Peripheral Nerve Stimulation Using High-Frequency Electromagnetic Coupling Technology to Power an Implanted Neurostimulator With a Separate Receiver for the Treatment of Peripheral Neuropathy.

BACKGROUND: Chronic pain impacts multiple facets of daily life, including mental health, mobility, and ability to work. Conservative management strategies often fail to control pain adequately, and pharmaceutical treatments involve unwanted side effects. With the development of specialized technology, peripheral nerve stimulation (PNS) has emerged as a treatment for pain caused by peripheral neuralgias that cannot be managed with conservative strategies. CASE REPORT: This was a retrospective study collecting data from the electronic medical records of patients. A chart review was conducted for all eligible study patients. Patients who underwent a PNS trial for the treatment of peripheral neuropathy were recruited to participate in this study. Verbal Rating Scale (VRS) scores decreased from 7.8 ± 1.6 to 1.6 ± 1.1 after the trial. At 3 months, VRS scores decreased to 2.1 ± 2.7. CONCLUSIONS: The Freedom^® PNS System is a safe and effective treatment modality for the management of pain caused by peripheral neuropathy.
