether rhythmic sensory stimulation would promote significant changes in fibromyalgia and associated symptoms, and...

I clicked on the link and the therapy system acoustic mat is already sold out at $499.99 with free shipping! People are desperate to feel better. I hope it works for them, even if the science isn't settled.
