Before you start looking at what Best Home Ultrasound Therapy Machine has to offer you, there is a very important step that you need to take first. And this step is something that you should, in no way, skip. You should make sure to check that the device you are getting has been cleared by the FDA as an over-the-counter (OTC) class II medical device.
If, while you are searching for a machine, you do come across a device that has not been cleared by the FDA, you should proceed with caution. Companies are not permitted legally to market their products and services unless they have this clearance.
For a more organized and methodical approach, these can be put in sub-sections.
Programs and modes
Not all, but most modern-day OTC TENS units come with preset programs (these are also known as modes by some makers). These are made to make it easier to use.
What programs or modes does the machine have and what are they for?
Would you use them, and if so, how often?
Some machines like the TENS 7000 have less modes but they offer fine-tuning of the treatment. You should know, though that they would require more user input, and you will need to be familiar with things like pulse-width and wavelength.
Many people, especially those who are buying for the first time go for devices that have special preset programs because they take less work to operate.
Many of the devices on the market today are dual channel with independent intensity controls.
This type of machine can be used with two or four pads (electrodes) at one time. Each channel has two pads, and you can adjust the strength of the treatment separately for each channel.
The most important thing to take note of is that you can always use a dual channel device with two pads or four, but you cannot use a single channel machine with more than two.
