A cranial electrical stimulator also known as cranial electrotherapy stimulation, transcranial electrotherapy, transcranial electrical stimulation, and electrosleep, (e.g., Alpha-Stim SCS) is a small, battery-operated device that delivers low level electrical stimulation (i.e., microcurrent) to the brain through electrodes that attach to the ear lobes via clips. Its proposed indications include, but may not be limited to, anxiety, depression, insomnia, fibromyalgia, Alzheimer’s Disease, and pain-related disorders.
Auricular electrostimulation is a type of ambulatory electrical stimulation of acupuncture points on the ear. Devices, including the P-Stim™ and E-pulse, have been developed to provide continuous or intermittent stimulation over a period of several days. Also known as auricular electro-acupuncture, this type of electrostimulation is being evaluated for a variety of conditions, including pain, depression, and anxiety.
