These days there is much
talk about PEMF or Pulsed Electromagnetic Field devices. These are devices that
are touted to provide an effective alternative therapy for pain management
and for the alleviation of various other
health problems. But with the huge success of the PEMF devices, there has been
an influx of such machines in the market. It is but natural to get confused
regarding the best device. A number of small manufacturers have entered the
market with cheap, small hand held devices, each claiming to give the best
results.
So, when you set out to
look for an ideal PEMF device, you want to how one differs from another. Here
are the features that set the various devices apart:
Power Level: It is a known fact that PEMF devices produce
a magnetic energy. Some of these devices produce energy that is as little as
the Earth’s magnetic force while there are others that are capable of producing
energy that is 10,000 times more powerful than the Earth’s magnetic force. The devices with low power are use for bone
healing and better cellular health. For the recovery from accidents, surgery,
trauma and sports injuries devices with high power are used. Pain management is
equal with both types of devices, but the ones with high power are more
effective.
Shape of Waveform: Different PEMF devices are based on different
waveforms. The continuous waveform PEMF devices produce a sine wave, a saw
tooth, a square or a custom waveform. A biphasic short duration pulse is
produced by the pulsed output PEMF devices.
Pulsed or Continuous Waveform: This is not a rule but
as has been found, the high power PEMF devices have a pulsed waveform while the
low power devices have a continuous waveform. Each of these waveforms has their
significance.
Control of Frequency: Frequency can be controlled in the high power
PEMF devices as the user has a variable control of the pulse rate. However, the
low power devices come with preset frequencies, which the users can choose
according to their requirement.
Treatment Duration: The duration of treatment depends upon the
power level of the device and the intensity of the problem. The duration could
last from three minutes to hours.
Now that these
differences between the various PEMF devices are clear, it would be easy for
you to find the device that best suits your requirement. However, if there is
still some confusion, you can take the help of your medical practitioner.
