The Science Behind FlexPulse
Rationale and science behind the FlexPulse PEMF programs.
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.
The human brain and nervous system (and for that matter all the cells in the body) act like tuners to receive signals from outside the body. Once the signal is tuned properly, the body begins to resonate synchronously (entrain) with the signal. Healing PEMFs operate with this entraining, signal-synchronization process to perform the desired actions in the body.
Just as sound and light can produce effects on the body through entrainment, so too can electrical stimulation and pulsed electro-magnetic field (PEMF) stimulation. Generally, whatever we can do with electrical stimulation can be done better and more safely with PEMF stimulation, because of the degree of penetration of the body and brain with PEMF signals.
There is much research to support the effects of entraining PEMF stimulation to produce benefits for the body. One such example is that the biological effects of short-term exposure to low-frequency low-intensity PEMF were studied (Volynskii ) in adult rabbits. Electroencephalography (EEG) showed that adult rabbits assumed the 5-8-Hz rhythm of the PEMF; this entrainment effect was less pronounced for 1-2-Hz.
It was mentioned above that cranial electrostimulation [CES] was also used to produce brainwave entrainment. This was studied (Schroeder ) in normal individuals using EEG to monitor the brainwave changes. The study individuals received concurrent administration of 0.5 and 100 Hz or sham CES in a randomized, double-blind crossover design study. Treatments were for 20 minutes per session. Relative to sham control, 0.5 and 100 Hz CES caused alpha band frequency changes. 100 Hz CES also caused the alpha brainwave frequency band to decrease in frequency and the beta band intensity also decreased. These frequency distribution shifts suggest that helpful changes in mental state would be expected to occur.
Behavioral and neurophysiological changes have been reported after exposure to extremely low frequency PEMFs in both animals and in humans. Laboratory studies analyzed the effect of PEMFs on nerve cell cultures and showed an increase in neurotransmission. Transcranial brain stimulation was used to study (Capone) noninvasively the effect of PEMFs on several measures of brain glutamine activity in healthy volunteers. The PEMF signal was 75 Hz with a peak intensity of 1.8 milli-Tesla. 45 min of PEMF brain stimulation significantly enhanced brain activity by about 20%. These results were comparable to that seen with pharmaceuticals. There were no side effects reported. Sham field exposure produced no effects.
