What is the difference between CES therapy devices?(cranial electrotherapy stimulation)
This is a question that comes up quite often, and the honest answer is......they're all actually pretty similar, well, at least the FDA approved CES therapy devices are.
The most important feature in a CES therapy device is to make sure that it is FDA cleared. You will need authorization in order to purchase an FDA cleared cranial stimulator, these can be acquired through your health professional or, in some cases, online at the website that you wish to purchase.
Cranial electrotherapy devices work by sending a slight electrical pulse to the brain, this triggers the brain to balance hormones that affect mood, anxiety and insomnia symptoms. All CES devices do this, it's just that some perform this actions somewhat differently than others and some include some extra features.
Some of the most popular CES cranial stimulation devices that are reviewed are: The Alpha Stim, The Fisher Wallace Stimulator, The MyoCalme and the CES Ultra. These are all good devices and you really can't go wrong with any of them.
The Alpha Stim, MyoCalme and CES Ultra work with ear clip electrodes as a means to reach the nerves that lead to the brain. These are convenient and comfortable to use. The MyoCalme and CES Ultra can also be used with cloth electrodes that can be placed behind the ear as an alternative.
The Fisher Wallace Stimulator, on the other hand, uses wet sponges in order to reach the nerves that lead to the brain, this method also works well. People with longer hair may be advised that it can interfered with the conductivity, also, there are some individuals that find the wet sponges somewhat unsettling and not quite as portable as the ear clips.
Both the Fisher Wallace Stimulator and the Alpha Stim do use electrodes that must be replaced often, this can lead to an additional expense above and beyond the cost of the original CES stimulator as an FYI.
There are many ces therapy reviews out there and will point out the positive and negatives of various machines. In general, you will want to look for a ces therapy machine that offers a 5Hz. frequency to treat insomnia, anxiety and depression symptoms. The 5Hz is considered best to treat these conditions, although there are some that may feel otherwise.
