Neurostimulation devices are implantable, programmable medical devices that deliver electrical stimulation to specific parts of the patient's brain, spinal cord, or peripheral nervous system to help treat various conditions, including chronic pain, movement disorders, epilepsy, and Parkinson's disease
Neurostimulation is the purposeful modulation of the nervous system's activity using invasive (e.g. microelectrodes) or non-invasive means (e.g. transcranial magnetic stimulation or transcranial electric stimulation, tES, such as tDCS or transcranial alternating current stimulation, tACS). Neurostimulation usually refers to the electromagnetic approaches to neuromodulation.
Components of the Spinal Cord Stimulation System. A spinal cord stimulation system consists of two implanted components: Neurostimulator — Rechargeable or non-rechargeable implanted power source that generates electrical pulses according to programmable neurostimulation parameters and features.
Neurostimulation technology can improve the life quality of those who are severely paralyzed or suffering from profound losses to various sense organs, as well as for permanent reduction of severe, chronic pain which would otherwise require constant (around-the-clock), high-dose opioid therapy (such as neuropathic pain and spinal cord injury). It serves as the key part of neural prosthetics for hearing aids, artificial vision, artificial limbs, and brain-machine interfaces. In the case of neural stimulation, mostly an electrical stimulation is utilized and charge-balanced biphasic constant current waveforms or capacitively coupled charge injection approaches are adopted. Alternatively, transcranial magnetic stimulation and transcranial electric stimulation have been proposed as non-invasive methods in which either a magnetic field or transcranially applied electric currents cause neurostimulation.
Neurostimulation is an advanced treatment for reducing chronic pain and improve the quality of life of people who are paralyzed or suffer from severe losses to sense organs. Neurostimulation devices are often surgically implanted in the patient and function with the help of thin wires or leads. These devices function by initiating stimulation of nerve impulses or by inhibiting pain signals produced at target sites that include the autonomic nervous system, deep nuclei of the brain, peripheral nervous system, and central nervous system.
