CES Cranial Electrotherapy Stimulation StimTen's frequencies & technical information
CES cranial electrotherapy stimulation is a class of non-invasive, transcranial pulsed-current stimulation that applies a particular amplitude, frequency, and waveform to patients. CES devices have two parts: a box to control settings, and a set of electrodes. The most comfortable electrode placement is earlobe based on patient feedback, there are some models that require temple placement as well. Amplitude and frequency are also variable, with most CES devices allowing up to 5 mA and 0.5-500 Hz, respectively. Waveform can be square or sinusoidal. The stimtens.com MyoCalme CES device provides an output voltage of .80 Vpp @ 500 Hz with a Symmetrical biphasic square wave. The StimTens frequency is 0.5 Hz with a pulse width of 240 msec to one second.
There is still debate on the efficacy of CES on its intended treatment targets of insomnia, anxiety, and mood. Although CES has been shown to affect neurotransmitter and neurohormone concentrations, while changing oscillatory band power in EEG recordings.2 Mental Health America (MHA) suggests clinical examination of CES in ADHD, anxiety, mood, pain, and insomnia. Additionally, CES hasn’t shown many side-effects in literature; vertigo, irritation, and headache are three which are noted. You may discover more information on this product at www.stimtens.com
