The FlexPulse is designed to provide a variety of frequencies to accomplish different stimulation goals, most typically based on understanding brainwave frequency patterns.
Any frequency chosen for treatment will have the same basic PEMF biologic actions as well as actions on the nervous system based on its respective brainwave frequency band. All of the frequencies in the FlexPulse will have similar basic biologic actions, and some unique biologic effects specific to that frequency. Most of the time the frequencies will be chosen based on the effects of the particular brainwave frequency band.
The frequencies and their respective frequency bands have been primarily selected based on their effects on the body and the nervous system through a process called brainwave entrainment. Brainwave entrainment has been well studied scientifically. One of the earliest descriptions of this were found from scientific research into the effects of rhythmic light and sound stimulation in the mid-1930s. Scientists discovered that the electrical rhythms of the brain, or brainwaves, tended to assume the rhythm of a flashing light stimulus. This process was called entrainment. For example, when a strobe light was flashed at a frequency of 10 Hz into the eyes of the subject monitored by an electroencephalogram [EEG], the subject’s brain waves tended to fall into a 10 Hz frequency. Various scientists discovered that such light stimulation could have a variety of beneficial effects, such as increasing IQ scores, enhancing intellectual functioning, greater synchronization between the 2 hemispheres of the brain, relaxation, improved sleep, pain relief, and enhanced immune function.
Since these early studies, a whole new branch of science has developed called neuroscience, which included neurofeedback. Neurofeedback is based almost completely on rebalancing the brain using entrainment techniques. Another way to understand entrainment is to explain it in terms of how radios and TVs work. Each radio and TV station is assigned a frequency within which it must broadcast its signals. This way the station signals do not overlap or interfere with one another. The signals are produced by transmitters at the broadcast stations. Our TVs and radios have tuners in them. When we change the station in the tuner, we expect the tuner to begin to resonate in synchrony with the broadcast signal frequency. Once the signal is locked in and refined by the tuner, a clear sound and/or picture is produced. If resonance synchronization does not happen, then the picture will be blurry or the sound will be just static noise.
