Implanted Stimulator a 'Paradigm Shift' for Low Back Pain?
A safe and minimally invasive implanted stimulation device is getting mostly positive reviews from neurosurgeons, with some experts saying it represents a "paradigm shift" in the treatment of mechanical low back pain. Results from a multicountry study show that the ReActiv8 device (Mainstay Medical Limited) is efficacious, improving function and reducing pain for up to 2 years for patients with back pain caused by loss of function in the multifidus muscle.
@sandy Patients with chronic neuropathic low back pain may be candidates for surgical procedures, such as fusion or decompression. However, these are not options for the larger population of individuals with nociceptive mechanical pain, many of whom have dysfunction of the multifidus muscle. The current study included 204 relatively young patients (mean age, 47 years) who were enrolled at 26 sites around the world, including 16 sites in the United States. Baseline score on a low back pain visual analogue scale (VAS) was 7.3 cm, and the baseline Oswestry Disability Index (ODI) score was 39 points.
