Rio Grande Neuroscience (RGN’s) PEMF technology is a portable treatment that inductively delivers a low-power electric field to underlying tissue. PEMF is a Class II FDA-cleared treatment for postoperative pain and edema and in randomized controlled clinical studies has been found to be safe and able to significantly reduce pain, narcotic pain medication use, edema, and inflammatory cytokine production. RGN has repurposed PEMF for treating mild traumatic brain injury and multiple sclerosis, based on studies demonstrating its anti-neuroinflammatory and neuroprotective effects. Preliminary clinical data (Harvard University) indicate that at-home treatment with the PEMF TheraCapTM reduces symptoms in patients with post-concussion syndrome.
